Casio CZ/ VZ/ FZ - Pro Series

Heyo,

I've been using my CZ-1000 for years now, and it's serviced me well.

However, recently the power jack has been acting a bit tempermental; 
it's a little touchy now. Not good. I was wondering if anybody else had 
similar problems, and if so, what had they done?

Also (and I understand this might be a bit of a stretch), but I 
recently acquired a Korg Poly-800. It's similar to the CZ-1000, but 
it's got a dedicated 3V watch battery inside, keeping the patches even 
when it's unplugged and there are no C or D cells in back.

Is anything like this possible with the CZ-1000? I've scoured the web, 
but I couldn't find anything. What do you guys think? It'd make me love 
my CZ-1000 even more.

Chris

This is a common problem.  Possibly the solder joints have come loose- just 
re-solder them.  Or if the jack is bad, it's easy to replace.  Get one from 
a decent parts supplier or scavenge from something else.

As far as I know the Poly 800 doesn't come with a battery.  It's fairly 
common to add as a modification but I think only the EX-800 and Poly 800 II 
actually come with memory backup batteries.  I don't think it would be hard 
to add a battery to a CZ but I don't know of anyone who has done it.

It was a Poly-800 Mk II, so it had a dedicated 3V battery installed on 
the board -- the 3V battery had just run out, so I soldered on a new 
one.

If we could hack the CZ-101 / CZ-1000 / etc. to have this sort of 
dedicated memory, it would finally end our dependency on six expensive 
D cells (which I've found rapidly run out, even when I ONLY use the AC 
adapter!).

And in addition, that 3V cell in the Korg Poly-800 lasts for a good 7 
years or so. Let's brainstorm.

Any schematics anywhere?

    Hi.  I used to have this problem with my CZ1000 all the time!  I dragged 
it out a while ago, and I couldn't get it to work, only made strange buzzing 
sounds when powered on.  I used to have to slightly wiggle the power connect 
to get a good connection or else the power light would start to blink and 
shut off after 10 seconds or so.  I've also run in to the same problem with 
other synth's as well.   If you can get to it, see if there's a way to 
resolder the connection on the circuit board where the power jack is 
located.  Hope this helps.

    I sold my Poly 800mkII years ago, and I could have swore it had a way to 
run off battery's, but evidently not.  The reason I thought was because it 
have knobs to hook a strap to and you could play it like a keytar.    Also, 
when I took my CZ1000 out to play it, the battery's had corroded, and I 
think one of the reasons it doesn't work anymore is because the battery's 
leaked into the case.

The problem you're facing probably isn't that the batteries get drained- 
alkaline batteries (or whatever you're using) don't have a very good shelf 
life.  Lithium batteries (used for memory backup) last much longer.

As for schematics, I haven't seen any around.  There doesn't seem to be much 
of a scene for modding/repairing CZ synths.

If we can just figure out what part of the synth needs to keep that 
voltage running through it, we can just find the +voltage / -voltage 
ports and maybe just solder on a 3V lithium watch-battery cell, like 
on the Korg Poly 800.

There's got to be some way of doing this; I can try tinkering with 
it, the CZs have that hard-reset button that resets all the presets 
so if I totally botch stuff up, hopefully I can just reset it all. As 
is, I gave up on using programmed patches, because the 6 D batteries 
just vanish -- lithium, alkaline, rechargeable, or otherwise. It's 
just not worth it spending that much money on D batteries. There must 
be a better way.

Sorry for saying this if you've considered it already, as it is quite
well-known, but I believe it's possible to fit a PP3 battery in place
of the D cells which will maintain user memory when the CZ101 is
switched off. Of course, if you turn it on without another source of
power the battery will instantly drain but it might help.

If a schematic is not possible take pictures of the battery 
connections inside the synth and the area around any of the chips 
that have 28 pins. The memory will be held on 1 or 2 of these IC's. 
If you have a voltmeter see which pins are powered by the batteries 
on these chips when the AC power is removed. Then use a 3 volt 
CR2032 lithium battery to maintain power to these pins. Isolate the 
plus side with a small diode so the synth power can't backfeed the 
lithium battery and you will have memory backup without the 6 "D" 
cell worries. If you want help I can help offline. My CZ5000 has 
this sort of setup from the factory as it uses 3 "AA" batteries to 
maintain the memory on power down. Of course the CZ5000 isn't able 
to run on batteries because of the extra options onboard. 
  Good luck and be careful! Narfman

It's not as straight-forward as it sounds.  Obviously power needs to be 
continuously supplied to the RAM chips.  And there's at least some provision 
for this, as the synth retains patches when switched off- but simply 
connecting a battery across the RAM power supply lines isn't a good idea.  
When the synth is powered up, the backup battery would then be connected 
directly across the power supply, which will possibly make the battery 
explode.  I think you could connect a diode so that power only flows from 
the battery when RAM supply voltage drops below battery voltage, BUT with 
the resultant voltage drop (about 0.7 volts), it may not be enough to hold 
the RAM contents.  You could probably find the RAM chip's datasheet and 
check.  I'm not sure how memory retaining circuits generally work, maybe the 
best approach would be to analyze the schematics of another device for 
inspiration.

An alternative would be to connect a super capacitor to the RAM power supply 
lines.  These are typically used in things like VCRs, etc. to save settings 
and things during short-term power loss.  I think the installation should be 
fairly simple, maybe a small resistor could be added to prevent a large 
surge of current when it's first charged.  It wouldn't really replace a 
backup battery, but would probably enable you to unplug the CZ for at least 
a while without worrying about it.

> It's not as straight-forward as it sounds.  
 Hi Everybody,
 Actually is it simple and straight forward. Simply connect a
9 volt battery strap to the + and - battey terminals. Connect 
a square battery holder for 4 AA. Stuff the back of the CZ
battery compartment with foam. Snap in the battery holder and
your done. Should hold the memories for at least 9 months 
without use. Mine did. The CZ 3000/5000 use 3 AA's for backup.
 I tried with 3 volts or 2 AA's but this did not hold memory.
It did work with 4.5 volts or 3 AA's, but there is no way to
mount the 3 battery holders, so I went with four or 6 volts
backup.
 So why does this work? The casio already works with battey 
backup in the form of 9 volts via 6 D cells. Built into this
circuit is a low voltage memory protect that will shut down 
the CZ when the voltage drops below a certain threshold.
Usually set at around 7.5 volts or so via an internal trimmer.
By placing only 6 volts here the CZ will not try to run off the 
batteries. If you instead placed a 9 volt type battery on the
clips, as per a mod article in Electronic Musician, the CZ
will actually run off of this battery. The poor 9 volt will last
about 5 minuts before the low voltage protect shuts it off, 
leaving the battery dead and useless. So 6 volts no problem.
 So why does the CZ cause such problems with batteries in the first
place? Another mystery that plagues many CZ users is the power jack
on the side of the CZ 101, 1000, 230S. The pin is not a standard
one as many believe. The center pin is actually 1.7mm and not the
standard 2.1mm found in many replacement power supplies. So the will
work sporadicly, giving the impression that the jack is faulty. This
condition is probably the leading cause of short battery life. The CZ
user does not reralize the power has disconnected momenarly and 
running off the internal battery backup. The ^ D cell normally only
last around 4-5 hours tops. So using 6 volts as back up eliminates 
this power problem, as now when the power is interupted the CZ will
shut off, saving the backup not draning it.
 And the proper fix for the power is to get the correct AD-5 supply
for a Casio with the 1.7mm center pin. ( Don't get the barrel end 
type that has a "L" shaped end as this will not seat property in the 
101. Get the one with a straight end.)
 Also the CZ101/1000/230S does have a super capacitor to hold the 
memory for battery changes. Depending on the condition of the cap
this will hold for at least 5-7 minuts without any battery. Just
look at the schematics.
 I'll post a pic of the required items if I can. All you need is 
a 9V battery clip, a 4 AA battery holder, and some foar rubber to 
stuff the battery compartment. Simple!

Terry (The Casio Kid)

This sounds awesome! Can you be a little more specific with where 
exactly the 9v and the four AA batteries go? Are they in series with 
eachother? Is the foam necessary?

Also, I was considering just clipping off the little input on the 
Casio AC adapter, then just soldering it to the power input, then 
actually installing the AC adapter INSIDE the CZ-1000 case. Then I 
could just use a standard computer / monitor power cable, which I've 
found to be much more reliable that those little half-inch cylinders 
at the ends of AC adapters.

... I hope that made sense.

This might explain the problems I have had with the Casio TB-1 and the 
Radio Shack power supplies I have been using for decades. Thanks.

Right Steve, I did not even think about the other Casio products
from that same time period that also use battery or adapter for
power. My HZ-600 has the same small center pin, so I would 
assume the DZ-1, RZ-1, SZ-1 would all have the same. Casio did
not really document this anywhere, but always recommend using thier
brand adapters for thier products. 
 Problem with the Radio Shack solution is they do not offer a 2.5mm
barrel 1.7mm pin adapt-a-plug? And how many times do you see a CZ-101
for sale without an adapter with a quote like "uses a standard adapter
found at any Radio Shack". This just isn't true as Casio aparently 
tried to make these a propritary power system.
 And the standard 2.5mm barrel 2.1mm pin is such a close fit many do 
not realize the problem. For instance, say a Korg adapter for the 
MS2000 or Microkorg fits right in the Casio jack and mostly works. But 
the Casio AD-5 just won't fit into the Korg since the center pin is 
slightly larger. No wonder this is an unkown problem.

I use adaptaplug J without any problems:

 Adaptaplug J conversion size: O.D.: 5.0mm. I.D.: 1.5mm

According to the web site, it's available in-store only.

Hi all,

I did the 4 AA battery clip solution as described in the quoted 
message below. It was rather easy to do, I already did the 9 volt 
battery mod as described in a CZ101 mod article in Electronic 
Musician (E.M.). So all I had to do was go out and by some batteries 
and a battery clip. 
Sofar it works well, but now I do wonder: would it be wise to install 
a 6 volt 1400 mAh (1400 mAh should be safest) nicd battery, connect 
it to the power supply input so that the battery can charge when the 
psu is plugged in?
I know it can be don rather easily, but would it work? Would I not 
have to worry about the CZ losing patches for atleast a few years?

It's quite an investment to buy 1400mA nicd batteries for both my 
cz's, so I'd love to hear your opinions about it.

Brian.

You should read up on NiCd charging techniques first.  Not that I'm any kind 
of expert but I think connecting directly to a power supply isn't the best 
approach.

Thanks, good thinking. I will have a look into that, when I found something
out I will post it here.

Scott and Brian,
  Do yourself a favor and don't install NiCad's anywhere near the 
circuit boards, they leak. The newer NiMh batteries are a much better 
choice. They don't have memory and they will take a lot of abuse 
before they leak. It should be okay to charge them so if you use the 
synth for a few hours it would hold the charge for up to several 
months. If you are only powering the memory maybe even years...

Thanks Narfman, I'll look for NiMh then.
 
I think it will work, but I have to find a way to step-down from 9 volts to
6 volts, that's the fault in my plan. I called my local electronics shop and
they said there are some ways to do that, but it kinda depended on some
factors. I'm too bad at electronics to figure out those ways by myself, but
said they'd help me out if I'd drop by after the weekend. 
 
Brian.

I need to do this mod asap -- great! 

But I'm confused by the above directions.

What is the point of using a 9v battery strap? Is there one? Isn't
that just a couple of wires with 9v connectors at the end? Why not
just wire the battery holder straight to the + and - terminals?

eh?

I don't know what the original poster meant, but I can think of 2
advantages to doing it the way it's described.

1. If you use a 9V battery snap, you will always have your choice of
powering it with a 9V or 4 x AA.

2. If you use a 9V battery snap, you will be able to remove the
battery block if you need to.  For example, some cases won't come
apart without taking off the battery block.  Some machines I have,
there's a gap into the battery compartment big enough to feed a 9V
snap through, but not big enough to feed a battery block through.

And of course they make nifty battery blocks that have 9V style snap
connections on them:

I don't know if that's the correct answer or not, but it's something
to think about.

meh. i guess it would be neat to be able to run it off batteries using
a single 9v battery instead of 6 D's...but i never run mine off
batteries and can't imagine where/why i would...

i just used aluminum foil and tape and some spare wires (and the 4
AA's) to make my battery pack...and taped it to the inside of the CZ
rather than putting it inside the battery compartment. i could always
wire a 9v battery snap into the battery compartment later..

but a friend says he's done this same trick, and only got a few weeks
of life out of the new battery pack before it died...!? i can't
imagine how the batteries could have drained so quickly tho...he ended
up having a lithium battery professionally installed...
