SDS9 start up problems
2007-09-26 by trevor_berner
Hi all, my first post to this user group, I have an SDS9 module which has been with me since new but only recently brought out of retirement after about 10 years of being locked away in a cardboard box. The problem I have is that at power on the unit flashes once (all leds and displays) and then the display flashes a single number 6 and then seems to shut down with nothing displaying and no leds luminated. I have replace the onboard 3.6 V battery but still the same, any ideas? Thanks for any help, Regards, Trevor
