Can anyone Please help me out, I'm looking for a SERVICE Manual for the Motorola R2600 Test Set
The problem I have is after I replaced the battery on the Control Board and Replaced ALL the Electrolytic Capacitors on the Power Supply Board, The Unit came back to life, and it worked on
all functions except in Tracking Gene Mode. It worked fine in the 10Mhz and 25Mhz ranges, but when you pressed the more soft key as soon as you selected a range between 5Mhz and 100Khz the unit just locked up and the only way out of this was to de-power the unit from the mains.
I've since cleaned, checked and Buzzed out the ribbon cables, because only once when I re-seated the 3 going to the control board it started to work on the 5Mhz to 100Khz ranges. I then
de-powered it a few times and it came back every time. Then I used it in that mode for a few hours and it worked Ok. So I switched it off for a few hours and when I came back to it and turned it on, Yes you guessed it, it's no longer worked on those ranges as mentioned above.
I then left it for a few days, turned it on and it goes into auto Calibration and when it completes the screen goes blank and then the copyright notice flashes on and off as well as the red LED's for
Antenna & Gen out. I've checked all the voltage rails & all are OK as well as the 10Mhz Osc. It did on one occasion when I switched off and on it sprung back to life. But that was only once.
Everytime you switch it on now it goes into the self Cal Mode and then the flashing Copyright Screen and LED's.
Can anyone Please help me with a SERVICE Manual or other info on this one,
Many thanks in advance,
