HI FOLKS,CAN ANYBODY HELP ME OUT WITH A SERVICE MANUAL OR AN OWNERS MANUAL FOR THESE RADIOS? (PREFERABLY IN ENGLISH)
RANGER 2900,SOMMERKAMP TS789DX OR GALAXY URANUS? ALL ARE THE EXACT SAME ,JUST WITH DIFFERENT NAMES. I HAVE ALREADY CONTACTED RANGER & GALAXY THEMSELVES,BUT THEY SAID THAT THEY DONT HAVE ANY INFORMATION ON THESE RADIOS AS THEY ARE OLD,ALSO DOES ANYBODY KNOW IF THERE IS A BATTERY OR SOMETHING INSIDE THIS RADIO TO POWER THE MEMORY FEATURE? AS EVERYTIME I TURN THE POWER SUPPLY OFF IT WIPES OFF ALL THE MEMORIES I HAVE PROGRAMMED INTO IT, I HAVE LOOKED INSIDE THE RADIO, BUT NO SIGN OF A BATTERY.ANY HELP MUCH APPRECIATED,CHEERS
P.S THE I.D PRINTED ON THE MAIN PCB IS EPT630011Z.

The battery is on the back side of the display about the size of a computer battery and looks the same. Just below is a good review and history of the 2900.
