TS 940 Battery Replacement
Digital A Board
Once you get the speaker and control panel removed, then remove the cover for the digital A board housing. This image shows the old battery removed and the pins cleaned up for the replacement. The spacing between the pins is 1.300" and the pin on the left (viewed from the operator's position) is positive.
The replacement batteries from Batteries Plus. They are CR2430's with 1.000" solder tabs welded to them. I punched the terminal holes later with a tiny diameter paper punch. The batteries cost $6.50 for the pair
The completed installation. Note the Piexx RS232 interface board.
Sub Display Battery
When you start seeing displays like this, start getting suspiscious of the battery on the back of the assembly
After removing the top and bottom case covers, you prop the front of the radio up 1 to 1 1/2 inches. The loosen the bottom two screws that hold the face on and remove the top 2. The display will tilt out so you can work on it. In this shot you can see the "Voice board" mounted up on top of the chassis. This radio uses the single battery, CR2430
Here is the display after being removed and prior to battery replacement. You really don't have to remove the assembly. I had to take the unit to Batteries Plus to ID the coin cells. Most radios will have a single battery, this one had two and a soldered in diode on the top one. This radio used CR2032 cells
