Changing the Battery in a T-60
Follow these steps to change the battery for the non-volatile RAM in a T-60:
1. Save the contents of the program memory. Use a PC and the
ApplicationBuilder program to do this. Changing the battery may reset
the system if you wait too long to change it or don’t change it quickly,
thereby erasing the contents of all memory.
2. Remove power connections to the unit.
Disconnect power from the T-60 before attempting to change the battery.
Hazardous voltages exist inside the unit with power connected. Personal
injury or death may result if the power is not disconnected.
3. Carefully unscrew the top two screws and each of the screws on the side
of the unit.
4. Lay the unit face down on a soft, clean surface.
5. Remove the rear cover by carefully lifting it off the unit.
6. Position the cover to the side of the unit, being careful not to stress the
internal cables.
7. To remove the old battery, insert a small screwdriver between the edge of
the battery and the battery holder near the battery clip (see diagram).
Push gently and the battery should slide out.
8. Before installing the new battery, press down on the battery clip to make
sure that there will be good retention force when the battery is in place.
Also make sure that all contact surfaces are clean. As noted on the
battery clip, make sure that the positive (+) side of the battery is up.
Slide the battery under the clip and into the battery holder. Make sure
that the battery is held firmly in place.
Improper orientation of the battery will not allow the battery backed RAM to
function and your memory will cease to be non-volatile. However, this will
not damage the battery or the controller; just turn the battery over and
continue with the installation procedure.
