Appendix A–8
REPLACING PARTS
This section provides information on replacing parts, including
fuses, the battery, printer paper, and print cartridges.
REPLACING FUSES
Repair or replacement of fuses should be performed only by
qualified service personnel (Troxler Service Representatives).
REPLACING THE LITHIUM BATTERY
The oven uses one DL2450 3-volt lithium battery (Troxler PN
15706) to maintain the stored data and real time clock. The oven
monitors the battery voltage. If the battery voltage is low, the oven
displays a “low battery” symbol on the default screen. To avoid
oven memory loss, replace the battery at least once a year.
WARNING
Carefully note the polarity of the battery when installing
it in the battery holder. A battery may explode or leak if
installed improperly.
The battery holder is located on the back of the electronics module.
To replace the lithium battery:
1. Turn the oven circuit breaker/power switch off.
2. Remove the four Allen-head socket screws that attach the
electronics module and bezel to the front of the oven.
3. Remove the bezel and set it aside.
4. Carefully remove the electronics module from the oven. The
cables attached to the module do not need to be disconnected.
5. Locate the battery access hole and battery cover on the back of
the electronics module. Remove the battery cover and remove
the old battery.
