2.6. Replace Real Time Clock Battery
CR2032 coin cell is used for Real Time Clock backup power. The lifetime of the coin cell is around 5
years. If time cannot be stored, it may be caused by low battery.
To replace coin cell:
1. Unscrew two pieces screws and take them out. The exact locations are shown in the image
below.
Note: Be careful in handling the screws so they will not drop inside the bus validator.
2. Using a screw driver, take out the LTE board.
