Replacing Batteries
Replacing Batteries
Your unit uses a battery with built-in protection that has been especially
designed for EXFO. For this reason, you can only replace the main battery
with a similar one.
You can purchase new batteries from EXFO.
To replace the main battery:
1. If you do not have a replacement battery, contact EXFO to purchase a
new one.
2. Turn off the unit.
3. Open the battery compartment door located at the top of the unit (turn
the cap counterclockwise and pull it away).
4. Replace the battery.
5. Close the battery compartment door.
Note: You cannot replace the clock battery yourself.
CAUTION
Use Li-Ion batteries of the same type and model only. Use of other
batteries may damage your unit and compromise your safety.
WARNING
Do not throw batteries into fire or water and do not short-circuit
the battery’s electrical contacts. Do not disassemble.
