Replacing Batteries
Replacing Batteries
Your unit uses batteries with built-in protection that have been especially
designed for EXFO. For this reason, you can only replace the main battery
with a battery designed for your FTB-1.
You can purchase new batteries and empty battery compartments (also
known as “battery covers”) from EXFO.
The main lithium-ion battery is offered in two sizes:
A four-cell (small) battery
An eight-cell (large) battery
Note: Since the battery must fit in the battery compartment, these compartments
are also offered in two sizes.
Note: Batteries and battery compartments are sold separately, which means you
can purchase extra batteries to use with a battery compartment that you
already have. The size of the battery must match the size of the
compartment.
To remove the main battery:
1. Turn off the unit.
2. Remove the battery compartment (located next to the module) as
follows:
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.
