may be necessary to obtain full capacity.
Repeated charging, operating and storage in extreme temperatures may effect battery life.

The Battery is user-replaceable without the need for re-calibration. Extra batteries are available from your
EXFO representative (CSK-BATT2). Accompanying the battery will be instructions for replacing and
charging. The CableSHARK has been designed such that the user can change the battery easily with very
few tools. Extra batteries are available from your EXFO representative. To change the battery, locate the
battery compartment door on the underside of the unit.
Please note that any stored data in non-volatile RAM will not be lost by changing the
rechargeable battery.
After removing the two slotted screws from the battery cover, the cover must be carefully pried; with the
slotted screwdriver ; to loosen and release the sealing tape between the cover and the battery. Note: The
battery is friction fitted into the battery compartment. Once the battery cover has been removed, the battery
can be removed from the battery compartment by placing ones hand over the battery, turning the unit so the
display is facing upwards and then gently tap the CableSHARK against the same hand. Once the battery is
freed from its compartment, the black connector with the flying clip must be removed from the small slot in
the battery compartment. The black clip is then pressed to release the male and female connector.
To reinstall the battery, the mating connectors are latched in place with the retaining clip. Carefully insert the
