Maintenance
Warning
To avoid electric shock, do not perform any
servicing other than that contained in the
operating instructions unless you are
qualified to do so.
Disconnect clips from any metallic
connections before performing any
maintenance.
Caution
Do not use CRC Cable Clean
®
or any similar
chlorinated solvent on the test set. Doing so
will damage the test set.
If moisture should get inside the test set, let the test set
dry at normal room temperature for 24 hours. DO NOT
HEAT THE TEST SET. Moisture can provide a leakage
path that may conduct hazardous voltages to you. DO
NOT USE the test set if wet.
Keypad Care
Daily use of your test set results in various liquids, dirt,
and other foreign material building up in your keypad.
The keypad may be cleaned by using a soft toothbrush
with soap and water. Do not use a petroleum-based or
chlorinated cleaning agent as it will harm the keypad.
Let the test set dry before use.
Replacing the Battery
Caution
Handling batteries should be done with
care. Do not allow the terminals to be
shorted together. Dispose of battery
properly to ensure contacts cannot short.
Disposal may be restricted by local laws.
To replace the battery (see Figure 3):
1
Turn the test set off.
2
Place the test set on a work surface, face down.
The work surface should be non-abrasive.
3
Using a Phillips screwdriver, remove the single
cover screw attaching the battery door cover to
the back of the test set.
4
Remove the battery door cover and the old 9 V
battery from the test set. Properly discard the
battery.
5
Insert a new 9 V battery. Make sure the polarity is
correct.
Note
Do not over tighten screw. Over tightening will
strip the plastic.
