Line Cords
The test has a field replaceable line cord. See
“Replacing the Line Cord” on page 15. The line cord is
attached through a rubber strain relief at the
transmitter end of the test set. Several different
configurations of line cords are available. See
“Accessories” on page 17 for model numbers.
Battery
W
Caution
Use caution when handling batteries. 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.
The test sets battery compartment makes battery
replacement easy. See “Replacing the Battery” on page
14.
Note
If the test set fails to operate properly, first
replace the battery and retest before sending
the test set in for repair.
A 9 V alkaline battery must be installed for the test set
to operate. Do not use rechargeable batteries. The
battery performs two main functions:
•
It powers the test set when on-hook.
•
It supplies supplementary current to the speaker (if
on) when the test set is off-hook.
The speaker draws more current than any other circuit
in the test set. It follows that the battery will last longer
if the speaker is used in moderation.
