Maintenance
Clean the case with a soft cloth dampened with water or a
mild soap solution.
Caution
To avoid damaging the case, do not use solvents
or abrasive cleansers.
Battery Life and Replacement
The toner and probe batteries last for about 20 hours of
typical use.
Figure 5 shows how to replace the battery in the toner and
probe.
Note
The position of the probe’s rotary switch when the
ba
t
tery is replaced enables or disables shield
validation for cable map tests. See “Validating the
Cable’s Shield” on page 10.
Warning
To avoid possible electric shock or personal injury:
Turn off the toner or probe and disconnect all test
leads before replacing the battery.
Use only a 9 V battery, properly installed in the
case, to power the toner and probe.
Caution
To avoid unreliable test results, replace the
battery as soon as the low battery indication
appears. See “Battery Status” on page 4.
