Switch and Connectors
connectors. The cables are color-coded-white
for XMIT, yellow for RCV. Identically-colored
dots are located on the electronics housing
adjacent to these connectors. Be sure that
each cable is attached to the proper probe
connector.
When the fiber optic cables are not attached,
always cover the probe connectors with the
protective plastic covers supplied with the
unit, or with similar material. This prevents
dirt or other contaminants from entering the
connector and causing communication
problems.
ARM/OFF
The ARM/OFF switch activates and
deactivates the probe. In the ARM position,
the probe is powered by its internal 3.6 VDC
NiCd battery: in the OFF position, the probe is
inactive. To prolong battery life, set the
ARM/OFF switch to OFF at the end of a test
sequence or when the probe is not in use.
