External Power Installation
The HERMIT 2000’s internal lithium battery pack is designed to sup-
ply the instrument and its connected transducers with clean, reli-
able power for several years. You can extend the life of the battery
pack by using the external power accessories supplied with your
HERMIT 2000 whenever it is convenient. The HERMIT 2000 will
automatically switch over to external power when it is present and
will automatically switch back to its own internal battery pack if the
external power source is disconnected or depleted.
Cigarette Lighter Adapter
The cigarette lighter adapter allows the HERMIT 2000 to tap into
the 12 VDC battery of most vehicles. Use only with vehicles employ-
ing a 12 VDC negative ground system. Some vehicles require that
the ignition switch be left in the “ON” or “ACC” (accessory) position
for proper operation of the cigarette lighter.
To connect the cigarette lighter
adapter:
1. Connect the lighter adapter to
the External Power port of the
HERMIT 2000.
2. Remove the car’s cigarette lighter
and install the adapter in the
socket. Turn the car’s ignition
switch to “ON” or “ACC” if re-
quired.
3. Wake the HERMIT 2000 to con-
firm that external power is prop-
erly connected.
Warning
Use only the external power accessories provided with your
instrument. Connection of an improper power source could
cause permanent damage to the instrument and the trans-
ducers connected to it.
