Power Source - Whistler HIGH SURGE POWER INVERTERS Owner's Manual

The Power Source.
When the engine is off, most batteries will provide ample power
supply to the inverter for one to two hours. The actual length
of time is a function of several variables including the age and
condition of the battery, the number of batteries and the power
demand being placed on it by the equipment being operated
with the inverter. If you are using the inverter while the engine
is off, we recommend you start the engine every 30 to 60
minutes and let it run for at least 10 minutes to recharge the
battery. We also recommend that the device plugged into
the inverter be turned off before turning over the engine.
Although it is not necessary to turn off the inverter when turning
over the engine, the inverter may momentarily cease operation
as the battery voltage decreases. When the inverter is not
supplying power, and turned on, it draws low amperage from
the battery (see specifications).
For You Television Fans & Audiophiles.
Although the inverter is shielded and filtered to minimize signal
interference, some interference with your television picture
may be unavoidable, especially with weak signals. However,
here are some suggestions that may improve the reception.
1. First, make certain that the television antenna produces
a clear signal under normal operating conditions (i.e.,
at home plugged into a standard 110 AC wall outlet).
Also, ensure that the antenna cable is properly shielded
and of good quality.
