Connecting to a 12v Battery:
The PID-760 battery clamps allow quick hook-up to a 12V
battery. Make sure the PID-760 and the devices are turned
off.
1. Unscrew the positive (red) and negative (black) plastic
connector knobs from the back of the inverter.
2. Slip the end of the red (positive) battery cable clamp
wire over the red (positive) threaded extension and then
screw on the connector knob and tighten so the wire is
firmly attached. Repeat the same process for the black
wire.
. Connect the red (positive) battery cable to the positive
(+) battery terminal taking care to shield eyes, clothing
and hands from battery acid. Connect the black battery
clamp to negative (-) ground on the battery.
4. To disconnect the PID-760, reverse the above steps.
NOTE: A ''buzzing'' sound emitted from inexpensive
sound systems is the result of ineffective filters in the
sound system. This can be resolved by purchasing a
sound system with a higher quality power supply or
higher quality filter.
