suitable for the environment in which it is located. The plug must be a miniature
phone plug.

supplied to mate with this connector. Remember, red is +, black is -! The power
cord is equipped with a fuse to protect the radio. Use only a six (6) AMPERE fast
blow fuse for replacement. Wire directly to battery for best result.

ly energized. This retains the scan memory and programmed priority channel. The
small amount of battery drain (3mA) caused by the continuous "ON" state of the
switch is insignificant and will not cause a battery drain problem. CAUTION! If
power is supplied through the ignition switch, the memory can be lost regardless
of .the position of the switch.
