3. HAIL CONNECTOR--The speaker used for the hail function is plugged into this
jack. The speaker may be either four or eight ohms impedance and should be
suitable for the environment in which it is located. The plug must be a miniature
phone plug.
4. DC POWER CONNECTOR--Battery
connections are to be made with the cable
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.
5. ANTENNA CONNECTOR--This connector
is for connection of the antenna. A
type PL259 connector is required to make proper connection.
6. MEMORY SWITCH--When this switch is "ON", the microprocessor is continuous-
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.
