FRONT PANEL DESCRIPTION

ANTENNA LEADS - These BNC terminated leads provide isolated RF signals for each receiver installed in the

system.

ANTENNA - The helical antenna provided with the unit attaches to this BNC connector directly with a twist lock

motion. Other 50 Ohm antennas designed for the VHF high band may also be used.

POWER SWITCH - The power switch has three positions. The OFF position turns off power to all modules in the

system. The MAIN/EXT position activates the system and draws power from the gel-cell batteries located in the

bottom of the system or from an external 12 Vdc power source. This power is distributed to all receivers installed

in the system. The INT 9V position activates the CDM4 module only, drawing power from the CDM4’s internal 9v

battery.

EXT LED - This LED will light when power is provided from an external 12 Vdc power supply.

12V LED - This LED indicates operation from the internal gel-cell batteries.

CHARGING LED - This LED lights when the gel-cell batteries are being charged with the CH-50 charger. It will

extinguish when the batteries achieve full charge.

AC LED - This LED indicates the unit is plugged into AC with the CH-50 charger. It remains on as long as the

charger is connected, regardless of the battery charge state.

INSTALLATION SCREWS - These screws are used for receiver installation and removable. See page 5 for further

instructions.
