additional features available with a control unit are a power turn-off delay and horn alert. The operation of the Remote Control Unit with this trans- ceiver is described in the following information.

Control Unit Controls

PWR - Turns both control unit and transceiver power on and off. Power is also controlled by the vehicle's ignition switch. Therefore, that switch must also be on to turn power on. The transceiver on-off switch and volume control are nonfunctional when the control unit is used.

VOLUME - Pressing the upper VOLUME switch increases the volume level by one step, and pressing the lower switch decreases the volume level by one step. Holding either switch down causes the function to repeat. The volume level is indicated by a bar graph on the right side of the display.

NOTE: The equivalent transceiver key is shown in parentheses in the following descriptions.

SYSTEM (S) - Pressing the upper SYSTEM switch increases the selected system number by one, and pressing the lower switch decreases the selected system number by one. Holding either switch down causes the function to repeat. The selected system is indicated in the display above the switch.

GROUP (G) - Functions like the SYSTEM switch to select the desired system.

SCAN (SCN) - Turns scanning on and off. Scanning is on when “SCN” is indicated in the display.

LOCK (LCK) - Locks systems and groups out of the scan sequence. The lockout indicator is the word “LOCKOUT” in the display. Small arrows on either side of this word indicate if the system and/or group is locked out.

P1 (PHON) - Turns the phone mode on and off.
