After the batteries are installed, turn the power on by moving the Power Switch to either the 1 or Both position. The small red power-on LED(s) (see a at left ) should light (red light at 1 if Power Switch is in position 1; red light at 1 and 2 if Power Switch is in Both position) and the LCD window should come on. If this does not happen, the batteries are installed incorrectly or they are depleted.

The receiver’s “fuel gauge” battery indicator (see b at left ) displays a maximum of four bar segments. When LCD flashes “LOW.BAT”, the batteries should be replaced immediately to ensure continued operation. Note: Battery indicator is only visible in the “Hold” position.

Selecting Frequencies Overview…

on your Receiver 1. Turn the power on by moving the Power Switch to either the 1 position (for single-channel operation) or Both position (for dual- channel operation).

2. Switch the Dual-channel Control Switch to 1 (to set frequency for Receiver Channel 1) or 2 (to set frequency for Receiver Channel 2). Audio output is muted for the channel that is selected.

3. Press the Set button to enter the Frequency Selection Menu mode; the word “MENU” will appear.

4. Use the Up/Down arrows to cycle through functions: - first arrow up is Manual Frequency Selection mode; - second arrow up is Automatic Scan Group 1;

- third arrow up is Automatic Scan Group 2; - fourth arrow up is Automatic Scan Group 3;

- fifth arrow up is Quit, allowing exit from Menu mode.

Dual-channel Operation First…
