[H/L] KEY

On the Marine Band, changes the transmitter output power between High (5 Watts), Medium (2.5 Watts), and Low (1 Watt). Does not operate on “Low power only” and transmission-inhibit channels.

When operating on Canadian channel 13, or USA channels 13 or 67, pressing this key momentarily toggles the power level from Low power to medium or High power.

Secondary use:

Hold down this key to lock the keypad (except the PTT, SQL, and [H/L] keys) so that they are not accidentally changed. The key lock symbol “” will appear on the LCD, to indicate that the functions are locked. Hold down until the key lock symbol “” disappears to unlock the radio.

[SCAN] KEY

Starts scanning and priority scanning of programmed channels. When scanning, press and hold this key to turn on and off priority scan (“P” is shown on the display during Priority scanning).

[PRESET] KEY

Immediately recalls one of up to 10 user preset memories for each band (shown as 0-9 on the LCD). Pressing this key repeatedly scrolls through the preset memory channels.

[MEM] KEY

Press this key to memorize the selected channel for scanning. When pressed a “MEM” icon will be shown on the LCD display indicating the channel has been saved to scan memory. The scan memory is only used with the Marine and WX channels.

To delete the channel from scan memory, select the channel and press this key until “MEM” is removed from the display.

BUSY/TX INDICATOR

This indicator glows green when a signal is being received and red when transmitting.

When the Emergency feature is activated, this indicator blinks the internationally -recognized Morse Code “S.O.S.” message.
