Owner Manual Conventions

To indicate a key, button, knob or other physical control, we print the label in BOLD UPPER CASE. To indicate an LCD (display) label, option, or selection, we use UPPER or Lower Case italic labels such as MENU, 5 Seconds, etc.

You will also occasionally see an option labeled as (default). This means that the option is set in the manner indicated at the factory and is the setting when you first apply power. If you choose not to alter it, the default is the setting used by the radio.

Indicator Sounds

The radio sounds several tones designed to convey important information. Become familiar with them to use the radio more effectively.

Power On — a rapidly rising tone sounds to confirm that power is applied.

Keypad Touch Single Tone — sounds to confirm you have pressed a single key

Keypad Touch Double Tone — sounds to confirm you pressed and held down a key for 2 seconds.

Error Tone — sounds to indicate an invalid key press or operation.

PTT Error Tone — sounds to indicate an invalid press of the PTT switch.

WX ALERT Tone — a rising and falling tone sounds when a weather alert is received and decoded.

PTT Time Out Tone (PTT Error Tone) — sounds when your continuous transmitting time exceeds 5 minutes. Also sounds if you attempt to transmit with low power battery. If the battery icon continues to blink once you stop pressing the PTT key, you must recharge/replace the currently installed battery(s)
