Recording:

The last 2 minutes of incom- ing audio will be stored on a first-in, first-out basis.

Playback:

Press (or Press and hold) the assigned Soft key to start playback. During playback, pressing then “#” key lets you jump forward 8 seconds, while press- ing the “￿” key lets you go back 8 seconds. To stop playback before the stored message is complete,

Encryption

When the Voice Scrambler feature is enabled, pressing the assigned Soft key of the “Encryption” toggles the Scrambler “on” and “off.”

ARTS (Auto Rande Transpond System : VX-420 only)

This system is designed to inform you when you and another ARTS-equipped station are within com- munication range.

During ARTS operation, your radio automatical- ly transmits for about 1 second every 55 seconds in an attempt to shake hands with the other station.

If you have out of range for more than two min- utes, your radio senses that no signal has been re- ceives, a ringing beeper will sound, and “IN RANGE” will appear on the LCD. If you subsequently move back into range, as soon as the other station trans- mits, your beeper will sound and “OUT RANGE” will

appear on the LCD.

DTMF Paging System (VX-420 only)

This system allows paging and selective calling, using DTMF tone sequences.

When your radio is paged by a station bearing a tone sequence which matches yours, your radio’s squelch will open and the alert will sound. The three- digit code of the station which paged you will be displayed on your radio’s LCD.
