ADVANCED OPERATION

be heard after the last key is pressed (the new code will now be transmitted).

The receiver squelch of the other station will be opened, and you can begin communication.

Speed Dial

Your Dealer may have pre-programmed Auto-Dial telephone number memories into your radio.

To dial a number, press the Dealer-assigned Soft key for Speed Dialing, then press the numbered key corresponding to the Auto-Dial memory number list provided by your Dealer. The DTMF tones sent during the dialing sequence will be heard in the speaker.

Emergency

The VX-900includes an “Emergency” feature which may be useful if you have someone monitoring on the same frequency as your transceiver’s channel. For further details contact your nearest VERTEX STANDARD dealer.

ARTS (Auto Range Transpond System)

This system is designed to inform you when you and

another ARTS-equipped station are within commu-

nication range.

During ARTS operation, your radio automatically

transmits for about 1 second every 25 seconds (the

interval is programmed by the Dealer) in an attempt

to shake hands with the other station.

If you move out of range for more than two min-

utes, your radio senses that no signal has been re-

ceived, a ringing beeper will sound, and "OUT OF

SERVICE" will scroll on the LCD. If you subse-

quently move back into range, as soon as the other

station transmits, your beeper will sound, and "IN

SERVICE" will scroll on the LCD.

DTMF Paging System

This system allows paging and selective calling, us-

ing 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 ringer will sound (unless you

have disabled it, as described previously).

The three-digit code of the station which paged you

will be displayed on your radio's LCD.
