Vertex Standard VX-820 18, ARTS, DTMF PAGING SYSTEM, LOCK

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, when the radio receives the

correct ARTS signal, a short beep will sound and the

“In” (meaning “In Service” notation will be displayed

on the sub-LCD. If you move out of range for more

than two minutes, your radio senses that no signal

has been received; three short beeps will sound, and

“Out” (“Out of Service”) will be displayed on the

sub-LCD. If you subsequently move back into range,

as soon as the other station transmits, a short beep

will sound and “In” will be displayed again on the

sub-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 will sound. The three-digit

code of the station which paged you will be displayed

on your radio’s LCD.

advertent transmission, various aspects of the

VX-820’s knob, soft keys, and PTT switch may be

locked.

The precise lockout configulation is programmed by

your Dealer.

To locked out the key locking, turn the radio off.

Now, press and hold the PTT and LAMP key while
