locked. The precise lockout conﬁ guration is programmed

by your Authorized Vertex Standard dealer.

ARTS™

(

AUTO RANGE TRANSPOND SYSTEM

)

This system is designed to inform the operator when you

and another ARTS™-equipped transceivers and stations

are within communication range using the DCS Encoder/

Decoder.

During ARTS™ operation, when the radio receives an

incoming ARTS™ signal, a short single beep will sound.

If you move out of range for more than two minutes, your

radio senses that no signal has been received, causing a

short triple beep to sound. Moving back into communica-

tions range, a short single beep will again sound as the

ARTS™ signal transmission from another transceiver or

station is back in range.
