VX-2500 OPERATING MANUAL Page 11 ADVANCED OPERATION ARTS (Auto Range Transpond System) This system is designed to inform you when you and another ARTS-equipped station are within communication 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 minutes, your radio senses that no signal has been received; a ringing beeper will sound, and "OUT OF SERVICE" will scroll on the LCD. If you subsequently 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 (Requires the optional FVP-25 Encryption/DTMF Pager Unit) This system allows paging and selective calling, using DTMF tone sequences. [. . . ]
