Auto-Range Transponder System
The Auto-Range Transponder System (ARTS) is an
analog-only feature designed to inform you when your
radio is out-of-range of other ARTS-equipped radios.
ARTS-equipped radios transmit or receive signals
periodically to confirm that they are within range of
each other.
Your radio provides indications of states as follows:
First-Time Alert A tone sounds.
ARTS-in-Range
Alert
A tone sounds, if programmed.
ARTS-Out-of-
Range Alert
A tone sounds. The red LED
rapidly blinks.
Note:
Check with your dealer or system
administrator for more information.
Over-the-Air Programming
Your dealer can remotely update your radio via Over-
the-Air Programming (OTAP) without physical
connection. Additionally, some settings can also be
configured via OTAP.
When your radio undergoes OTAP, the green LED
blinks.
When your radio receives high volume data:
• The channel becomes busy.
• A negative tone sounds if you press the PTT
button.
