Rapidly blinking yellow – Radio is actively searching for a new
site.
Solid green – Radio is transmitting.
Blinking green – Radio is powering up, receiving a non-
privacy-enabled call or data, or detecting activity over the air.
Rapidly blinking green – Radio is receiving a privacy-enabled
call or data.
NOTE: While in conventional mode, when the green LED
blinks, it indicates the radio detects activity over the air.
Due to the nature of the digital protocol, this activity
may or may not affect the radio's programmed channel.
For Capacity Plus, there is no LED indication when the
radio is detecting activity over the air.
Upon a PTT button press, if the radio is programmed
for polite operation, the radio automatically determines
whether a transmission is permitted via a Talk Permit or
a Talk Denial tone.
Audio Tones
Alert tones provide you with audible indications of the radio’s
status or the radio’s response to data received.
Continuous Tone A monotone sound. Sounds
continuously until termination.
Periodic Tone Sounds periodically depending on the
duration set by the radio. Tone starts,
stops, and repeats itself.
Repetitive Tone A single tone that repeats itself until it is
terminated by the user.
Momentary Tone Sounds only once for a short period of
time defined by the radio.
