IMPROVED AUDIO FEATURES
Low Level Expansion (LLE)
The LLE feature of your radio improves voice quality
by reducing unwanted background noise when
receiving a message.It is compatible with most
major types of audio processing systems available
today.
Companding
Companding is a feature that allows further
improvement of voice quality. It compresses your
voice at transmission, and expands it when
receiving while simultaneously reducing extraneous
noise. However, to enjoy this benefit, ALL
transmitting and receiving radios must have this
feature activated.
NOTE: Contact your dealer for your radio’s current com-
panding settings or to change the settings.

RADIO CALL INFORMATION
Emergency
Your radio can be programmed to emit an
emergency siren.The Emergency Siren will cause
the radio to sound a repetitive tone at the maximum
volume.
1. Press and release the Emergency button to ini-
tiate an Emergency Siren.
2. Press and hold the Emergency button to cancel
the Emergency Siren.
3. Press and release the Emergency button to
restart the Emergency sequence.
Talkaround
In your communications network, you may be using
a repeater to cover a larger area than what is
possible with your radio. However, you can
communicate with another radio within your radio’s
range without going through the repeater by using
the
Talkaround feature.This is especially useful
when the repeater is down.
Press the programmed Repeater/Talkaround
button to toggle between the options of making or
not making a call through the repeater. A positive
indicator tone indicates that the radio is in
talkaround mode, while a negative indicator tone
indicates that the radio is in repeater mode.
Squelch
If a particular channel receives many unwanted calls
coming from radios that do not belong to your
communications group and are some distance away,
or the “background noise” is excessive, you can try
to filter these transmissions out by tightening the
channel’s squelch. However, tightening squelch
could cause calls from members of your
communications group that are farther away to be
filtered out as well.To set the squelch level:
Press the programmed Squelch button to toggle
between the options of having normal squelch or
tightening the squelch of your radio. A positive
indicator tone indicates that the radio is operating in
tight squelch, while a negative indicator tone
indicates that the radio is operating in normal
squelch.
