Improving Your Radio’s
Reception (Squelch)
Your radio will normally be programmed to minimise
unwanted noise or interference from other channels
(known as ‘squelch’). Without squelch, the radio would
‘chatter’ on and off in low signal strength areas.
However, it may sometimes to be necessary to adjust the
squelch settings when you are having difficulty hearing
a call, or when entering a low signal strength area.
Your radio provides two means to adjust the squelch
(noise and interference) levels: squelch override, and
squelch ‘city’ and ‘country’ preset settings.
Selecting a Factory Setting (City or Country)
There are two preset squelch settings: city and country.
The city setting is designed for high signal strength areas
and minimises noise and ‘chatter’ on a channel.
The country setting is designed for low signal strength
areas, and allows the radio to pick up more channel
activity.
To choose a squelch setting:
1 Long press the menu key to enter menu mode (if the
radio displays a submenu option, press the clear key
to enter the main menu).
2 Scroll through the main menu options using the
arrow keys until
USER SETTINGS is displayed.
3 Scroll through the user setting menu options until
SQUELCH is displayed (the radio will display CITY or
COUNTRY
as the current setting).
4 Short press the menu key to select CITY or COUNTRY .
5 Long press the menu key to exit menu mode.
