FREQUENCY/ALPHA ADJUSTMENT

frequency will be displayed. If the radio is in

SETTING THE SQUELCH SENSITIVITY
The sensitivity of the Squelch to incoming signals
can be set to suit your operating environment.
In quiet rural locations a low setting will allow
the weakest signals to be received while still
keeping the radio quiet between transmissions. In
city locations, a higher setting might be needed
to ensure the squelch remains closed when
subjected to the higher interference levels often
encountered in high density areas.
The TX4600 has ten (10) preset Squelch
sensitivity settings (labelled SQL-0 to SQL-9) that
can be selected using the Menu function. The
minimum Squelch setting (SQL-0) will open the
Squelch allowing all signals to be heard. SQL-9
is the maximum setting, requiring very strong
signals to open the squelch. The factory default is
SQL-3 which generally provides reliable squelch
operation for most applications.
To preselect the Squelch sensitivity
1. Select a Channel between 1 and 80.
2. Press and hold the MENU key until the radio
beeps. SQL-x will be displayed where x is a
number from 0 to 9.
3. Press the or key to increase or decrease
the preset squelch to the desired setting.
4. Press and hold the MENU key to store the
new setting.
SELECTING THE SCAN MODE
The TX4600 features two scan groups – Open
Scan and Group Scan.
NOTE:
If preferred, your dealer can re configure
your unit to have two Open Scan or two Group
Scan groups.
To select the Scan Group
1. Select a Channel between 1 and 80.
2. Press and hold the MENU key until the radio
beeps.
3. Briefly press the MENU key again. ‘OSCAN’
(Open Scan) or ‘GSCAN’ (Group Scan) will be
displayed.
NOTE:
If two Open Scan or two Group Scan
groups have been installed, SCAN1 or SCAN2
will be displayed.
4. Press the or key to select the required
Scan Group.
5. Press and hold the MENU key until the radio
beeps, to store the setting.
