UNIDEN Model uh015sx UHF CB Radio
Selective Calling
20
Tone Squelch Scanning
If you are using two or more Channels in the TSQ mode, you can monitor all of these
Channels for selective calls by using the TSQ scanning feature.
To use this feature start the TSQ Scan by pressing and holding /TSQ for 2
seconds during Open Scan or Group Scan.
Unlike Normal Scanning, TSQ scans and checks detected signals for Selcall
information. If this information is not found, TSQ Scanning resumes.
When a call is received during TSQ Scanning, uh015sx follows the same response as
when receiving a call on a Tone Squelch Channel.
It differs only in the following ways:
1. If the call is not answered within 20 seconds, TSQ Scanning resumes.
The CAL icon remains on the LCD display.
To look for the Channel where the CALL is received.
a) Cancel TSQ Scanning by pressing .
b) Using the Channel Selector, browse through the TSQ Channels. The CAL
indicator marks the Channel where the Call is received.
2. When answered, TSQ Scanning is automatically deactivated. The Channel is
removed from the QUIET Operating Mode.
To deactivate TSQ Scanning:
a) Press and hold /TSQ for 2 seconds.
The unit returns to Normal Scanning Mode.
b) Press .
The whole scanning operation is cleared.
c) When a Selcall is received, press the PTT button.
The chance of receiving and decoding Selcalls effectively during TSQ
Scanning can be increased in many different ways. You can either
decrease the number of channels to be scanned thus increasing the
scanning speed – or – change some of the Selcall parameters (refer to
‘Selcall Programming’).
Tone Calling
Tone Calling allows you to selectively call other radios.
To do this, the Selcall ID of the radio you are going to call should be in the transmitter’s
Selcall ID memory (refer to '5/6 TX Tone Selcall Programming’ page 21).
To Call:
1. Select the channel that you and your group agreed to use for Selective Calling.
2. Press and hold for 2 seconds.
A beep tone will be heard and the CAL indicator will appear on the LCD display
while the Selcall ID is being transmitted automatically.
An acknowledge tone coming from the called radio will be received if you have
successfully made contact. The acknowledge tone for the uh015sx is a succession of
three low tone beeps.
