When a call is received...

While on TSQ Condition, when UH-057 receives a code
matching your SELCALL ID, it will do the following opera

tion.

1. Automatically responds to the caller by transmitting

Acknowledge tones.

2. Informs you that a caller is on the channel by emitting a

CALL ALARM (three successive tones in a regular
interval for 10 seconds.) and displays the CAL indicator.

3. Flashes the TSQ indicator for about 20 seconds allowing

you to use the PTT Switch. If you will not be able to

respond within the 20 second period, TSQ stops flashing
and Quiet operation resumes.

Responding to a call automatically removes the channel

from “Quiet" operation. The TSQ and CAL indicators

disappear from the LCD display.

Tone Squelch Scanning

If you are using two or more channels on TSQ Mode, you

can monitor all of these channels for selective calls by using
the TSQ Scanning.

To use this feature:

1. Select any programmed TSQ Channel.

2. Press and hold the

switch for about

.5 seconds.

TSQ scanning starts and the SCN indicator appears on
the LCD display.

Unlike Normal Scanning, TSQ Scanning checks the

detected carrier for SELCALL information. If no information

is seen, TSQ scanning resumes.
