Receiver Quieting

Puts the receiver in the "Ouiet" mode (also known as the "Tone Squelch" mode). When activated, the transceiver prevents any unwanted conversations

in the channel from being heard unless the call is specifically directed to you and the SELCALL ID required to open the "Ouiet" condition has been received.

To activate:

1.Select the channel you want to put in Quiet mode using the Channel Selector knob.

2.Press the T.SO button for about 1.5 seconds. One beep is heard and the T.Sa indicator appears on the LCD display. Under this condition, the PRESS- TO- TALK button is temporarily disabled. If you wish to use the same channel for normal communication simply remove the channel from Quiet mode.

Note: Channels that are stored in either OS or GS (MEM), when put in the Quiet condition, will be skipped during OS/GS Memory Scanning

If GS Scanning is used and the starting channel is a T.SO Channel, the PRI Channel will not be set. Rotate the channel knob to set a new PRI channel.

To deactivate the Quiet Condition:

1.Manually select the Tone Squelched Channel.

2.Press the T.Sa button for about 1.5 seconds. Two beeps are heard and the T.SO indicator disappears from the LCD display.

Call Receiving

While in the T.SO condition, when UH-099 receives a code matching your SELCALL ID, it will perform the following operations:

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 (Default Alarm Setting: four successive beeps in a regular interval for 10 seconds. Refer

to "Programming Method" for other alarm settings) and displays the CAL indicator.

3.Flashes the T.SO indicator for about 20 seconds allowing you to use the PRESS-TO-TALK button. Ifyou are not be ableto respondwithin the 20 second period, T.SO stops flashing and Quiet mode resumes.

Tone Squelch Scanning

If you are using two or more channels in the T.SO mode, you can monitor all of these channels for selective calls by using the T.SO Scanning feature.
