Operation - Special Features

Selective Calling

Selective Calling (Selcall) is a special Sequential Tone Squelch System that allows the
user to receive/transmit calls selectively from/to an individual or group, on a shared
busy channel. Therefore Selcall is a group feature used by groups with similarly set up
radios.
The UH8080NB has a Selective Calling system. Exceptional features, like 10 Selcall ID
Memories, Receiver Quieting, Tone Squelch Scanning, Tone and Group Calling make
the UH8080NB superior to other transceivers in its class.
Receiver Quieting (Tone Squelch)
When activated on individual UHF-CB channels (except for emergency CH05 and
CH35), it automatically mutes the receiver audio circuit of the radio. It will stay in this
Quiet mode as long as the Selcall tone code (Selcall ID) required to open the muting
circuit is not received.
Call Alarm
When a received code matches to your Selcall ID, an alarm (CA Alert) will be emitted
informing you that a caller is on the channel.
Tone Squelch Scanning
Scans only tone squelched Channels.
Tone Calling
Allows you to selectively call another radio. Up to 10 Selcall IDs can be stored for for
frequently called radios.
Group Calling Capability
Transmits Group Calls.
