UNIDEN Model uh015sx UHF CB Radio
Selective Calling
Outline
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.
The uh015sx has a Selective Calling system. Exceptional features, like Receiver Quieting, Tone Squelch Scanning, Tone and Group Calling make the uh015sx superior to any transceivers in its class.
Receiver Quieting (Tone Squelch)
When activated, 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.
Group Calling Capability
Transmits and Responds to Group Calls.
Receiver Quieting
Puts the receiver in the QUIET mode (also known as the Tone Squelch mode). When activated, the transceiver prevents any unwanted conversations in the channels from being heard unless the call is specifically directed to you and the Selcall ID required to open the QUIET condition has been received. Under this condition, the PTT button is temporarily disabled. If you wish to use the same Channel for normal communication, simply remove the Channel from QUIET mode.
