Uniden UH-057 manual Tone Calling, TX Selcall ID Format, Radios

Tone Calling

Tone calling enables you to selectively call other radios.

To do this, the SELCALL ID of the radio you are going to call should be in the Transmitters SELCALL ID memory (please see Programming Method on page 28).

To Call:

1.Select the channel where you and your group agreed to use for Selective Calling.

2.Press and hold the @ Key for about 1.5 seconds. One Long Beep will be heard and 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 had successfully made contact.

The Acknowledge Tone for the Sundowner UH-057 is a successive three Low Tone beeps.

Group Calling

Sundowner UH-057 has group calling capability. It can

either respond to a group call or transmit a Group Calling Code.

Group Calling enables you to call members of your group simultaneously. However, you need to follow a certain format on programming your TX SELCALL ID to do this.
