The selections are:

 CALL: calls back the caller (set individual call to the caller).

 DELETE: deletes the call record.

 CANCEL: cancels the action selection.

The selection is made with the▼ and ▲ keys.

The “Menu” or “Back” key returns to Stored Calls screen.

A “Reset” function key press (if configured) takes the radio back to the default screen

display.

If “DELETE” is selected, pressing “OK” removes the selected call record (being viewed) from

the list. The radio returns to the Stored Calls Screen with the next record being displayed.

If “CANCEL” is selected, the Stored Calls screen is displayed.

If “CALL” is selected, pressing “OK” sets the radio to individual calling mode with the ID of

the stored call. A subsequent PTT within the configured time interval will send an individual

call to the ID of the stored call.

5.1.10 Transmitting

To avoid interfering with other users of the channel, listen first, or check that the speaker icon

is not present, to ensure no transmissions are occurring.

If the speaker icon is shown, there are transmissions present on the channel and the user

should not transmit. The radio may be programmed to prevent transmission on a busy

channel if required.

Hold the portable approximately10 centimetres from the mouth, press the PTT and note that

the TX-LED is RED. Wait for the grant tone, and then speak clearly across the face of the

microphone in a normal conversational manner.

In most systems it is important to wait a short time between pressing PTT and commencing

to speak. This ensures that the path is properly established and avoids lost or distorted

speech.

Use the correct operating procedure and keep transmissions short.

Release the PTT as soon as the message is finished.

The talk group for a transmission is usually associated with a channel selection. A talk group

will address all others that have the same TGID selected.

While on a P25 channel, the transmission will be P25 digital. For an analogue channel, the

transmission will be analogue FM.
