Motorola XPR 5550 Switching Between Conventional Analog and Digital Mode, Push-To-Talk PTT Button

Page 19

Push-To-Talk (PTT) Button

The PTT button on the side of the microphone serves two basic purposes:

•While a call is in progress,

the PTT button allows the

radio to transmit to other PTT Button radios in the call.

Press and hold down PTT button to talk. Release the PTT button to listen.

The microphone is activated when the PTT button is pressed.

•While a call is not in progress, the PTT button is used to make a new call (see Making a Radio Call on page 22).

If the Talk Permit Tone (see Turning the Talk Permit Tone On

or Off on page 68) or the PTT Sidetone is enabled, wait until the short alert tone ends before talking.

During a call, if the Channel Free Indication feature is enabled on your radio (programmed by your dealer), you hear a short alert tone the moment the target radio (the radio that is receiving your call) releases the PTT button, indicating the channel is free for you to respond.

You will also hear a continuous talk prohibit tone, if your call is interrupted, indicating that you should release the

PTT button, for example when the radio receives an Emergency Call.

Switching Between Conventional Analog and Digital Mode

Each channel in your	Volume/Channel Knob	Scroll Up/Down
radio can be
configured as a
conventional analog or
conventional digital
channel.

To switch between an analog or a digital channel, use the

•Scroll Up/Down buttons, or

•Volume/Channel Knob, or

•programmed Channel Up or Channel Down buttons

When switching from digital to analog mode, certain features are unavailable. Icons for the digital features (such as Messages) reflect this change by appearing ‘grayed out’. Disabled features are hidden in the menu.

Your radio also has features available in both analog and digital mode. However, the minor differences in the way each feature works does NOT affect the performance of your radio.

NOTE: Your radio also switches between digital and analog modes during a dual mode scan (see Scan on page 32).
