Push-To-Talk (PTT) Button
The PTT button on the side of the radio serves two basic purposes:
•While a call is in progress,
the PTT button allows the |
|
radio to transmit to other | PTT |
radios in the call. | Button |
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 12).
Depending on programming, if the Talk Permit Tone 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 will 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 the Channel Free Indication tone if your call is interrupted, for example when the radio receives an Emergency Call.
You can turn off the Channel Free Indication tone by disabling all radio tones and alerts (see Turning Radio Tones/Alerts On or Off on page 24).
Switching Between Analog and Digital Mode
Each channel in your radio |
|
can be configured as an | Channel Selector Knob |
analog channel or a digital |
|
channel. Use the Channel |
|
Selector Knob to switch |
|
between an analog or a digital |
|
channel. |
|
When switching from digital to analog mode, certain features are unavailable.
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 16).
