Motorola MOTOTRBO SL300 Portable 2-Channel Analog/Digital 2-Way Radio (UHF Band, No Display) - Manuel (Page 23)

Push-To-Talk Button
The Push-to-Talk (PTT) button serves two basic purposes:
• While a call is in progress, the PTT button allows the
radio to transmit to other radios in the call. 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.
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 hear a continuous Talk Prohibit Tone if your call is
interrupted. You should release the
PTT button if you hear
a continous Talk Prohibit Tone.
On/Off/Information Button
The On/Off/Information button at the top of the radio
serves three basic purposes:
• to power the radio on or off.
• to check the battery strength.
• to check the Received Signal Strength Indicator (RSSI)
signal strength when the radio is powered on.
