Motorola SL300 用户手册

This activated microphone state is also known as “hot
mic”.

Note: Some accessories may not support “hot mic”.
Check with your dealer or system administrator for
more information.

If you press the PTT button during the programmed
hot mic transmission period, you hear a prohibit tone,
indicating that you should release the PTT button.
The radio ignores the PTT press and remains in
Emergency mode.

Note: If you press the PTT button during hot mic, and
continue to press it after the hot mic duration expires,
the radio continues to transmit until you release the
PTT button.

If your radio is set to Silent, it does not display any
audio or visual indicators during Emergency mode, or
allow any received calls to sound through the radio’s
speaker, until the programmed hot mic transmission
period is over, and you press the PTT button.

If your radio is set to Silent with Voice, it does not
display any audio or visual indicators during
Emergency mode when you are making the call with
hot mic, but allow sound through the radio’s speaker
when the target radio responds after the programmed

hot mic transmission period is over. The indicators
only appear when you press the PTT button.

Note: If the Emergency Alarm request fails, the radio
does not retry to send the request, and enters the hot
mic state directly.

1 Press the programmed Emergency On button.

The LED lights up solid green.

2 Once a tone sounds, speak clearly into the

microphone.
When hot mic has been enabled, the radio
automatically transmits without a PTT button press
until the hot mic duration expires. While
transmitting, the LED lights up solid green.

3 Once the hot mic duration expires, the radio

automatically stops transmitting. To transmit
again, press the PTT button.

Note: This feature is only applicable to the radio
sending the Emergency Alarm.
