Motorola Solutions Inc. 89FT5803 ユーザーズマニュアル

In the United States, FCC regulations 
require you to monitor the conven-
tional channels before sending a call. 
The monitor feature can be accessed 
through one of your programmable 
buttons.

•

If the mode-busy feature is enabled, a 
blinking red LED on receive (PTT button 
released) indicates that the mode is cur-
rently busy.

•

If a mode is programmed for receive only, 
any attempt to transmit on that mode will 
cause an invalid-mode tone to sound until 
the PTT button is released.

This feature is programmed by your authorized 
Motorola dealer.

The “failsoft” system ensures continual radio 
communications capability during a trunked 
system failure. Your radio will automatically go 
into failsoft operation, if the central trunking 
controller fails for any reason. While in failsoft 
operation, your radio will transmit and receive 
on a predetermined frequency on a 
conventional mode. When the trunked system 
returns to normal operation, the radio will 
automatically leave the failsoft operation and 
return to trunked operation.

During failsoft operation,

Turn your radio on.

Adjust your radio’s volume.

Use the Mode Selector knob to select the 
desired trunked talkgroup or conventional 
channel.

•

Make sure the PTT button is released.

Listen for voice activity. The LED indicator 
flashes green when your radio is receiving.

You will hear a faint “beeping” sound every 
ten seconds.

Your radio becomes unsquelched.
