Talking And Monitoring; Receiving A Call; Signal Strength Indicator And Channel Busy Indicators - Motorola RDU4160d User Manual

TALKING AND MONITORING

It is important to monitor for traffic before transmitting
to avoid 'talking over' someone who is already
transmitting
To monitor, long press and hold the SB1(*) button to
access channel traffic. If no activity is present, you will
hear 'static'. To release, press SB1 again. Once
channel traffic has cleared, proceed with your call by
pressing the PTT button. When transmitting, the LED
Indicator stays solid red.
• To listen to all activity on a current channel, short
press the SB1 to set the CTCSS/DPL code to 0.
This feature is called 'CTCSS/DPL Defeat
(Squelch set to SILENT)'.
• (*) This assumes SB1 is not being programmed
for a different mode.

RECEIVING A CALL

1. Select a channel by rotating the Channel
Selector Knob until you reach the desired
channel. An audible voice indicates the
selected channel.
2. Make sure the PTT button is released and listen
for voice activity.
3. The LED Indicator stays solid red when the
radio is receiving a call.
4. To respond, hold the radio vertically 1 to 2
inches (2.5 to 5cm) from mouth. Press the PTT
button to talk; release it to listen.
SIGNAL STRENGTH INDICATOR AND
CHANNEL BUSY INDICATORS
When there is activity on a frequency, the radio
displays the Signal Strength Indicator icon and the
radio LED blinks faster. When your radio is receiving
(Rx) and there is activity on the same frequency and
code as your radio, the radio Signal Strength Indicator
icon can change from 1 (weakest) to 6 (strongest)
depending on the radio reception coverage. This
helps you to determine if your radio is moving out of
range.
Note: Obstacles blocking the signal path affects
the strength of incoming signal.
