Basic Operation; Main Function Operation - Retevis Rt56B Bedienungsanleitung

Basic Operation

Power On
Rotate [PWR/VOL] control button in clockwise direction to power on, and a beep prompt tone.
Volume adjustment
Press Monitor Key [MONI], while rotate [PWR/VOL] to adjust volume.
Transmit/Receive
If want to call out, press [PTT] key, red indication light on, speak on the microphone with normal volume.
Release [PTT] Key, enter the receiving state.
Notice: Keep lips 3~5cm away from microphone.
When transmitted, red indication light on.
When received, green indication light on, and mic worked.
Signal Monitoring
For weak signal or channel with CTCSS/DCS, long press monitor key [PF1] to monitor signal. long press monitor
key [PF1] again to shut down monitor signal.
Torch Light Function
Long press [PF2] key to enter torch light mode, long press [PF2] key again to shut down torch light function.
FM Radio Function
Long press [PF1]and [PF2] simultaneously to enter FM radio status; press [PF1] key to upward seek radio
station, and press [PF2] key to downward seek radio station. There are 16 FM channels, and must program the
FM channel frequency by PC programming software.

Main Function Operation

Scanning Function
Scanning function can be selected for multiple channels for rotation monitoring, receiving signals from multiple
frequency points. Two scan mode selection (CO-Carrier Scan/TO-Time Scan).
Turn on/off Scanning: short press keys [PF1] and [PF2] simultaneously to enter channel scan. Short press keys
[PF1] and [PF2] simultaneously again return to standby channel.
In channel scanning mode, press [PTT] to end scanning, and it will go on transmitting.
CO—Carrier Scan: Stop scanning when detects a signal until signal vanishes. Restart scanning
after signal vanishes for 5 seconds, unless new signal detected during delay time.
TO—Time Scan: Stop scanning when detects a signal. Stay for 5 seconds then go on scanning, even signal
exists.
CTCSS Function
When the channel opens the CTCSS decoding function, the received signal can be filtered. Only when the
transmitter and receiver set the same CTCSS, the receiver will open the speaker to make sound.
Remote Stun/Remote Kill Function
DTMF signaling codec technology is used to control the two-way radio remotely and make it enter the state of
remote stun/remote kill, which can prevent the loss of the two-way radio from being monitored by others during
the use of the two-way radio.
Operation Method: The remote stun/remote kill signaling and on/off are set by PC programming software in
advance, and then the main control party can launch the remote stun/remote kill signaling by pressing [PTT] key,
and the charged party can be remote stun/remote kill.
When remote stun status, press [PTT] cannot transmit with a beep prompt tone.
When remote kill status, it is forbidden to transmit and receive simultaneously, all keys are invalid, flash orange
light every 30 second and a beep prompt tone.
In case of remote stun/remote kill, please contact the product dealer in time.
Transmit 1750Hz signal
Press [PTT] to transmit, in transmit status, press [PF2] key to transmit 1750Hz, end transmit until release [PF2]
key or [PTT] key.
VOX function
VOX function that is through the voice control of the radio transmission, can release hands.
When the VOX function is turned on, you can speak directly into the microphone without pressing the [PTT] key.
The two-way radio will automatically transmit, and the two-way radio will automatically stop transmitting when
you stop speaking.
Speech volume should be appropriately large, more than a certain value will be launched automatically.
