Channel broadcast
(Factory setting: Off) After you set up this function via software, by
pressing the side key to select the channel broadcast key, the radio will
broadcast the current channel number.
10
Squelch level
(Factory setting: level 5) The noise reduction function is to strictly filter
out excessive background noise,eliminate or suppress background noise when no
signal is received, so that the speaker of the radio remains silent when no
signal is received. At this time, the noise reduction circuit is closed, and
when the noise reduction is turned on, the speaker sound will be heard. This
radio has a total of 10 squelch levels. The higher the level, the stronger the
noise suppression ability and the less likely it is to receive noise signals.
However, it may also miss out on weak signals that are useful to you.On the
contrary, the lower the level, the easier it is to receive weak useful
signals, but it is easily affected by noise signals.A level of ‘0’ indicates
that there is no noise suppression function and is the lowest level.Users need
to set appropriate squelch levels through programming software based on the
actual communication environment and requirements.
Cancel Squelch
(Factory setting: Short press side key 2) Press the side key to cancel the
squelch, close the squelch circuit, and forcibly turn on the mute.It is used
to monitor the transmission activity on the channel, and can be monitored
regardless of whether QT/DQT matches. Press this key again to exit this
function. Note: If there is no audio signal on the channel, listen to
background noise. If there is an audio signal, listen to the audio.
Scanning
(Factory setting: short press the side key 1) A listening method used to hear
calls from all channels.When the scanning function is activated, the radio
starts checking for active channel calls within the range.When there is an
activity, it will switch to this channel to answer the other party’s call
(whether the channel can be scanned is set by the programming software).If the
PTT key is pressed at this time, the channel will transmit a signal.Press the
side key for scanning function again or turn the channel knob to exit
scanning. Note: The status will not be saved the next time the radio is turned
on
11
Voice control switch(VOX)
(Factory setting: long press side key 3) This function allows you to transmit
through normal calls without pressing the [PTT] key,and to receive
transmissions when the call is stopped.Press the side key, and hear a “beep”
sound to indicate the VOX function is turned on.Press this key again, and you
will hear a “beep” sound to indicate the VOX function is turned off. And save
the next startup status.
VOX voice control delay
(Factory setting: 1.5 seconds) If the radio returns to receive mode
immediately after making a call, the end of the call may not be fully
transmitted.To avoid this issue, an appropriate delay time can be set so that
the call can be fully transmitted. But be careful not to set the delay time
too long. Range: 0.5 seconds to 3 seconds
Emergency alarm
(Factory setting: long press and hold side key 1) When a sudden emergency
occurs, the emergency alarm function can be activated,and the radio will emit
an alarm signal at maximum volume to remind others to pay attention.Press the
side key to activate the emergency alarm. At this time, the radio emits an
emergency alarm bell and an alarm signal.To turn off the emergency alarm
function, press the PTT key or turn off the radio to terminate the alarm.
Battery level speech
(Factory setting: short press side key 3) You can check the current battery
remaining capacity by pressing the side key to speech thebattery level. The
radios will speech the remaining percentage of the capacity.
12
CALL bell
(Factory setting: off)
When the side key is pressed for a call bell, a 2s ringtone is sent to inform
other radio users that one radio is calling them.
Companding function
(Factory setting: On) Adaptor the companding technology can significantly
improve the signal-to-noise ratio of the receiver, reduce noise during calls,
and make the speech clear. Note: This radio can be set to turn on or off the
companding function through programming software.
Voice scrambling
(Factory setting: Off)
When the scrambling is turned on, your call content can only be heard by
devices that use the same type of scrambling point as you, that is, both
parties need to set the same scrambling point in order to communicate
normally, and prevent other radios with the same frequency from stealing
information. Note: This radio can be programmed to turn on or off the
scrambling function.
Busy channel lock
(Factory setting: Off)
When the channel is occupied, regardless of whether the decoding is successful
or not, pressing the [PTT] key will cause the radio to emit a “beep” warning
tone and stop transmitting. To stop the warning tone, please release the [PTT]
key and return to receive mode.
QT/DQT
Some channels may have preset QT/DQT. It allows you to ignore (not listen to)
calls from radios using different QT/DQT settings on the same channel.When you
receive a signal that is different from your radio QT/DQT settings, you will
not hear this signal but the status indicator will display a green light.The
signal you transmit can only be received by radios with the same QT/DQT
settings. Note: 1. Although using QT/DQT settings can prevent you from
listening to unwanted calls, it does not mean that your call is confidential.
2. This radio supports manual input of non-standard QT/DQT (QT: 30.0Hz-260Hz,
step 0.1Hz; DQT: DOOON – D777N, step 1)
Wide/narrow bandwidth selection
(Factory setting: 16 channels are all 12.5KHz narrowband)
Users can choose to communicate with 25kHz (broadband) or 12.5KHz (narrowband)
channel intervals through programming software according to their usage needs.
Transmission time limit
(Factory setting: 60 seconds)
Set up warning function by software can remind you before the time-out timer
reach.The transmission time limit function is to prevent any calling party
from occupying the channel for too long, and to limit users from transmitting
over time to avoid the risk of damage to the radios due to prolonged
transmission.If the continuous transmission exceeds the programmed time, the
radio will stop transmitting, the transmission indicator light will turn from
red to green, and a warning tone of “beep~–” will sound. To stop the warning
tone, please release the [PTT] key and the radio will return to receiving
mode.
The battery saving function
(Factory setting: On) Reduces battery consumption when no signal is received
or no operation is performed (no buttons, no rotary switch).In standby mode,
the radios will automatically enter sleep mode after 5 seconds when there is
no transmission or button operation.When the radio receives a signal or
operates, it will automatically exit the battery saving function.
Battery low voltage alarm function
The low battery voltage alarm reminds you that the battery needs to be
recharged.When the battery level drops to the predetermined value, the message
“Please Charge” is reported every 5 seconds, and pressing the PTT key will not
activate the transmission. Note: When the battery low voltage alarm prompts
“Please charge”, please replace the battery or charge it in time to avoid
affecting your use.
Tail sound selection
(Factory setting: Regular) When configuring radios from different
manufacturers, you can configure them through the tail sound selection
setting. There are two ways to choose “regular” and “special” for this device
15
Strengthen the decoding function
This radio has a frequency scanning and decoding function, which is designed
for some radios with frequency hopping. When you don’t know the target radios
frequency and want to call with them, use this function, you can communicate
with the target radio.
Specific steps:
1. Select channel 1 or channel 2, turn off radio first, then press and hold
the PTT key + side key 3 to turn radio on. Aafter 3 seconds, it will enter the
mode with the transmission light (red light) flashing 3 times, and “DiDiDi”
three times to prompt and report the current channel, indicating that it has
entered the scanning decoding mode. 2. Under this mode, ask for target radio
to transmit, so your radio will receive the frequency scanning and decoding.
If it is successful for frequency scanning and decoding, the transmission
light will flash once with a prompt tone. Then you can talk to the target
radio and verify whether this function is successful to be used.
(Note: This radio can decode the all other radios with frequency hopping on
market. Entering channel 1 is a regular mode, and entering channel 2 is a
strong mode)
In the frequency scanning and decoding mode, short press the side key 3 to
rescan and decode. If the frequency scanning and decoding are not successful
for a long time (greater than 10 seconds), please short press this key to
rescan again.Long press the side key 3 to exit the frequency scanning and
decoding mode(exiting the frequency scanning and decoding mode will prompt
three “DIDIDI” tones). After successfully scanning and decoding, the radio
will automatically store the code value. You can read the data through the
programmable software and write it to other radio.
