Term Explanation
Duplexer
Duplexer is a device that allows bi-directional communication. Its
role is to isolate the TX signal from the RX signal to ensure that the
transmitter and receiver can work normally.
Feed Line
Feed Line is the cable or transmission line that connects the
antenna with the radio transmitter or receiver.
Voltage Standing Wave Ratio (VSWR)
VSWR is a value that measures how well a load is impedance-
matched to a source.
Squelch
Squelch is a circuit function that acts to suppress the audio output
of a receiver in the absence of a sufficiently strong desired input
signal.

RF Radiation Information
RF Radiation Profile
Radio Frequency (RF) is a frequency of electromagnetic radiation
in the range at which radio signals are transmitted. RF technology
is widely used in communication, medicine, food processing and
other fields. It may generate radiation during use.
RF Radiation Safety
In order to ensure user health, experts from relevant industries
including science, engineering, medicine and health work with
international organizations to develop standards for safe exposure
to RF radiation. These standards consist of:
●United States Federal Communications Commission, Code of
Federal Regulations; 47CFR part 2 sub-part J;
●American National Standards Institute (ANSI)/Institute of
Electrical and Electronic Engineers (IEEE) C95. 1-1992;
●Institute of Electrical and Electronic Engineers (IEEE) C95. 1 –
1999;
●International Commission on Non-Ionizing Radiation Protection
(ICNIRP) 1998;
FCC Regulations
Federal Communication Commission (FCC) requires that all
radio communication products should meet the requirements set
forth in the above standards before they can be marketed in the
U.S, and the manufacturer shall post a RF label on the product
to inform users of operational instructions, so as to enhance their
occupational health against exposure to RF energy.
Operational Instructions and Training
Guidelines
To ensure optimal performance and compliance with the
occupational/controlled environment RF energy exposure limits in
the above standards and guidelines, users should always adhere
to the followings:
1) Gain of antenna must not exceed 6.5dBi.
2) Antenna Installation: install the mobile antenna at least
3.5 meters away from your body, in accordance with the

Alarm Information
The repeater can automatically detect its operation status in real
time. If the appropriate alarm indication option is checked in the
CPS by your dealer, the LCD will give you a prompt message, and
the Alarm Indicator will glow red in the case of a corresponding
abnormality.
Over Temperature Alarm
When the temperature of PA module exceeds the normal range,
the Alarm Indicator will glow red and the LCD will display the
prompt message below:
Then the repeater will stop transmitting, and you need to:
1. Check whether the temperature of heat sink surface is over
80℃. If yes, proceed with Step 2 and 3 to find out the cause.
Caution:Caution: DO NOT touch the heat sink surface to
avoid burn. You can use a digital thermometer
with thermocouple to measure the temperature
value.
2. Check whether ambient temperature and ventilation conditions
satisfy the foregoing installation requirements. If not, please
make improvements as soon as possible.
3. Check if connection between the transmitter and RF cable
or antenna feed line is loose or damaged. Poor connection
between them could cause high TX power, which would make
the temperature of the heat sink rise quickly. If yes, secure or
replace the cable or antenna feed line.
4. If the above measures fail to solve the problem, contact your
local dealer for technical support.
When temperature falls into normal range, the prompt message
will disappear, and theAlarm Indicator will go out.
Fan Failure Alarm
When the fan fails to work, the Alarm Indicator will glow red and
the LCD will display the prompt message below:
Then the repeater will automatically work at low TX power, to
protect the transmitter from overheating. You need to:
1. Check whether the fan is blocked by an object. If yes, remove
it.
2. If you cannot solve the problem, contact your local dealer for
technical support.
When the fan recovers normal operation, the prompt message will
disappear, and theAlarm Indicator will go out.

Alarm Information
VSWR Alarm
High VSWR (voltage standing wave ratio) of TX antenna
connector could result in damage to the PA, and even failure of
the transmitter. When the VSWR exceeds the normal range, the
Alarm Indicator will glow red and the LCD will display the prompt
message below:
Then the repeater will automatically works at low TX power. You
need to:
1. Check if the operating frequency of repeater is in line with that
of antenna. Both frequency mismatch and improper antenna
could result in poor transmitting performance and even
damage to the transmitter. If yes, please contact your local
dealer to replace the antenna or reprogram your product.
2. Check if the connection between the transmitter and RF cable
or antenna feed line is loose or damaged. If yes, secure or
replace the cable or antenna feed line.
3. If you cannot solve the problem, contact your local dealer for
technical support.
When the VSWR falls within the normal range, the prompt
message will disappear, and theAlarm Indicator will go out.
Low Forward Power Alarm
When the forward power is below the preset value, the Alarm
Indicator will glow red and the LCD will display the prompt
message below:
Then the repeater may continue transmission or terminate it,
subject to the detection result. You need to:
1. Check if the connection between the transmitter and RF cable
or antenna feed line is loose or damaged. If yes, secure or
replace the cable or antenna feed line.
2. If you cannot solve the problem, contact your local dealer for
technical support.
When the forward power is recovered to its normal value, the
prompt message will disappear, and theAlarm Indicator will go out.
Over/Low Voltage Alarm
When power voltage is detected to be over or below the normal
range (11V-15.6V) of repeater, the Alarm Indicator will glow red
and the LCD will display the prompt message below:
High VSWR!
Low Forward
Power

1212
Low Voltage Alarm Over Voltage Alarm
Then the repeater will automatically stop working. You need to:
1. Check whether the power voltage is too low or too high. If yes,
replace the DC power supply or external battery.
2. Check whether the power cord is loose or damaged. If yes,
secure or replace the cord.
3. If you cannot solve the problem, contact your local dealer for
technical support.
When the voltage falls within the normal range, the prompt
message will disappear, and theAlarm Indicator will go out.
Caution:Caution: If low voltage is detected when the
repeater is powered by an external battery, please
charge it in time. Disconnect the battery from the
repeater before charging.
TX/RX Unlock Alarm
When the TX PLL or RX PLL is unlocked, the Alarm Indicator will
glow red and the LCD will display the prompt message below:
Alarm Information
TX Unlock Alarm RX Unlock Alarm
Then the repeater will automatically stop partial operations. You
need to:
1. Disconnect the power supply, open the chassis and check
whether the cabling is right or damaged. If yes, please secure
or replace the cable.
2. If you cannot solve the problem, contact your local dealer for
technical support.
When the PLL recovers normal operation, the prompt message will
disappear, and theAlarm Indicator will go out.
Caution:Caution: disconnect the power supply before
opening the chassis!
