2. Place the repeater horizontally with its back (the side with the product information label) upwards.
3. Put the multi-functional bracket horizontally on the back of the repeater as shown in the figure below, and align the screw holes on the bracket to those of the repeater.
4. Secure the bracket with six M3*6 screws.
5. Step 2 Assemble the power supply management system.
6. Push the power supply management system along the slots of the bracket slowly to the bottom of the bracket, with the front of the system upwards. See the following figure.
7. Fasten the screws on the bracket to secure the system.
8. Step 3 Connect the system to the repeater with the power cord as shown in the following figure.
9. Plug the aviation plug (female) of the power cord into the power input of the repeater and fasten the screws on the plug.
10. Plug the aviation plug (male) of the power cord into the power output of the system and fasten the screws on the plug.

Product Check
After powering on the repeater, check whether works properly by observing the seven LEDs and the LED segment display located in the front panel.

Basic Operations

Powering On/Off

• Powering on/off manually
  • To power on, long press the Power On/Off key for about 2s after connecting the power supply with the power adapter.
  • To power off, long press the Power On/Off key.
• Auto Power On
  If the power of the adapter happens to be cut off or the power adapter runs out of the battery power when in use, the repeater will be powered off forcibly. After that, when the power adapter restarts to supply power, the repeater will power on automatically

Adjusting the Power Level
You can request your dealer to set the Tx power to High or Low. High power can extend the repeater coverage, enabling you to communicate with farther radios.

Changing the Channel
You can switch the channels by pressing the Channel Up/Down keys on the front panel. The Channel Up key is for the former channel and the Channel Down key for the latter one. The alias of the current channel is displayed on the LED segment display.

PTT Transmitting
If you have purchased the remote speaker microphone, you can press the PTT key on it to communicate with other radios. Then the LED on the front panel will indicate the repeater status. Please refer to “LED”. When the repeater is in a digital or mixed channel (“PTT Tx Channel Type” will be “Digital” then), if “Tx Contact Name” is not defined, the Digital Mode indicator (blue) will flash once rapidly when you hold the PTT key.

Note: “PTT Tx Channel Type” and “Tx Contact Name” are set via the programming software by the dealer.

Alarm Information

The repeater will have real-time detection of its status automatically. If the relative alarms are enabled, when the repeater is working improperly, the LED segment display will show the corresponding sign and the alarm indicator on the front panel will glow red.

Battery Mismatch
When powered by a battery box, the repeater will examine whether the battery in the box matches its requirements in a real-time way. When the battery does not match the requirement, the alarm indicator will glow red and the LED segment display will show “E1”. When this alarm is given, the repeater cannot work properly and will power off automatically in 3s. Then please ask your local dealer to replace the power supply management system or for further help. If you switch to an external power supply, this alarm will be eliminated with the segment disappearing and the alarm indicator going out.

Low Battery
When powered by battery, the repeater will have realtime detection of the battery power of the power supply management system. When the battery power falls below the low-battery alarm threshold (12% of the battery capacity by default), the alarm indicator will glow red and the LED segment display will show “E2”.

When this alarm segment is displayed, the repeater will still work properly and will power off automatically when running out of power.
In this case, you need to take the following measures:

1. Check the power indicator on the power supply management system to see if the power is low. If the power is low, please charge the power supply management system or replace it.
   Caution: When an external power supply is connected, the repeater will power on automatically.

2. If you cannot solve the problem, contact your local dealer for technical support.

When the battery power is higher than the low-battery alarm threshold, the alarm will be eliminated with the segment disappearing and the alarm indicator going out.

External Power Abnormal
When powered by a power adapter, the repeater will have real-time detection of the output voltage of the power adapter. When the output voltage falls off the range of the operating voltage, the alarm indicator will glow red and the LED segment display will show “E3”.

When this alarm is given, the repeater cannot work properly and will power off automatically in 3s. If the automatic powering off is caused by the external power
supply error, the repeater will not power on automatically after it returns to normal operation. You will need to turn it on. If the power supply returns to normal operation within the 3s, the alarm will be eliminated so that the repeater will not power off.
In this case, you need to take the following measures:

1. Check whether the power adapter is damaged. If it is damaged, please replace it.
2. Check through the voltmeter whether the voltageinputted by the external power supply is over low or over high. If it is over low or over high, please replace it or use the battery for power supply.
3. If you cannot solve the problem, contact your local dealer for technical support.

TX/RX Unlock
Normally, after being powered on, the repeater has its Tx and Rx work properly in locked status. Once the repeater detects that the Tx/Rx PLL is unlocked, its alarm indicator will glow red and there will be a sign (“E4” for Tx Unlock, “E5” for Rx Unlock) on the LED segment display.

When such alarm is given, the repeater will terminate part of its features automatically. Now you will need to contact your local dealer for technical support. When Tx/Rx returns to the locked status, the alarm will be eliminated with the segment disappearing and the alarm indicator going out.

Over Temperature
When the operating temperature of the PA module is higher than 85℃, the alarm indicator will glow red and the LED segment display will show “E6”.

When this alarm is given, the repeater can still work properly. During a rise in ambient temperature, the repeater will keep track of the Tx power with adjustments in order to lower the temperature.
And you need to take the following measures:

1. Check whether the ambient temperature and ventilation conditions of the repeater satisfy the foregoing installation requirements. If not, please make improvements as soon as possible.
2. 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.
3. If the above measures fail to solve the problem, contact your local dealer for technical support.

VSWR Alarm
When transmitting, the repeater will detect the voltage standing wave ratio (VSWR) of the Tx antenna of the PA module. Over-high VSWR will damage the PA module or even disable it. When the VSWR exceeds the normal range, the alarm indicator will glow red and the LED segment display will show “E7”:

When this alarm is given, the repeater can still work properly.
And you need to take the following measures:

1. Check if the Tx frequency is within the frequencyrange of the antenna, as improper antenna will result in poor transmitting performance or even damage to the transmitter. If not, please contact your local dealer to replace the antenna.
2. Check if the connection between the transmitter and RF adapter cable or antenna/feed line is loose or damaged. If yes, please replace the cable.
3. If you cannot solve the problem, contact your local dealer for technical support.

When the VSWR returns to the operation range, the alarm will be eliminated with the segment disappearing and the alarm indicator going out.
