4. Before Use 
4.1 Instruction 
To ensure optimum performance and reliability of the repeater, please read the following instructions 
carefully.  
Operation Environment 
The repeater must be installed in a dry and well-ventilated place with ambient temperature of -30  ℃ to 
+60℃  and relative humidity of not more than 95%.   
Voltage Check 
Check whether the input voltage is within the operating voltage of the repeater (DC power supply: 13.6V
±15%; AC power supply: 90V to 264V). 
4.2 Wall-mount Bracket Installation (Optional) 
Please contact your dealer to purchase a wall-mount bracket kit to install the repeater on the wall.   
No.  Part Name  No.  Part Name 
1  Expansion Rubber Plug  3  Self-tapping Screw 
2 Wall-mount Bracket  /  / 
4.2.1 Installation Tools 
Tools required for installing the repeater include an electric drill and a T10 torx screwdriver.   
4.2.2 Installation Steps 
Step 1  To install the wall-mount bracket, do as follows:   

 7
1. Use the electric drill to drill three holes on the wall which align with that on the wall-mount 
bracket;  
2. Put the expansion rubber plug into the drill holes; you can ignore this step if the wall is not a 
concrete wall; 
3. Use three ST4X16 self-tapping screws to fasten the bracket on the wall.   
Note: Make sure the wall can support the repeater’s weight before drilling.   

 8
Step 2  To amount the repeater on the bracket, do as follows:   
1. Align the hanging screws on the upper side of the repeater with the notch of the bracket and 
hang the repeater on the bracket;   
2. Move the repeater side to side slightly to ensure the hanging screws reach the bottom of the 
notch.  
4.2.3 Product Check 
Please check whether the repeater works properly by observing the 7 LEDs located in the front panel 
after the repeater is powered on via the AC Power Switch key.

5. Alarm Information 
The repeater will have real-time detection of its status automatically. When the repeater is operating 
abnormally, the alarm indicator on the front panel will remain glowing red until all alarms are eliminated.   
When an alarm event occurs, you can diagnose and handle the problem via the RDAC application 
provided by us or contact your local dealer for technical support.   
Alarm types and causes are listed in the table below:   
Alarm Type  Alarm Cause 
External Power 
Abnormal 
High Voltage: The input voltage is higher than 15.8V±0.2V.  
Low Voltage: The input voltage is lower than 11V±0.2V.  
High Temperature  Temperature sensor detects a temperature above 85℃.  
Abnormal VSWR  VSWR > 3:1.   
Over-high VSWR will damage the PA module or even disable it.   
TX Unlock  TX PLL is unlocked, and the repeater stops transmitting and repeating.   
RX Unlock  RX PLL is unlocked, and the repeater stops receiving and repeating.   
Fan Failure  PA temperature is higher than the fan off temperature configured via CPS.

6. Troubleshooting 
Phenomena  Analysis  Solution 
Power-on Failure.   
The power cord may be 
unconnected or not securely 
connected to the outlet.   
Properly connect the power cord and 
ensure secure connection.   
The power supply may output 
improper voltage.   
Check if the power supply outputs the 
voltage within the required range (DC 
power supply: 13.6V ±15%; AC power 
supply: 90V to 264V). If not, replace the 
power adapter.   
Unable to 
communicate with 
other members.   
TX/RX frequency of the repeater 
is inconsistent with that of 
portable/mobile radios.   
Check if the frequencies are consistent. 
Reset the frequencies when necessary. 
Failed to repeat useful signal due 
to strong interference signals.   
If you cannot remove or bypass the 
interference source, change to operate at 
other frequencies.   
The group member is out of the 
coverage of the repeater.   
Move towards the coverage of the 
repeater.  
If the above solutions cannot fix the problems, or there are other questions, please contact Hytera or the 
dealer for more technical support.

below.  
Product Care 
z  Keep the repeater in good environmental conditions to ensure reliability.   
z  Do not place other equipment on top of the repeater to ensure optimal heat dissipation.   
z  Do not pierce or scrape the product.   
z  Keep the product far away from corrosive environments.   
z  Do not place the product in corrosive agents, solutions or water.   
Product Cleaning 
Caution: Be sure to turn off the repeater before cleaning.
