RF Radiation Information
This product must be restricted to operations in an Occupational/Controlled RF exposure Environments. Users must be fully aware of the hazards of the exposure and able to exercise control over their RF exposure to qualify for the higher exposure limits.
RF Radiation Profile
Radio Frequency (RF) is a frequency of electromagnetic radiation in the range at which radio signals are 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. EU Regulatory Conformance As certified by the qualified laboratory, the product is in compliance with the essential requirements and other relevant provisions of the Directive 1999/5/EC. Please note that the above information is applicable to EU countries only.

Items in the Package

Please unpack carefully and check that all items listed below are received. If any item is missing or damaged, please contact your dealer.

Product Overview

Note: If the repeater is manufactured without internal duplexer, then part 8 will be an external duplexer RX port; if it is manufactured with internal duplexer, then there will be no connection inside part 8.
Rear Panel

Before Use

Instructions
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 wellventilated 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).
Wall-mount Bracket Installation (Optional)
If you need to install the repeater on the wall, please contact your dealer to purchase a wall-mount bracket.

Installation Tools
An electric drill and a T10 torx screwdriver.
Installation Procedures
A. Install the wall-mount bracket.

1. Drill three holes into the wall, with each hole aligned with those of the wall-mount bracket.
2. Put the plastic wall anchor into the drilled holes. Skip 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.

B. Install the repeater on the bracket.

1. Align the screws on the upper side of the repeater with the notches of the bracket and mount the repeater onto the bracket, as shown in the figure below;
2. Move the repeater side to side slightly to ensure the screws fit into the bottom of the notch.

Product Check
Check whether the repeater works properly by observing the seven LED indicators in the front panel after the repeater is powered on via the AC Power Switch.

Status Indication

The LED indicators on the front panel indicate the following repeating status:

● Digital mode: The repeater is transmitting in Slot A.
Slot A RX LED Indicator| Green| ● Analog mode: The repeater is receiving.
● Digital mode: The repeater is receiving in Slot A.
Slot B TX LED Indicator| Red| Digital mode: The repeater is transmitting in Slot B.
Slot B RX LED Indicator| Green| Digital Mode: The repeater is receiving in Slot B.
Alarm LED Indicator| Red| Alarm occurs. The alarm LED indicator will remain red
until all alarms are eliminated.

Alarm Information
The repeater will have real-time detection of its operation status automatically. When it is operating abnormally, the alarm LED indicator on the front panel will glow red until all alarms are eliminated. When an alarm event occurs, you can diagnose and solve the problem via the RDAC application provided by us or contact your local dealer for technical support. Alarm types and causes are as listed below:

than 15.8V±0.2V.
Low Voltage: The input voltage is lower than 10.8V±0.2V.
High Temperature| Temperature sensor detects the temperature above 85℃.
Abnormal VSWR| VSWR > 3:1. Over-high VSWR will damage tPA module or even disable it.
TX Unlock| TX LL is unlocked, and t h repeater stops transmitting an repeating.
RX Unlock| RXPLL is unlocked, and the repeater stops receiving and repeating.

Troubleshooting

Phenomena| Analysis|

Solution

---|---|---
Power-on Failure.| The power cord may be disconnected or not securely connected to the outlet.| Properly connect the power cord and ensure secure connection.
The fuse in the power cord is damaged.| Check whether the DC power fuse is damaged. If it is damaged, replace it with a new one.
DC power supply voltage is not within the operating voltage of the repeater.| Check whether the DC power supply voltage is within the operating voltage of the repeater (13.6V±15%). If not, adjust it to proper range.
The radio is 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.
The repeater 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 radio is out of the coverage of the repeater.| Move into the coverage of the repeater.
There’s RX indication on the radios, but members cannot communicate with each other.| Radio ID does not match that of other members.| Sets the same ID with other members.
The CTCSS/CDCSSs of the radios are not consistent.| Check whether the CTCSS/CDCSSs are consistent. Reset the CTCSS/CDCSSs when necessary.
Short communication distance and poor voice quality| Signal loss due to connecting cable damage.| Check whether the damage is serious. Replace the cable when necessary.
The antenna and cable are in loose connection or disconnected.| Secure the connection. Replace the connector when necessary.
Internal damage of the cable.| Replace the cable.
The duplexer (if installed) may be adjusted improperly.| Contact Hytera or the local dealer to re- adjust the duplexer.

If the above solutions cannot fix the problems, or you have other questions, please contact Hytera or the dealer for more technical support.
