Restoring Factory Default Settings:
If you want to set the transmitter and/or receiver back to the condition it was in when they don’t work smoothly by wrong operating, simply press and hold the CH+ button for about 20 seconds until the status LED begins to flash. Power the device off and wait about 30 seconds, then power it on again and it will be restored back to the default settings.

Safety Precautions and Procedures

• DO NOT place transmitter or receiver around direct sunlight or any heat source such as electric/gas stove or heaters of any kind. Do not place near an open flame.

• DO NOT place anything on top of the receiver or transmitter. Allow the unit to sit in an “open-air” environment with plenty of room around it.
  The unit can overheat when not in an “open-air” environment.

• DO NOT take apart the transmitter or receiver for any reason. THIS WILL VOID THE WARRANTY and could cause electric shock injury. There are no user-replaceable parts inside the unit. Units can only be repaired/replaced by the manufacturer.

• DO NOT spill liquid on the unit. Store in a safe dry place free from moisture. NOT FOLLOWING SAFETY PROCEDURES VOIDS ALL WARRANTIES!

FAQ

1. Question: How to Pair the receiver with the transmitter?
   Answer: No need for additional operation. Just follow our installation instructions. The receiver will pair the transmitter automatically.

2. Question: How to change the channel?
   Answer: You just need to change the channel of the transmitter. The receiver will automatically change the channel to match that of its paired transmitter.

3. Question: Why there are mutual interferences between our products and WIFI?
   Answer: Our system uses the 2.4GHz carrier to transmit the audio information from the transmitter to the receiver. Because the frequency of WIFI is also 2.4GHz, there is the potential possibility of interference between our system and WIFI.

4. Question: How to avoid and reduce interference between our products and WIFI?
   Answer: As the product has 10 channels, if you want to avoid interference between our products and WIFI, we recommend changing the channel to 0 or 1.

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE

| Before using this radio, read this guide which contains important operating instructions for safe usage and RF
energy awareness and control for compliance with applicable standards and regulations.
---|---

This radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. RF energy, which when used improperly, can cause biological damage. All Retekess radios are designed, manufactured, and tested to ensure they meet government- established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of the radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following websites for more information on what RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits: http://www.who.int/en/

Local Government Regulations
When radios are used as a consequence of employment, the Local Government Regulations requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a product label directing users to specific user awareness information. Your Retekess radio has a RF Exposure Product Label. Also, your Retekess user manual or separate safety booklet includes information and operating instructions required to control your RF exposure and to satisfy compliance requirements.

Radio License (if appropriate)
Governments keep the radios in classification, business radios operate on radio frequencies that are regulated by the local radio management departments (FCC, ISED, OFCOM, ANFR, BFTK, Bundesnetzagentur…).To transmit on these frequencies, you are required to have a license issued by them. For the detailed classification and the use of your radios, please contact the local government radio management departments.

RF Exposure Information

• DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also cause you to exceed RF exposure limits. A proper antenna is an antenna supplied with this radio by the manufacturer or an antenna specifically authorized by the manufacturer for use with this radio, and the antenna gain shall not exceed the specified gain by the manufacturer declared.
• DO NOT transmit for more than 50% of total radio use time, more than 50% of the time can cause RF exposure compliance requirements to be exceeded.
• During transmissions, your radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so.
• The device complies with RF specifications when the device is used at 5mm from your body. Third-party belt clips, holsters, and similar accessories used by this device should not contain any metallic components. Body-worn accessories that do not meet these requirements may not comply with RF exposure requirements and should be avoided.
• DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites.

Avoid Choking Hazard
Small Parts. Not for children under 3 years.
Protect your hearing:

• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy surroundings.
• Turn down the volume before adding a headset or earpiece.
• Limit the amount of time you use headsets or earpieces at high volume.
• When using the radio without a headset or earpiece, do not place the radio’s speaker directly against your ear.
• Use care with the earphone may be possible excessive sound pressure from earphones and headphones can cause hearing loss.
  Note: Exposure to loud noises from any source for extended periods of time may temporarily or permanently affect your hearing. The louder the radio’s volume, the less time is required before your hearing could be affected. Hearing damage from loud noise is sometimes undetectable at first and can have a cumulative effect.

Avoid Burns
Antennas

• Do not use any portable radio that has a damaged antenna. If the damaged antenna comes into contact with the skin when the radio is in use, a minor burn can result.
  Batteries (If appropriate)

• When the conductive material such as jewelry, keys, or chains touch exposed terminals of the batteries may complete an electrical circuit (short circuit the battery) and become hot to cause bodily injury such as burns. Exercise care in handling any battery, particularly when placing it inside a pocket, purse, or other containers with metal objects Long transmission

• When the transceiver is used for long transmissions, the radiator and chassis will become hot.
