Operation Guide

1. Pairing way of frequency: Press the channel button, to adjust the same channel of the transmitter and the receiver (If the mode is auto-pairing, need not this operation), when the transmitter and receiver been adjusted the same channel, LED off on receiver. After the pairing finish, the system enters into a normal situation.
   Notice: Press Channel button and loose (In three seconds)then channel change once, Totally can change 20 channel; after the channel of the transmitter that been adjusted, if the mode of receiver that is manual pair then need to adjust simultaneously, If pairing is Auto the mode that receiver needn’t any operation, pairing can finish automatically.

2. Channel adjustment: When you meet interference, you should change the channel on the adjusted channel.

3. Adjusting default setting: Press the channel button (CH+) of the transmitter continuously for about 20 seconds, Until Status indicates LED flickers faster, Lose the channel
   button (CH+), restart the machine that Recovery default setting finish.

4. Pairing way of code: Press the channel keys of both the transmitter and the receiver simultaneously for more than 3s (Meanwhile LED remains off for 3s), till LED is on.
   Stop pressing, and it gets into the state of 5s peer-to-peer pairing (Meanwhile LED flickers). After the receiver receives ID paired signals, the LED flickers 3 times, indicating that it gets into the state of receiving, waiting for the signals from the transmitter.
   Normally, led goes out when pairing work is successfully done. If the key shouldn’t be released during Led blinking, which indicates that the transmitter has got into the mode of point-to-mass pairing. and point to mass pairing work of one transmitter to multi receiver that is over. (Note: This feature is used with caution)

5. Special Note: Please check the transmitter’s double-digit display LED which locate belong bottom right corner of the display window when using the microphone, that should show a small dot (Microphone switch), if it does not display a small dot, it should be the audio switch, which can press the volume keys of plus or minus to convert it.

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 an 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 a 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 another container with metal objects
  Long transmission

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