FCC Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
· Reorient or relocate the receiving antenna. · Increase the separation between the equipment and receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected. · Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modific ations to this device not explicitly approved by manufacturer could void your authority to operate this equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Specific Absorption Rate (SAR) information: This Walkie Talkie meets the government’s requirements for exposure to radio waves. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health. FCC RF Exposure Information and Statement the SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue.
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 the 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 requirem-ents 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. ·DO NOT operate the transmitter in areas that are sensitive to elect- romagnetic radiation such as hospitals, aircraft, and blasting sites. ·Portable Device, this transmitter may operate with the antenna(s) documented in this filing in Push-toTalk and body-worn configurations. RF exposure compliance is limited to the specific belt-clip and accessory configurations as documented in this filing and the separation distance between user and the device or its antenna shall be at least 2.5 cm. · General population/uncontrolled Radio, this radio is designed for and classified as “General population/uncontrolled Use”.

Operating Instructions: · Transmit no more than the rated duty factor of 50% of the time. To Transmit (Talk),push the Push to Talk (PTT) button. To receive calls(listen), release the PTT button. Transmitting 50% of the time, or less,is important because the radio generates measurable RFenergy exposure only when transmitting in terms of measuring for standards compliance. · When operating in front of the face, worn on the body, always place the radio in a Retevis approved clip, holder, holster, case, or body harness for this product. Using approved bodyworn accessories is important because the use of Non-Retevis approved accessories may result in exposure levels, which exceed the IEEE/ICNIRP RFexposure limits.
