Transmit and Receive Procedure Your two-way radio contains a transmitter and a receiver. To control your exposure and ensure compliance with the general population/uncontrolled environment exposure limits, always adhere to the following procedure:

Transmit no more than 50% of the time. To transmit (talk), press the Push to Talk (PTT) button. To receive calls, release the PTT button. Transmit no more than 50% of the time, or less, is important because the radio generates measurable RF energy exposure only when transmitting (in terms of measuring standards compliance). Exposure to Radio Frequency Energy Your radio is designed to comply with the following national and international standards and guidelines regarding exposure of human being to radio frequency electromagnetic energy:

Two-Way Radio Operation When using your radio as a traditional two-way radio,hold the radio in a vertical position with the microphone one to two inches (2.5 to 5cm) away from the lips. MADE IN CHINA FCC Statement This equipment has been tested and found to comply with the limits for 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 to 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. RF Exposure Warning This equipment must be installed and operated in accordance with provided instructions and must not be co-located or operating in conjunction with any other antenna or transmitter. End-users and installers must be provide with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance. The SAR limit adopted by US is 1.6 W/kg averaged over 1 grams of tissue. The highest SAR value reported under this standard during product certification for use at the ear is 0.117W/kg and when properly worn on the body is 0.270W/kg. REGULATORY Information Important: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this device.
