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,
release the PTT button. Transmitting 50% of the time, or less, is important because this radio generates measurable RF energy
exposure only when transmitting (in terms of measuring for standards compliance).
• Hold the radio in a vertical position in front of the face with the microphone (and other parts of the radio including the antenna) at least
one inch (2.5 centimeters) away from the nose or lips. Antenna should be kept away from the eye. Keeping the radio at a proper
distance is important since RF exposures decrease with increasing distance from the antenna.
• When worn on the body, always place the radio in the Unication-approved belt clip for this product. Using approved bodyworn
accessories is important because the use of non-Unication-approved accessories may cause exposure levels, which exceed the FCC
occupational/controlled environment RF exposure limits.
• If you are not using a body-worn accessory and are not using the radio in the intended-use position in front of the face (one inch away),
ensure the antenna and the radio are kept at least 0.75 inches (1.9 centimeters) from the body when transmitting. Keeping the radio at a
proper distance is important because RF exposures decrease with increasing distance from the antenna.
Approved Accessories
• Use only Unication-approved supplied or replacement antennas, batteries, and accessories. Use of Non-Unication approved antennas,
batteries, and accessories may exceed the FCC (IEEE) and ICNIRP RF exposure guidelines.
• Here is a list of Unication-approved accessories: Belt Clip, External Speaker/Mic with wired earpiece, clone cable, USB cable, the
2400mAHr Lithium Polymer battery, and the cradle charger.
Electromagnetic Interference/Compatibility
NOTE: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed,
or otherwise configured for electromagnetic compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted notices instruct
you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.
Aircraft
When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in accordance with applicable
regulations per airline crew instructions.
