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 body worn accessories is important
because the use of non-UNICATION approvedaccessories 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.
• This radio transmitter (IC:3819A-U3700800) has been approved by Industry
Canada to operate with the antenna types listed below with the maximum
permissible gain and required antenna impedance for each antenna type
indicated. Antenna types not included in this list, having a gain greater than the
maximum gain indicated for that type, are strictly prohibited for use with this
device.
