Safety and General Information
Important Information on Safe and Efficient Operation Read. This Information Before Using Your Radio The information provided in this document supersedes the general safety information contained in user guides published prior to July 2000.
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 beings to radiofrequency
electromagnetic energy: Two-Way Radio Operation
When using your radio as 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.
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 user’s 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 provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance. The SAR limit adopted by the US is 1.6 W/kg averaged over 1 gram 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. Your radio is set up to transmit a regulated signal at an assigned frequency. It is against the law to alter or adjust the settings inside the radio to exceed those limitations. Any adjustments to your radio must be made by qualified technicians.
To be safe and sure: Never open your radio’s case. Never change or replace anything in your radio except the battery. Any attempt to change frequencies or output power of the radio invalidates the approval Your radio might cause TV or radio interference even when it is operating properly. To determine whether Your radio is causing the interference, turn it off. If the interference goes away, your radio is causing it. Try to eliminate the interference by moving your radio away from the receiver. If you cannot eliminate the interference, the FCC requires that you stop using the radio.
Hazardous Environments: Do not operate the radio in hazardous
environments. Explosion or fire may result. Do not operate the radio near
unshielded electrical blasting caps. Under certain conditions, radios can
interfere with blasting operations and may cause an explosion. Turn your radio
OFF to prevent accidental transmission when in a blasting area or in areas
posted: “Turn off two-way radio.”Construction crews often use remote-control
RF devices to set off explosives.
Note: The use of this radio outside the country where it was intended to
be distributed is subject to government regulations and may be prohibited.
WARNING: Read this information before using the radio. In August 1996 the
Federal Communications Commission (FCC) of the United States with its action
in Report and Order FCC 96-326 adopted an updated safety standard for humans.
Exposure to radiofrequency electromagnetic energy emitted by FCC regulated
transmitters. Those guidelines are consistent with the safety standard
previously set by both U.S. and international standards bodies. The design of
the radio complies with the FCC guidelines and these international standards.
Never allow children to operate the radio without adult supervision and the
knowledge of the following guidelines.
WARNING: It is up to the user to properly operate this radio transmitter
to ensure safe operation. Please adhere to the following: Use only the
supplied or an approved antenna. Unauthorized antennas, modifications, or
attachments could impair call quality, damage the radio, or result in
violation of FCC regulations. Do not use the radio with a damaged antenna. If
a damaged antenna comes into contact with the skin, a minor burn may result.
Please contact your local dealer for a replacement antenna.
Any attempt to change frequencies or output power of the radio invalidates the
approval For hand-held operation, the radio should be held at least 25mm from
the user’s face and 0mm from the body. The use of belt clips, holsters, and
similar accessories should not contain metallic components in its assembly.
The use of accessories that do not satisfy these requirements may not comply
with RF exposure requirements and should be avoided. Use only the supplied or
an approved antenna.
