The radio must be serviced and installed only by a qualified technician. Be sure that the radio is properly
grounded according to the installation instructions.
CAUTION
Before jump starting or changing the vehicle battery, it is strongly suggested that DC
power connector(s) be disconnected from the radio equipment (including control
head(s), if any). This will prevent voltage surges that may occur from damaging the
radio equipment.
This equipment generates or uses radio frequency energy. Changes or modifications to this equipment
may cause harmful interference unless the modifications are expressly approved in the instruction manual.
The user could lose the authority to operate this equipment if an unauthorized change or modification is
made.
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.
Government law prohibits the operation of unlicensed transmitters within the territories under government
control. Illegal operation is punishable by a fine, imprisonment, or both. Refer service to qualified
technicians only. Do not operate the transceiver in explosive atmospheres (gases, dust, fumes, etc.).
2.1 OCCUPATIONAL SAFETY GUIDELINES AND SAFETY TRAINING
INFORMATION
The M-803 mobile radio transmits using a remote antenna. When it is ON, it receives and transmits radio
frequency (RF) signals. In 1996, the Federal Communications Commission (FCC) adopted RF exposure
guidelines with safety limits, based on the recommended limits of the National Council on Radiation
Protection and Measurements (NCRP) and the American National Safety Institute (ANSI).
The design of the M-803 mobile radio complies with the FCC guidelines for Occupational/Controlled
exposure to RF electromagnetic fields, as measured by the Maximum Permissible Exposure (MPE). To
assure optimal performance and human exposure to RF electromagnetic energy is within the FCC
guidelines, always adhere to the following:
1. The push-to-talk button should only be pressed when intending to send a voice message.
2. The radio should only be used for necessary work related communications.
3. The radio should only be used by authorized and trained personnel and should not be operated by
children.
1 The MPE radius is the minimum distance from the antenna axis (distances listed in ) that persons should maintain
in order to avoid RF exposure higher than the allowable MPE level set by the FCC.
