Section # 3 WARNINGS!
∇
Directly wired vehicle antennas must be mounted a minimum distance of 20 cm (7.87”) away from the body of any
user or nearby persons and the antenna.
∇
Mounting a signal amplifier in the engine cavity or on the underside of the vehicle will void the manufacturer’s warranty.
∇
Subjecting the amplifier to voltages greater than 30 Volts DC will damage the amplifier and void the manufacturers
warranty.
∇
Any vehicle with an electrical system of greater than 30 Volts DC should use a step-down voltage regulator to bring the
voltage within the DC operating power range of the amplifier (10 to 30V dc).
∇
Under no circumstances should the amplifier be powered up without a properly connected 50 ohm 800/1900 MHz dual band
cellular/PCS antenna or the amplifier may be damaged, resulting in the manufacturer’ warranty being void.
∇
For optimum performance and compatibility with cellular service provider requirements, it is recommended that an external
antenna with a maximum gain of 3dB be installed.
∇
Use of cellular amplifiers with antennas of higher gains than 7dBi gain is in violation of FCC regulations for which the
offender will be fully liable, and warranty claims will be voided.
It is recommended that only certified automotive installation technicians install this product in a vehicle. Installation by any other
person is at the risk of the vehicle owner and operator.
Section # 4 Installation Selecting a Suitable Location To Mount The Signal Amplifier
Locate a suitable place to mount and conceal the signal amplifier. Suggested mounting locations include: under the dashboard,
under the seat, or in the trunk. For peak performance the signal amplifier should be mounted as close to the phone handset as
possible. The amplifier’s location should be easily accessible and mounted away from moving parts, as well as excessive heat
and moisture.
