Section # 3 WARNINGS!

∇ Directly wired vehicle antennas, mounted a minimum distance of 20 cm (7.87 inches) away from the body of any

user or nearby persons is recommended.

∇ Mounting an 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 manufacturer’s

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’s 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 3 dB 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.
