RF exposure safety warning for operators manual

Physical Mounting:

Select a mounting location where the unit is easily accessed. Mount the unit

in the desired position using the provided Trunnion mount or flush

mounting kit. See Figures 1.2 and 1.3.

Power supply wiring:

CAUTION: Make sure that the provided fuse holder is installed on the

power cord between the radio and the power source, and that the

proper sized fuse (7.5A) is installed.

Use a 12 volt +30%/-10% (10.8 to 15.6VDC) DC power source for proper

operation. Do not exceed 16.0 volts. Direct connection to the battery is

recommended. Connect the heavy red wire, with in-line fuse installed, to

the positive (+) terminal and the heavy black wire to the negative (-)

terminal. Negative ground is required for the USA/Canada version of the

SEA 157S.

CAUTION: If the polarity of the power wires is reversed (Black to

positive, Red to negative), and power is accidentally applied to the radio,

the in-line fuse will blow. It is possible that damage could also occur to

some internal components. Application of voltages greater than 16.0 volts

will produce the same result. (Refer service to a qualified technician.)

Antenna installation and RF Exposure Safety Warning:

To comply with FCC Limits for Human Exposure to Radiofrequency

Electromagnetic Fields for General Population/Uncontrolled Exposure, the

antenna must be mounted in such a manner as to prevent passengers or

personal from coming within 1 meter (39.4 inches) of the radiating portion

of the antenna. (Re: FCC OET Bulletin 65, Section 4, Public Exposure)

Antenna wiring:

Use only the best available 50 ohm coaxial antenna cable and connectors.

The antenna must be vertically polarized. Check the antenna system for less

than 1.5:1 VSWR with an in-line wattmeter before final installation. The

antenna cable PL-259 connector should be tightly fastened to the antenna

connector on the back of the unit. All antenna connections should be

carefully protected from the weather.
