1.6.2 Antenna Care and Replacement
Do not use the portable radio with a damaged or missing antenna. A minor
burn may result if a damaged antenna comes into contact with the skin.
Replace a damaged antenna immediately. Operating a portable radio with the
antenna missing could cause personal injury, damage the radio, and may
violate FCC regulations.
Use only the supplied or approved antenna. Unauthorized antennas, modifications,
or attachments could cause damage to the radio unit and may violate FCC
regulations. (Refer to Table 4-1.)
1.6.3 Electronic Devices
RF energy from portable radios may affect some electronic equipment. Most
modern electronic equipment in cars, hospitals, homes, etc. is shielded from RF
energy. However, in areas in which you are instructed to turn off two-way radio
equipment, always observe the rules. If in doubt, turn it off!
1.6.4 Aircraft
•
Always turn off a portable radio before boarding any aircraft!
•
Use it on the ground only with crew permission.
•
DO NOT use while in-flight!!
1.6.5 Electric Blasting Caps
To prevent accidental detonation of electric blasting caps, DO NOT use two-
way radios within 1000 feet of blasting operations. Always obey the "Turn Off
Two-Way Radios" signs posted where electric blasting caps are being used
(OSHA Standard: 1926.900).
1.6.6 Potentially Explosive Atmospheres
Areas with potentially explosive atmospheres are often, but not always,
clearly marked. These may be fueling areas, such as gas stations, fuel or
chemical transfer or storage facilities, and areas where the air contains
chemicals or particles, such as grain, dust, or metal powders.
Sparks in such areas could cause an explosion or fire resulting in bodily
injury or even death.
Turn off two-way radios when in any area with a potentially explosive
atmosphere. It is rare, but possible that a radio or its accessories could
generate sparks.
