DEFINITION |
RWARNING
Personal injury, fire hazard or electric shock may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No risk of personal injury, fire or electric shock.
OPERATING NOTES
•When transmitting with a portable radio, hold the radio in a vertical position with its microphone 5 to 10 centimeters away from your mouth. Keep the antenna at least 2.5 centimeters from your head and body.
•If you wear a portable two-way radio on your body, ensure that the antenna is at least 2.5 centimeters from your body when transmitting.
i
PRECAUTION
R WARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm away from the lips and the transceiver is vertical.
R WARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels.
CAUTION! NEVER short the terminals of the battery pack.
NEVER connect the transceiver to a power source other than the BP-226 or BP-227. Such a connection will ruin the transceiver.
DO NOT push the PTT when not actually desiring to transmit.
AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below –25°C or above +55°C.
The basic operations, transmission and reception of the transceiver, are guaranteed within the specified operating temperature range (depending on version). However, the LCD display may be operate correctly, or show an indication in the case of long hours of operation, or after being placed in extremely cold areas.
DO NOT modify the transceiver for any reason.
MAKE SURE the flexible antenna and battery pack are securely attached to the transceiver, and that the antenna and battery pack are dry before attachment. Exposing the inside of the transceiver to water will result in serious damage to the transceiver.
The use of non-Icom battery packs/chargers may impair transceiver performance and invalidate the warranty.
