OPERATING NOTES
When transmitting with a portable radio, hold the radio in a vertical position with its
microphone 5 to 10 cm (2 to 4 inches) away from your mouth. Keep the antenna at
least 2.5 cm (1 inch) 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 (1 inch) from your body when transmitting.
PRECAUTIONS
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 (2 to 4 inches) away
from the lips and the transceiver is vertical.
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 Battery listed below
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 –30°C (–22°F) or above +60°C (+140°F).
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.
BE CAREFUL! The series transceivers employ waterproof construction, which
corresponds to IPX7 of the international standard IEC 60529 (2001), 1 m depth for 30
minutes. However, once the transceiver has been dropped, waterproofing cannot be
guaranteed due to the fact that the transceiver may be cracked, or the waterproof seal
damaged, etc.
The use of non-HYT battery packs/chargers may impair transceiver performance and
invalidate the warranty.
FCC CAUTION:
Changes or modifications to this device, not expressly approved by HYT, could void
your authority to operate this transceiver under FCC regulations.
