PRECAUTIONS
Please observe the following precautions to prevent
fire, personal injury, and/or transceiver damage:
• Do not attempt to configure your transceiver while
driving; it is simply too dangerous.
• Be aware of local laws pertaining to the use of
headphones/headsets while driving on public roads.
If in doubt, do not wear headphones while mobiling.
• Do not transmit with high output power for extended
periods; the transceiver may overheat.
• Do not modify the transceiver unless instructed by
this manual or other Kenwood documentation.
• Do not expose the transceiver to long periods
of direct sunlight nor place it close to heating
appliances.
• Do not place the transceiver in excessively dusty,
humid or wet areas, nor on unstable surfaces.
• If an abnormal odor or smoke is detected
coming from the transceiver, turn OFF the power
immediately. Contact a Kenwood service station or
your dealer.
• This transceiver is designed for a 13.8 V power
source. Never use a 24 V battery to power the
transceiver.
NOTICES TO THE USER
When condensation occurs inside the transceiver:
Condensation may occur inside the transceiver when the room is warmed
using a heater on a cold day or when the transceiver is quickly moved
from a cold location to a warm location. When condensation occurs, the
microcomputer and/or the transmit/receive circuits may become unstable,
resulting in transceiver malfunction. If this happens, turn OFF the transceiver
and wait for a while. When the condensed droplets disappear, the transceiver
will function normally.
