OPERATIONAL NOTES
vii. UHF CB repeaters extend the operational range of
your radio. Repeaters operate utilising two channels
(repeater input/repeater output). It is important to avoid
operation on locally used repeater input channels (in the
channel range of 31 to 38 and 71 to 78) or locally used
repeater output channels (in the channel range of 1 to 8
and 41 to 48), unless long distance communication via
the repeater is specifically required. See the section on
repeater operation for more information.
viii. Please be aware that the UHF CB network may
experience possible operational issues during the
changeover to narrowband. This transceiver operates
on 12.5 kHz channel spacing. During the changeover
period from 25 kHz to 12.5 kHz spacing, there may be
some loss of quality when 12.5 kHz (narrowband, 2.5
kHz deviation) transmissions are received on 25 kHz
(wide band, 5.0 kHz deviation) equipment, and vice-
versa. There may also be interference due to older
equipment being operated on channels adjacent to new
narrowband channels, as the channel setting on these
may cause some 'overlap'. A list of currently authorised
channels can be found on the ACMA website (Australia)
and on the MED website in New Zealand.

PRECAUTIONS

R WARNING! NEVER
outlet. This may pose a fire hazard or result in an electric shock.
CAUTION: NEVER
operate or touch the radio and
microphone with wet hands. This may result in an electric
shock or damage the radio and microphone.
CAUTION: NEVER
connect the radio to a power
source of more than 27.6 V DC. This will damage the radio.
CAUTION: NEVER
connect the radio to a power
source using reverse polarity. This will damage the radio.
CAUTION: NEVER
cut the DC power cable between
the DC plug and fuse holder. If an incorrect connection is
made after cutting, the radio may be damaged.
CAUTION: NEVER
expose the radio and microphone
to rain, snow or any liquids. The radio and microphone may
be damaged.
CAUTION: NEVER
place the radio where normal
operation of the vehicle may be hindered or where it could
cause bodily injury.
DO NOT
push the PTT when not actually intending to transmit.
DO NOT
allow children to play with any radio equipment
containing a transmitter.
connect the radio to an AC
