IMPORTANT INFORMATION
CONCERNING UHF CB RADIO
The use of the Cizen Band radio service
is licensed in Australia by the ACMA Radio
communicaons (Cizens Band Radio
Staons) Class Licence and in New Zealand
by the Ministry of Economic Development
New Zealand (MED). A General User Radio
Licence for Cizens Band radio and operaon
is subject to condions contained in those
licences.
The class licence for users and equipment
operang in the CB/PRS 477 MHz band has
been amended. This radio meets the new 80
channel standard.
In simple terms the same amount of spectrum
is available; however, radio transceivers can
now operate in a narrower bandwidth and
hence use less spectrum. These radios are
generally referred to as narrowband or 12.5
kHz radios. By using 12.5 kHz channel spacing
instead of 25 kHz, the 40 channels originally
allocated can now be expanded to 80 channels
thereby doubling the channel capacity and
relieving congeson in the UHF CB/PRS band.
Original 40 channel wideband Radios will
connue to operate on the original 40 channels,
however they will not be able to converse
on the newer channels 41 – 80. The newer
narrowband radios will be able to converse
with all older 40 channel wideband radios on all
channels 1 to 40 as well as the newer channels
allocated from 41 to 80.
The mixing of narrowband and wideband
radios in the same spectrum can cause some
possible operang issues of interference and
varying levels of received volume.
SAFETY INFORMATION
The TX4610 is a radio transming device.
• When transming, keep the antenna more
than 25 mm from any part of the head
or body.
• Do not transmit near electrical blasng
equipment or in explosive atmospheres.
• Do not allow children to operate a radio
transmier unsupervised.
POSSIBLE ISSUES
When a new narrowband radio receives a
transmission from an older wideband radio the
speech may sound loud and distorted - simply
adjust the radio volume for best performance.
When an older wideband radio receives a signal
from a new narrowband radio, it may sound
quiet - simply adjust your volume for best
performance.
There can be interference from a transming
radio if it is close to another transming radio
using a channel adjacent to the channel you are
listening to. Simply try going up or down a few
channels from the currently selected channel.
The above situaons are not a fault of the radio
but a symptom of operang wideband and
narrowband radios in the same bandwidth. This
possible interference will decrease over me
as the populaon of wideband radios ages and
decreases.
Further informaon and updates are available
from the Australian Communicaons and Media
Authority (ACMA) at www.acma.gov.au and
the Ministry of Economic Development (MED),
Radio Spectrum Management at: www.rsm.

EMERGENCY CHANNELS
The ACMA has allocated channels 5/35 for
emergency use only. Channel 5 is the primary
Simplex Emergency Channel. Where a Channel
5 repeater is available, you should select Duplex
on CH 5.
NOTE: Channel 35 is the input channel
for the Channel 5 repeater therefore
Channel 35 should also not be used
for anything other than emergency
transmissions.
TELEMETRY CHANNELS
ACMA regulaons have allocated channels
22 and 23 for telemetry only applicaons and
have prohibited the transmission of speech on
these channels. Consequently the TX4610 has a
transmit inhibit applied to channels 22 and 23.
In the event addional telemetry/telecomand
channels are approved by the ACMA, these
channels shall be added to those currently
listed where voice transmission is inhibited.
Currently transmissions on channels 61, 62 and
63 are also inhibited and these channels are
reserved for future allocaon.
