SAFETY INFORMATION

The CB-320 is a radio transmitting device.

yWhen transmitting, keep the antenna more than 25 mm from any part of the head

or body.

yDo not transmit near electrical blasting equipment or in explosive atmospheres.

yDo not allow children to operate a radio transmitter unsupervised.

IMPORTANT INFORMATION CONCERNING UHF CB RADIO

The use of the Citizen Band radio service is licensed in Australia by the ACMA Radio
communications (Citizens Band radio Stations) Class Licence and in New Zealand by
the Ministry of Economic Development New Zealand (MED). A General User Radio
Licence for Citizens Band radio and operation is subject to conditions contained in
those licences.

The class licence for users and equipment operating 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 con­gestion in the UHF CB/PRS band.

Original 40 channel wideband radios will continue 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 – 40 as well as the newer channels allocated
from 41 – 80.

The mixing of narrowband and wideband radios in the same spectrum can cause
some possible operating issues of interference and varying levels of received volume.

POSSIBLE ISSUES

When a new narrowband radio receives a transmission from an older wideband radio
the speech may sound loud and distorted – simply adjust your radio volume for best
performance.

INSTRUCTION MANUAL

CB-320

PAGE

3

When an older wideband radio receives a signal from a new narrowband radio, the
speech may sound quiet – simply adjust your radio volume for best performance.

Depending on how close your receiving radio is to another transmitting radio, there
can be interference from the transmitting radio if it is 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 situations are not a fault of the radio but a symptom of operating wide­band and narrowband radios in the same bandwidth. This possible interference will
decrease over time as the population of wideband radios ages and decreases.

Further information and updates are available from the Australian Communications
and Media Authority (ACMA) at
Development (MED), Radio Spectrum Management at:

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 channel 5.

Channel 35 is the input channel for the channel 5 repeater therefore channel

NOTE:

35 should also not be used for anything other than emergency transmissions.

TELEMETRY CHANNELS

ACMA regulations have allocated channels 22 and 23 for telemetry-only applications
and have prohibited the transmission of speech on these channels. Consequently the
radio has a transmit-inhibit applied to channels 22 and 23.

In the event that additional telemetry/telecommand 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 allocation.

CHARGING THE BATTERY

The CB-320 is powered by a 3.7V Li-ion battery pack. The battery pack should be fully

charged before being used for the rst time or if you have not used the radio for some

time. This will ensure maximum capacity is available.

TO REMOVE THE BATTERY PACK

1. Ensure that your radio is switched off.

2. Hold the radio horizontally upside-down.

3. Using your ngernail, open the battery lock towards the rear of the radio to release
the battery, then pull the battery up. The battery pack should separate from the radio.
