disappear.
Always listen to ensure the channel is free before transmitting.
TIME-OUT TIMER
The radio has a built-in time-out timer that automatically limits transmissions to
a maximum of 3 minutes of continuous operation. This feature is required by the
ACMA to prevent accidental blocking of the frequency should your PTT become
jammed or be otherwise pressed accidentally.
When the time-out timer activates, the radio will give a low tone for a few
seconds and the transmitter will be temporarily disabled. Release the PTT to
restore normal operation.
BUSY LOCKOUT
When enabled, the Busy Lockout function detects when someone is transmitting
on the channel and prevents your radio from transmitting over them. If you
press the PTT when the channel is busy the radio will emit a warning beep and
the icon won’t be displayed. If this happens, look for the icon on the
display as an indicator that the channel is already in use. If the channel is busy,
simply wait until the channel is clear and press the PTT again.

DYNAMIC VOLUME CONTROL (DVC)
The modulation level of signals heard on the UHF CB band has always varied
considerably resulting in noticeable dierences in received audio volume between
stations.
Generally, users have compensated for this by adjusting the Volume control for
each incoming signal.
With the introduction of 80 channel narrow band transmissions that use lower
levels of modulation, the dierences in received audio volume is likely to increase
further.
Your XRS Connect radio is able to automatically compensate for these variations
by utilising a Dynamic Volume Control. When activated through the menu, this
feature automatically compensates for variations in received audio level resulting
in a constant audio output level to the speaker.
To activate/deactivate Dynamic Volume Control:
1. Press the MENU key.
2. Navigate through the menu to select RADIO SETTINGS > DYNAMIC
VOL.
You can use the MENU key to turn this function on or o.
SELECTING THE ACTIVE SPEAKER
The XRS-330C radio has two speakers - one mounted inside the radio and the
other mounted inside the microphone.
By default, sound is reproduced by both speakers; however if you prefer, one of
these speakers can be switched o, leaving either the radio’s internal speaker or
the microphone’s speaker to reproduce sound.
To select speakers:
1. Press the MENU key.
2. Navigate through the menu to select RADIO SETTINGS > SPEAKER.
You can use the or key to select an option.

XRS-330C 17
MICROPHONE GAIN
The microphone gain controls the sensitivity of the microphone to your voice
input level. If you are quietly spoken or are operating in a quiet environment you
can increase the microphone gain to make your voice sound clearer. If your voice
is quite loud or you are working in a noisy environment and wish to minimise the
amount of background noise that is picked up, you should reduce the microphone
gain.
To adjust microphone gain:
1. Press the MENU key.
2. Navigate through the menu to select RADIO SETTINGS > MIC GAIN.
You can use the or key to increase or decrease the
microphone gain.
NOTE: The Microphone Gain provides a ‘ne’ adjustment to the microphone
sensitivity. A wider adjustment range is available through the XRS Connect App.
SQUELCH TAIL
The Squelch Tail is the short burst of noise that is heard in the speaker at the
end of a transmission just before the Squelch closes. To some it is a reassuring
conrmation that it is their turn to transmit but in some applications it may be an
annoyance especially when listening through an ear piece or headphones.
The Squelch Tail can be turned o, reducing it to a faint click as the Squelch
closes.
To enable/disable squelch tail:
1. Press the MENU key.
2. Navigate through the menu to select RADIO SETTINGS > SQUELCH
TAIL.
You can use the MENU key to turn this function on or o.

XRS-330C
18
ROGER BEEP
The Roger Beep is a tone that is automatically transmitted whenever the PTT is
released. This tone serves to alert the receiving party that your transmission has
ended.
1. Press Menu and select RADIO SETTINGS.
2. Select ROGER BEEP and press Menu to select ON or OFF.
When the Roger Beep tone is enabled, the ROG icon is displayed.
REPEATER AND DUPLEX MODE
Duplex operation allows the radio to transmit on a dierent frequency to that
which it receives. This allows operation through repeater stations.
A repeater station consists of a linked transmitter/receiver combination installed in
a prominent location. The repeater is designed to receive signals on a designated
channel and retransmit them on another channel. Repeaters are usually mounted
on hills or tall buildings. The increase elevation greatly improves both the receiving
and transmitting range of the repeater allowing it to receive and retransmit
signals to radios that would otherwise be out of range of each other.
Normally, UHF CB radios transmit and receive on the same frequency - known as
Simplex operation. However, to communicate through repeaters, your radio must
be able to transmit and receive on dierent channels - otherwise known as Duplex
operation. Your radio is tted with a Duplex key to allow you to operate through
repeaters.
The Duplex function can only be selected on channels 1 - 8 and 41 - 48 as these
are the channels that have been allocated for repeater use. When Duplex is
selected, your radio receives on the selected channel (e.g. CH 1) but transmits 30
channels higher (CH 31). The repeater hears your signal on CH 31 and retransmits
it on CH 1 for others to hear.
Your XRS Connect radio allows you to enable or disable Duplex mode on individual
repeater channels. In this way any repeater channels that are not being used with
repeaters in your area can be used in Simplex mode for normal direct radio-to-
radio communications.

XRS-330C 19
To enable duplex on a repeater channel:
1. Select the required repeater channel (1 - 8, 41 - 48).
2. Briey press the DUP key. The icon will appear on the display
accompanied by a high beep.
To remove duplex from a repeater channel:
1. Select the required repeater channel (1 - 8, 41 - 48).
If duplex is currently selected, the icon will be
displayed.
2. Briey press the DUP key. The icon will disappear
from the display accompanied by a low beep.
NOTE: Channels 1 - 8, 31 - 38, 41 - 48 and 71 - 78 should only be used in Simplex
mode if there are no repeaters in or near your location that operate on the
selected channel. In particular, avoid operating in Simplex mode on any of the
repeater input channels 31 - 38 and 71 - 78 unless you are absolutely sure that
there are no repeaters in range using that channel. Inadvertently transmitting on
an active repeater input frequency in simplex mode could cause interference to
other users on that repeater who might not be audible to your radio.
PRIORITY CHANNEL
The Priority channel feature allows you to instantly recall any one of the 80 CB
channels in your radio. This feature can be used to provide instant access to your
working channel or your local repeater channel at the press of key. It is also used
in conjunction with the Priority Scan mode.
To store a priority channel:
1. Select the required channel.
2. Press and hold the PRI key.
The channel number will ash for a few seconds then a high beep will
be heard as the channel is stored. The ‘PRI’ icon will now be visible
whenever that channel is selected.
NOTE: The Priority channel can also be set through the Menu.

XRS-330C
20
To recall a priority channel:
Briey press the PRI key. The radio will immediately switch to the Priority channel
and the ‘PRI’ icon will be displayed.
NOTE: If the radio was scanning when the Priority channel was recalled, the scan
will be cancelled.
SCANNING
Your radio incorporates a scan function allowing selected groups of channels to be
scanned for signals. Channels can be scanned at a rate of 50 channels per second.
When a signal is found, scanning will pause to allow the signal to be heard then
resume scanning when the channel is clear again.
SCAN GROUPS
Your radio supports three scan groups:
• Open Scan: Allows you sequentially scan from 2 to 80 user-selectable
CB channels.
• Priority Scan: Allows you constantly monitor your priority channel
while scanning a group of user-selectable CB channels.
• Network Scan: Allows a group of radio users to maintain
communications even when the band is congested by monitoring
a small group of user selectable channels. If the operating channel
becomes busy with users from outside your group, Net-Scan will
automatically select a new free channel from the scan group and
transparently switch all users in your group to the new channel.
To select open scan/priority scan/network scan:
1. Press the MENU key.
2. Navigate to select SCAN SETTINGS, and the required scan option.
