CAUTION
Avoid exposing the Lithium Ion battery, attached or
unattached to the radio, in direct sunshine, heated cars, or
in areas with temperatures below –20°C (–4°F) or above
+60°C (+140°F).
Exposing the chemicals contained within the battery pack to
temperatures above +60 °C (+140°F) may cause the battery
to rupture, fail or reduce performance.
In case of exposure to cell contents, wash the affected area
thoroughly, and seek medical attention.
Additional battery cautions should be applied as described
on p.2.

Charging the Battery Pack
Your radio is powered by a specially designed Lithium Ion battery pack.
• Before operating the UH078SX-NB, charge the Lithium Ion battery
pack for 5 hours without interruption in the drop-in charger or 3.5
hours without interruption in the cigarette lead charger.
NOTE
For the initial battery charge, make sure the radio is off for
optimum charging.
The drop-in charger can charge the Lithium Ion
battery pack attached to the UH078SX-NB in the front
charging slot and also charge a second Lithium Ion
battery pack separately in the rear charging slot.
When you charge the 2nd battery, be sure to push it
all the way into the charge slot.
1. Place the UH078SX-NB in the drop-in charger.
2. The red LED illuminates and stays ON, until fully
charged.
• The charger won’t overcharge the battery packs.
When charging is completed, the charge LED
is no longer illuminated.
• Do not transmit when the UH078SX-NB
is in the drop-in charger!
• You can monitor incoming calls while the UH078SX-NB is in the
drop-in charger.

Operation
To Transmit and Receive
The UH078SX-NB uses the UHF-CB Channels. For your reference a list
of the available channels and corresponding frequencies is printed on
p.28-p.29.
NOTE
UHF-CB Channels 22 and 23 are for telemetry and
telecommand applications. Transmit is inhibited on these
channels.
1.The maximum RF transmit power of UH078SX-NB is 5 Watts.
Press TXP to change the transmit power
between High(5W), Middle(1W) and Low(0.5W).
HI appears when on high power. LO appears
when on low power. HI and LO disappear when
on middle power.
2.Before you transmit, listen for activity on the
selected channel.
3. When the channel is clear, press and hold the
PTT to transmit. TX appears on the LCD.
Hold the radio with microphone approximately
five cms in front of your mouth with the
antenna at approximately 45* angle away from
your head. Speak in a clear, normal
conversational voice.
4. When you have finished speaking, release the
PTT and listen for a response. TX indicator
then disappears on the LCD.
The display shows BUSY when a transmission
is being received by your radio.

Handheld UHF-CB Transceiver
Operation
Using a Repeater Channel
UHF-CB Repeaters are used to retransmit or relay your signal.
Repeaters will extend the range of your radio and overcome the
shielding effect caused by solid obstructions.
In normal Simplex operation, your radio transmits on one particular
frequency and receives on that same frequency. If there is a barrier (i.e.
a Tall Building) that partially blocks your transmitted signal, the possibility
of the other radio receiving the signal is very slim. Valleys, metallic
structures, etc., tend to act as a screen between radios.
Standard Operation without the aid of a Repeater Station
Operation with the aid of a Repeater
With Duplex operation, the signal coming from your radio is received
by the Repeater station and then re-transmitted at the same time on
another channel.
Your UH078SX-NB is designed with duplex capability on Channels 1 to 8
and Channels 41 to 48. When any of these channels are set to operate in
duplex mode during transmission, the UH078SX-NB automatically sends
the signal at a frequency 30 channels above the original in order to access
the repeater station. After transmitting, the radio reverts back to its original
operating frequency.
For example:
1.CH01 is on Duplex Mode - will receive on CH01 but transmit on CH31
2.CH02 is on Duplex Mode - will receive on CH02 but transmit on CH32, etc... Refer to UHF-CB Channel & Frequencies table on p.28 - p.29.

Scanning
The UH078SX-NB has two types of scanning; Open Scanning (OS)
and Group Scanning (GS). Scanning allows you to search for active
channels programmed in the OS or GS memory.
To initiate scanning;
1. Assuming the unit is on CH17 when switched on.
2. Press scan and scanning starts. SCAN icon
appears during scanning.
The scan direction can be changed at any time by pressing
or
.
Open Scan (OS) Mode
The absence of GS icon indicates that the unit is in OS mode. Allows
continuous scanning of channels stored in the Open Scan (OS) memory.
If an active channel is found, scanning will stop on that channel.
NOTE
The factory has preprogrammed all the UHF-CB channels
into the Open Scan channel memory. However, you can
change or customize the channels by following the steps on
programming Scan Channels on page 20.
Example: CH40 becomes active
If the received signal cease, the unit will wait for at least 3 seconds for
the signal to return, otherwise scanning resumes.

for as long as the signal is present. If the received signal ceases, Priority
scanning continues after 3 seconds.

UHF-CB Channel Guidelines
NOTE
Always listen on a channel (or observe the receive signal level
meter) to ensure it is not already being used before transmitting.
Channels 5 and 35 are used for emergency channels.
CTCSS and DCS will not operate on these channels.
Please follow these guidelines for channel use in Australia:
• Channels 05 and 35 are Emergency Channels.
• Channel 11 is a Calling Channel.
• Channels 22 and 23 are for telemetry and telecommand
applications and TX is inhibited on these channels.
General communication is accepted on all other channels
with these guidelines:
• Channel 40 - road channel (Australia).
• Channels 01-08 (and 31-38), and Channels 41-48
(and 71-78) are repeater channels.
Important information - 80 Channel UHF-CB channel expansion
To provide all users additional channel capacity within the UHF-CB
Band. The ACMA will change the majority of the current wideband 40
channel use to narrowband channel use. This allows for additional
channels to be added, up to 80 (77 usable) Channels.
This simply means that the new narrowband radio you have purchased
will have more channels than older radios. Please refer to the guidelines
above and the channel chart for further channel information.
A list of currently authorised channels can also be obtained from the
ACMA website in Australia and the MED website in New Zealand.
NOTE
Interference / Poor Audio
When a new narrowband radio receives a signal from an older
wideband radio the speech may sound loud - however the UH078SXNB’s built-in AVS (Automatic Volume Stabilizer) circuitry will detect
and manage incoming audio to comparable levels.
Narrowband radios operating on CH41 - CH80 may encounter
interference from a nearby wideband radios transmitting on high
power on an adjacent channel (frequency).
When an older wideband radio receives a signal from a new
narrowband radio the speech may sound quiet - the wideband radio
user simply adjusts their radio volume for best performance.
The above situations are not a fault of the radio but a symptom of mixed
wideband and narrowband radios in current use. It is expected that as
older wideband radios are phased out this issue will be eliminated.
