Charging the Battery Pack
Your UHF CB radio is powered by a speciallydesigned nickel-cadmium battery pack.
Before operating the UH-054, charge the
battery pack for 15 hours in fhe drop-in
charger.
1, Place the UH-054 in the drop-in charger.
Si.
2. The red LED lights and stays on.

Transmitting
The UH-054 uses the 40 UHF CB Channels.
For your reference, a listing of all the available
channels is printed at the end of this manual.
1. The maximum RF transmit power of UH-
054 is 1 watt.
To switch to low
power, press the
FII/LO switch. LOW
appears on the LCD
and the transmit
power output level is
changed to 0.2
Watt.
To switch back to
high power, press
the Ftl/LO switch
again. TheTX
power returns to
high and the LOW
indicator disappears
from the LCD,
2. Before you transmit, listen for activity on the
selected channel.

MEM LOW ^
. ^ u
3. When the channel is clear, press the PTT
switch to transmit. TX appears on the LCD
when you transmit. Hold the radio with the
microphone approximately two inches in
front of your mouth with the antenna at
approximately a 45-degree angle away from
your head. Speak in a clear, normal
conversational voice.
4. When you are finished speaking, release
the PTT switch and listen for an answer.
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. Valley) that partially blocks your
transmitted signal, the probability of another
radio receiving the signai is very slim. Valleys,
tall buildings, metallic structures,... etc,, tend
to act as a screen between radios
Standard operation withoit the help of a Repeater Station
The signal coming from your radio is received
by the Repeater station and then retransmitted
at the same time on another channel. This
operation is called "duplexing".
Your UH-054 is designed with the capability to
access and use repeater stations.
Channels 01 through 08 have the option to
operate in Duplex Mode, When any of these
channels are set to operate in duplex mode
during transmission, the UH-054 automatically
sends the signal at a frequency 30 channels
above the original. After transmitting, the radio
reverts back to its original operating frequency.
For example,
(1) CHOI on Duplex Mode will Receive on
CH 01 but Transmit on CH31
(2) CH02 on Duplex Mode will Receive on
CH 02 but Transmit on CH32 etc....
If you transmit on CHOI Duplex mode, you are
actually transmitting on CH31, the repeater
station down-converts your signal and
retransmits on CHOI.
TO operate UH-054 in Duplex Mode
eg. CHOI is being used ^
in your area for
repeater use. V
Press DUPLEX
momentarity. The DUP
icon appears.
Press DUPLEX again
to deactivate the
duplex operation.
UH-054 will return to
simplex operation.

Dual Watch
Dual Watch mode monitors a priority channel
and the currently selected channel for a signal.
The UH-054 checks the priority channel for
activity every 1.5 seconds.
Selecting a Priority Channel
The UH-054 is pre
programmed with
CH01 as the priority
channel.
However, you can change the priority
channel to be any other channel.
Note: When you select a new priority
channel, the old priority channel
automatically becomes a regular channel.
1. The radio should be in Stand-by mode.
2. Select the new I
channel (e.g. CH04) ^
3. Press and hold the
priority button to A
change the new I
channel to priority.
You hear a beep and P appears on the
LCD.
Dual Watching
Select a channel other
than your priority
channel, (eg. CHOI)
You can begin dual
watching by simply
pressing priority
button momentarily.
Notice that the display
toggles between the selected and the priority
channel and PRI appears every time the
priority channel is checked.

Memory Scanning
Memory Scanning scans only the channels
stored in the scan memory.
1. To begin scanning,
momentarily press
the scan button.
2. The SCAN icon
flashes as the UH-
054 looks for a
transmission.
3. When it finds
(receives) an active

054 stops and
monitors that
channel.

Deleting and Sforin^ Channels in the Scan
Memory
You may have certain channels that you do not
want to hear every time you scan. These are
channels that are busy in a major portion of
time, and the scanning stops at that channel(s)
often enough to interrupt the scan cycle. You
can remove those channels from the scan
memory so that they are not scanned.
1. Using A or ▼ button
manually select the
unwanted channel.
2. Then press and hold
the mem button.
You will hear a two-
confirmation tone
and MEM icon
disappears from the

Drop Out delay
While scanning, the UH-054 stops at a busy
channel and receives a transmission. When
the received signal is over, the unit will wait for
three seconds for the return of the signal,
otherwise the radio resumes scanning.
Lighted Display
The LCD back light automatically switch-on
every time a key is pressed.
Key Lock
To prevent accidental entries, you can lock the
keypad.
Press and hold the HI/LO button until it
beeps to activate Key Lock.
To unlock the keypad, press and hold the
HI/LO button again.
Note: When the Key Lock is active, a two-
tone warning beep will be heard if you
attempt to use it.

Battery Level Detection
1. At Power On, the

2. The battery level
indicator indicates
the current battery
voltage level.

3. It level 1 is detected when [PTT] SW is
pressed, transmit mode will fail, PTT Error
Tone will sound and TX icon will blink. On
the other hand, if Level 0 is detected,
transmit mode will fail causing PTT Error
Tone to sound while TX icon remains Off.
Once the battery level dips below Level 0,
Power will be turned off automatically.
Once any of the above conditions occur, re
charge your battery immediately.
