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 Iow
power, press the
HI/La switch. LOW
appears on the LCD
and the transmit
power output level is
changed to 0.2

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 £hannel
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 (Le. Valley) that partially blocks your
transmitted signal, the probability of another
radio receiving the signal is very slim. Valleys,
tall buildings, metallic structures, ...etc., tend
to act as a screen between radios
StandardoperationwithoutthehelpofaRepeaterStation
OperationwiththeaidofaRepeaterStation
iJ)) ~j ~11

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) CH01 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 CH01 Duplex mode, you are
actually transmitting on CH31, the repeater
station down-converts your signal and
retransmits on CH01.
TO operate UH-O54 in Duplex Mode
egoCH01 is being used
in your area for
repeater use.

icon appears.

Dual Watch
Dual Watch mode monitors a priority channel
and the currently selected channel for a signal.
The UH-O54 checks the priority channel for
activity every 1.5 seconds.
Selecting aPriority Channel
The UH-O54 is pre-
programmed with
CHO1 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
channel (e.g. CHO4)
3. Press and hold the
priority button to
change the new
channel to priority.
You hear a beep and Pappears on the
LCD.

You can begin dual
watching by simply

priority channel is checked. 13

While in Dual Watch Mode, you can use the..
or T to change to a new selected channel
while monitoring the priority channel.
To cancel dual watch, momentarily press
priority button or the PTT.
Scan
Your UH-O54 has a scanning feature that
.allows you to search for active channels
automatically.
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. M:~c~a855
3. When it finds
(receives) an active

054 stops and
monitors that
channel.

Priority Channel Scanning
Priority Channel Scanning allows you monitor
the priority channel while scanning.
There are two ways to begin priority Scanning.

Deleting and Storing 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'" or ... button
manuallyselect the
unwantedchannel.
2. Then press and hold
the mem button.
You will hear a two-
confirmation tone
and MEM icon
disappears from the
display.

Drop Out delay
While scanning, the UH-O54 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 LCDback 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
level indicator is
always the current
battery level when
not in Squelch
or Volume Adjust
Mode.
2. The battery level
indicator indicates
the current battery
voltage level.

3. If 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.
