Channel Scan
UP
W/hen you pressed the O Key for more than 1.5 seconds,
the scan feature starts and the SCN indicator appears on
the LCD.
Scanning stops automatically on any active channel that is
not Locked-out, receives a call and you hear the caller.
To resume scanning, press the Q Key.
UP
If there is too much activity on a certain channel and you
w^h to exclude it from being scanned, simply press the
O Key when on that channel. It will be automatically
removed from the scan list, and scanning resumes (please
see page 12 on how to create a channel scan list).
Pageii
UH-056
To disable scanning:
iXMN
- when on an active channel, press the O Key and
the unit stays on the active channel.
U3=> DCWN
- while scanning, press the O or O Key. The unit
returns to the channel where scan function is acti
vated.
- press the PTT switch. When the unit is on an active
channel, it transmits on the same channel.
When scanning, the unit transmits on the channel
where scan function is activated.
SCN indicator disappears from the LCD Display,
Drop Out Delay
While scanning, the radio stops at a busy channel and
receives a transmission. When the received call is over, the
unit will wait for three seconds for the return of the signal.
Otherwise it resumes scanning.
Create a Channel Scan List with Channel Lock-Out
Feature
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 Lock-out those channels so they are not scanned.
There are two ways to exclude channels from being
scanned:
1. UsingtheOoi" O switches, manually select the
DP OOM4
uo
desired channel and press the O button. The lockedout channel blinks.
2. While scanning, when the unit stops on the channel you
wish to lock-out because of its too much activity, simply
VO
press the O Key and it will be automatically removed
from the scan list. Scanning resumes.
To remove the lock-out condition from a channel, manually
(JO
select the channel and press O button again. The channel
stops blinking.

TRANSMIT
1. The maximum transmit power output level ot UH-056 is
5 watts.
To switch to low power, press the HI/LO switch. LO
appears on the LCD and the transmit power output level
is changed to 1 watt.
To switch back to High power, press the HI/LO switch
again. The TX power returns to high and the LO
indicator disappears from the LCD.
2. Before you transmit, listen for activity on the selected
channel.
3. When the channel is dear, press the PTT switch to
transmit. The TX LED comes on when you transmit.
Hold the radio with the microphone approximately two
inches in front of your mouth with the antenna at
approximately a 45-6egree angle away from your head.
Speak in a dear, normal, conversational voice.
4. When you are finished speaking, release the PTT switch
and listen for an answer.
Simplex / Duplex Communication
Duplex Operation allows the Uniden Sundowner UH-056 to
operate via a repeater station on Channels 1 through 8.
The set receives on these channels but transmits on
Channels 31 through 38 respectively.
When Duplex operation is disabled, the set receives and
transmits on the same channel. (Simplex Communication)
To activate Duplex operation on a Channel where Repeater
Service is available, select the channel and then press the
O button, DUP indicator appears on the LCD Display,
To put the Duplex programmed channel back to normal^
Simplex operation, select the channel and press the O
button again. DUP indicator disappears from the LCD
Display.
Page 13UH-056
Low Battery Level Detection
Uniden Siindowner UH-056 has a built-in battery level
detector circuit. It evaluates your Battery Pack everytime
you transmit to determine whether the power inside the
Battery is still sufficient enough to support normal Receive
and Transmit communications.
The circuit will inform you in two ways.
1, When the PIT switch is pressed and the TX LED blink;
It means the battery level is already low and needs
recharging. You can still transmit, however, you must
finish the conversation and have your battery charged
fully to resume normal operation.
2. When the Blinking TX LED went unnoticed and the
Battery goes down to where normal communication car
no longer be supported, the circuit will disable the PTT
switch and emit an error tone everytime you try to
transmit.
