Getting Started
Your radio is powered by a specially designed Lithium Ion battery pack.
Handheld UHF-CB Transceiver
The drop-in charger (DT850A/DT850B) can charge
the Lithium Ion battery pack attached to the radio, in
the front charging slot.
The drop-in charger (DT850D) can charge the Lithium
Ion battery pack attached to the radio, in the front and
the back charging slot.
1. Place the radio, in the drop-in charger.
2. The red LED illuminates and stays ON, until fully
charged.
• The charger won’t overcharge the battery packs.
3. The green LED illuminates and stays ON after
charging is completed.
• Do not transmit when the radio is in the drop-
in charger!
•You can monitor incoming calls while the radio is
in the drop-in charger.
Charging the Battery Pack
For the initial battery charge, make sure the radio is off for
NOTE optimum charging.
UNIDEN UH835S/UH850/UH850S
NOTE
UH850S-2TP comes with dual desktop charger, it allows
you to charge two radios at once. Do not charge the
standalone battery pack with the Drop-In Charger (DT850D).
• Before operating the radio, charge the Lithium Ion battery pack for
- up to 4 hours (1-slot type)
- up to 8 hours (2-slot type)
without interruption in the drop-in charger.

Operation
Selecting A Channel
Press or to select the desired channel.
NOTE
If you press and hold or the
channel numbers will scroll rapidly.
To Transmit And Receive
The radio uses the UHF-CB Channels.
For your reference a list of the available
channels and corresponding frequencies
is printed on p.31 - p.32. (Channels 22
and 23 are for telemetry and
telecommand applications, channels 61,
62 and 63 are for future use. TX is
inhibited on these channels.)
The maximum RF transmit power of
UH835S is 3.5W and UH850/UH850S is 5.0W. (see Transmit Power
Select, p.15.)
1. Before you transmit, listen for activity on the selected channel.
2. When the channel is clear;
- Press [PTT] to transmit at the selected Hi/Lo transmit power,
TX appears on the LCD and LED lights red during transmit.
Hold the radio with microphone approximately 5cm 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 [PTT] and listen for a
response then TX disappears on the LCD. LED lights green while
receiving a signal.

Operation
To Operate In Duplex Mode (Repeaters)
Handheld UHF-CB Transceiver
The Duplex function enables you to access local repeater stations.
You can only activate Duplex on CH01-CH08 and CH41-CH48.
NOTE
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.
Eg. CH01 is being used in your area
for repeater use.
1. Press [MENU/MEM] 5 times.
2. Press or to change the selection.
r appears for CH01-CH08 and n appears
for CH41-CH48 when duplex is selected.
3. Press & hold [MENU/MEM] to save and exit.

Scanning
There are 3 scanning modes;
Open Scan (OS),
Group Scan (GS) and
Master Scan (M.SCN) (a special case of Group Scan).
During SCAN the radio only checks channels or frequencies that are
in the SCAN Memory, which are indicated by the M (memory) icon. The
radio maintains two SCAN Memories; one for Open Scan (OS) mode
and the other for Group Scan (GS) mode, to give you flexibility and allow
you to use the radio more effectively.
Group Scan and Master Scan modes share the same SCAN

UNIDEN UH835S/UH850/UH850S
Open Scan (OS) Mode
Open Scan is the default scan mode.
All UHF-CB have been added to the OS SCAN Memory for convenience.
To add/remove channels from OS SCAN Memory, refer to p.17.
Allows continuous scanning of all selected channels. If an active channel
is found, scanning will stop on that channel. If the received signal
ceases, the unit will wait 2 seconds for the signal to return, otherwise
scanning resumes.
After transmission in scan mode, the scan mode will be cancelled.
To select OS scan mode,
Press and hold the [SCAN| OS/GS/MS] key.
NOTE
OS Mode is indicated by the absence of the
GS and M.SCAN icons.
NOTE
If SCAN is deactivated while on an active channel, the
radio will stay on that active channel. If no channels are
active, the radio will reinstate the starting channel.

Operation
UNIDEN UH835S/UH850/UH850S Handheld UHF-CB Transceiver
Group Scan (GS) Mode
GS Mode has CH09 to CH20 in the SCAN Memory by default. Channels
must be stored to the GS SCAN Memory before group scan can start.To
add/remove channels from GS SCAN Memory, refer to p.17.
Includes the accessory feature Priority Watch which allows you to
monitor the Instant Priority Channel while scanning (see p.22 for setting
Instant Priority Channel and p.22 to turn on Priority Watch).
If scanning stops on a channel which is not a Priority Channel, UHF
CB Radio will continue monitoring the Priority Channel for activity while
listening to the active one.
To select GS scan mode,
Press and hold the [SCAN| OS/GS/MS] key. GS icon appears on the
display.

19 Handheld UHF-CB Transceiver
Operation
UNIDEN UH835S/UH850/UH850S
MASTER SCAN Mode
MASTER SCAN allows continual communication across congested
channels.
Master Scan scans channels stored into GS Memory and only opens the
squelch for signals with the correct subcode (CTCSS or DCS tone).
To achieve this, all radios in your group must have the same channels
in GS memory (group channels) and use the same Subcode (CTCSS or
DCS tone).
By scanning only group channels, radios in the network will be able to
detect and receive group transmissions- continual communication with-
out interruption. When transmitting in this mode, the radio switches to an
unused group channel if it detects another signal with no code, or the
wrong code, on the channel last used by the group. In this way, all group
users will be able to have continual communication to or from other
users.
CH09-CH20 are stored into GS Memory and CTCSS01 is set for
MASTER SCAN Subcode by default. The GS memory can be changed,
channel by channel, if desired, but for Master Scan to work effectively
each radio in the group must have the same channels in its GS memory.
To add/remove channels from GS SCAN Memory, refer the section
above.
