Handheld UHF-CB Transceiver

Operation
Squelch
The squelch is used to eliminate the annoying background noise when there is no signal present on a channel. The squelch circuit does this by controlling when the radio’s speaker turns on, based on the strength of received signals.

NOTE

Make sure to first select a channel not in use before setting the squelch in your UH825 UHF-CB radio.

The Auto Squelch feature has 0-5 preset squelch levels:

0 – max sensitivity (min squelch): Speaker is ON. 2 – med sensitivity (med squelch): Default setting. 5 – min sensitivity (max/tight squelch): Less interference. It requires no adjustment.

To set the Squelch level: 1. Press [MENU/MON] 2 times to enter the squelch setting list.
2. Press [ ] or [ ] to select the desired squelch level 0-5.

Strong Signals Medium Signals Weak Signals Noise

3. Press & hold [SCAN/MEM] to save the setting.

NOTE

If an incoming signal is very weak there is a possibility that you will have a choppy or broken reception, due to the sensitivity of the squelch. In this case, adjust the squelch level accordingly.

Handheld UHF-CB Transceiver

Operation

Call Function
The Call function transmits a short “wake up” tone to notify other users of impending communication. You may select from 5 types of tones (see Call Tone (Selecting a Call Tone) on page 22).
To use the Call function: 1. Before you use Call, make sure the channel is not in use. 2. Long press [–] Smart Key until [Cal] appears, then press to make Call and the Call Tone will be transmitted.

NOTE

Current regulations require calling tones to be restricted to one transmission per minute. If a second transmission is attempted within one minute then an error tone will sound.

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

UNIDEN UH825

15

Handheld UHF-CB Transceiver

Operation
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.
For example: 1. CH01 is on Duplex Mode – will receive on CH01 but Transmit on CH31 2. CH41 is on Duplex Mode – will receive on CH41 but Transmit on CH71,
etc… Refer to UHF-CB Channel & Frequencies table on p.28 – p.29.
If you transmit on CH01 Duplex mode, you are actually transmitting on CH31, and the repeater station down-converts your signal and retransmits on CH01.
To Operate in Duplex Mode (using a Repeater)
Only channels 01 – 08 and 41 – 48 are available for Duplex. 1. Press [MENU/MON] 8 times.
2. Scroll down the list to DUPLEX MODE.
3. Select channel 01 – 08 in duplex mode, display as R1 – R8.
4. Select channel 41- 48 in duplex mode, display as N1 – N8
5. Save the setting by pressing and holding [SCAN/MEM].

Icon appears on the channel when Duplex setting is enabled for a duplex capable channel.

Handheld UHF-CB Transceiver

Operation

Scanning

The scan feature allows you to search for active channels automatically. You can only scan channels that are stored in the Scan memory. The UH825 has eight Scan modes;
· Open Scan (OS) · Group Scan (GS) · Memory Scan (MS) · Preset Scans: P1, P2, P3, P4 Indicated by the SC or GS icon on the LCD. A channel is stored in the scan memory of the current scan mode when the [M] icon appears beside the channel number.

By default the UH825 is set to OS scan mode with all UHFCB channels stored into the OS channel memory. The GS scan memory by default is stored with Ch09-20 channels but can be customized according to User’s choice.

NOTE

You can change or customize the channels stored in OS or GS scan momory by following the steps on Add/Remove Channels from SCAN Memory on page 18.

What is Open Scan (OS) Mode? OS is the default scane mode which scans all memory (MEM) channels in the OS scan memory. If an active channel is found, scanning will pause on that channel while there is a signal.
What is Group Scan (GS) Mode? GS allows you to monitor the default stored channels or the user defined stored channels along with Priority channel (if enabled) for scanning.
What is Master Scan (MS) Mode? Master Scan when enabled allow continual communication across congested channels. Master Scan scans group of different set of stored channels and only opens the squelch for signals with the correct subcode (CTCSS or DCS tone).

NOTE

If GS Scanning is initiated when there are no channels programmed in GS scan memory, an error tone will be heard and scanning will not start.

Save the setting by pressing and holding [SCAN/MEM].
Add/Remove Channels from SCAN memory
1. Select the Scanning mode as explained above and exit the menu by pressing PTT.
2. Press [ ] or [ ] to select the channel you want to store. 3. Press and hold [MEM] for 1.5 sec to store.
“M” icon appears near to that channel and a short tone beep is heard. 4. To remove the channels from Memory:
Press and hold [MEM] for 1.5 seconds once more. A short tone beep is heard and the “M” icon disappears.
To Start Channel SCAN
1. Press [SCAN] and the radio will begin scanning the channels that are in the OS or GS memory – depending on which of these is currently active. SCAN icon flashes during scanning. Press [PTT] to return the original set channel.
Scan Direction SCAN will begin scanning for active channels in a sequential order. You can change the scan direction (increasing or decreasing channel number) by pressing [ ] or [ ].

UNIDEN UH825

Handheld UHF-CB Transceiver

Operation

Drop-out delay When SCAN finds a busy channel it pauses scan to receive the signal. When the received signal stops, the radio waits for 3 seconds for the return of the signal, otherwise, the radio resumes scanning. Recent Active Channels SCAN remembers recent active channels and monitors these channels for activity while scanning through the scan memory. This means if recently active channels become active again during SCAN, the radio will pause on these channels first. This makes scanning for active channels more efficient (faster) the longer SCAN is operating. Skipping an Active Channel When paused on an active channel it is not possible to skip this channel as the recent active channel feature will cause scan to lock back onto that active channel. Wait for the active channel to become inactive and SCAN will resume. If you want to avoid an active channel completely, deactivate SCAN and remove the channel from the scan memory, then reactivate SCAN. Priority Channel in GS Mode In GS mode, if the the Priority channel is enabled, the scan will also include the set Priwatch Channel along with the stored channel. Radio will automatically pause on the priority channel when it gets active. By disabling the Priority Channel, It will not included in scan. (see p.21) 2. To deactivate SCAN, press [SCAN] . 3. During the MASTER SCAN, reception is only possible if the MASTER CODE (CTCSS/DCS) is set with the same code on both the radio devices using the same stored communication channel.

If SCAN is deactivated while it is tuned to an active channel, the UH825 will stay on that active channel.

NOTE

If SCAN is deactivated while in-between active channels, the UH825 will reinstate the last active channel.
If SCAN is deactivated when no active channel has been found, the UH825 will reinstate the starting channel.

UNIDEN UH825

Handheld UHF-CB Transceiver

Operation
Master Scan
It allows continual communication accross the congested channels.
Master Scan scans the channels stored into Group Scan (GS) memory and only opens the squelch for signals with the correct Master Code (CTCSS/DCS).
To achieve this, all radios in your group must have tuned the same set of channels stored in the GS memory and enabled with the same Master code.
By scanning only the selected group channels with common enabled master code, radios in the network will be able to detect and receive group transmission in continuous manner without any interruption. When transmitting in this mode, the radio auto switches to an unused group channel with no code, or the wrong code. In this way, all group users will be able to have continual communication to or from other users.
The default mode for Master Scan is set with the stored channel from CH09-Ch20 with the master code CTCSS01. The group scan 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 the GS memory.
Refer to P.18 to see how to add/remove channels from the Scan memory.

NOTE

RX only channels (CH22, CH23, CH61, CH62 and CH63) will not be included in MASTER SCAN mode even though stored into GS memory. Also channels for which the duplex setting are ON will be skipped in MASTER SCAN mode.

CTCSS / DCS

CTCSS (Continuous Tone Coded Squelch System) The CTCSS squelch codes allows a group to talk to each other without hearing other users on the same channel. The group needs to use the same code. And as there are 38 CTCSS codes available the chances of nearby users using the same code is unlikely.
DCS (Digital Coded Squelch) DCS is a digital version of CTCSS. It provides 104 extra, digitally coded squelch codes that follow after the 38 CTCSS codes. Follow the steps for changing CTCSS code but select a DCS code as desired.

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 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.

NOTE

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 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.
Interference / Poor Audio
When a new narrowband radio receives a signal from an older wideband radio the speech may sound loud. 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.
