Getting Started

Mobile Station Installation

Select the location of the transceiver and microphone bracket before starting the installation. The location should be convenient and should not interfere with the driver or passenger in the vehicle. The transceiver should be securely fastened to a solid face, using the mounting bracket and self-tapping screws which are provided.

Choosing an Antenna

Since the maximum allowable power output of the transmitter is limited by the

Spectrum Management Agency (SMA), the antenna is a very important factor for transmission distance. For this reason, the installation of a quality antenna is strongly recommended.

The SundownerUH-O99 is a superior transceiver, however, installing an inferior antenna may cause a reduction in performance.

Only a properly matched antenna system will allow maximum power transfer from the

50-ohm transmission line to the radiating element. Your Uniden dealer is qualified to assist you in the selection of a compatible antenna to meet your application requirements.

For automobile installation, the whip antenna is recommended.

The most efficient and practical installation is a full quarter wave whip antenna mounted on the rear deck midway between the rear window and bumper.

A short "loaded" whip antenna is easier to install on an automobile.

However it is not as efficient as a full quarter wave whip antenna.

For marine installation, consult your dealer for information regarding an adequate grounding system and prevention of electrolysis between fittings in the hull and the water.

Ground System

Connect the red DC power cord from the transceiver to the positive (+) battery terminal or another convenient point and connect the black power lead to the vehicle frame, or the negative (-) battery terminal.

Page 6

Operation

How to Receive

1.

Confirm that the power source, antenna, and microphone are connected properly before proceeding to the following steps.

2.

Turn the unit ON by rotating the VOLUME control clockwise.

3.

Set the CHANNEL CONTROL knob to the desired channel.

4.

5.

Set the VOLUME control to a comfortable listening level.

Listen to the background noise from the speaker. Turn the SQUELCH control slowly clockwise just until the noise is eliminated (no signal should be present).

Leave the control at this setting. The Squelch is now properly adjusted. The receiver will remain quiet until a signal is actually received. Do not advance the control too far, or some of the weaker signals will not be heard.

How to Transmit

1.

Carefully read the SMA Rules and Regulations prior to operating the transmitter.

2.

Select the desired channel.

3.

To transmit, press the PRESS- TO-TALK button on the microphone.

Hold the microphone 2-4 inches from your mouth and slightly to one side so that your voice does not project directly into the microphone (this provides the best results).

Speak at a normal level. Never raise your voice or shout into the microphone.

Whenever the PRESS- TO-TALK button is pressed, the TX indicator will light.

Open Scanning

To commence open scanning, select the OPEN SCAN mode by pressing the OSlGS button when in GS mode. Then press the SCAN button.

The SUNDOWNER UH-099 will commence scanning the programmed channels, and will indicate each channel on the CHANNEL indicator as it is scanned.

When a busy channel is found, the radio will 'lock' onto it, and will remain there for as long as the signal is present, and for 3 seconds after the transmission ceases. This allows the SUNDOWNER UH-099 to hold the channel during short breaks in the conversation.

Once the channel has remained clear for 3 seconds, the radio will resume scanning.

If you do not wish to listen to a busy channel, you can SKIP over it by pressing the MEM button on the radio. The receiver will immediately resume scanning.

The SCAN MODE will be cleared when the PRESS- TO-TALK BUTTON is pressed.

NOTE:

1. During the OPEN SCAN mode, the CHANNEL SELECTOR knob is ignored.

2. The scan rate in this mode is 0.1 second per channel. In other words, all

40 channels can be scanned in 4 seconds.

Page 9

Group

Scanning

Tocommence

GROUP SCANNING, select the GROUP SCAN mode by pressing the

OS/GS button when in the OS mode, and select the SCAN mode by momentarily pressing the SCAN button.

The SUNDOWNER UH-O99 will now scan the programmed channels, displaying each channel number and the PRIORITY channel number. Before it scans each channel, it quickly "checks" the PRIORITY channel (set by the CHANNEL SELEC-

TOR).

NOTE: 1. In the GS mode, the starting channel prior to GS Memory Scanning is always set as the Initial PRI Channel.

2. If the GROUP SCAN memory has not been programmed when the

GROUP SCAN mode is selected and the SCAN button has been pressed, the SUNDOWN ER UH-O99will emit an error tone.

3. The PRIORITY channel number can easily be read when necessary by:

(a) Simply turning the Squelch knob counter-clockwise until the squelch opens. After checking, return the Squelch knob to the previous position.

(b) Pressing the PRESSTO-TALK button, the unit will transmit on the

PRI channel and scanning will be cancelled.

Press the SCAN button to resume scanning.

Receiving

a Signal on a Group Scan Channel

If a signal is received on a programmed scan channel, the radio will 'lock' onto that channel

provided there is no signal on the PRIORITYchannel.

When the receiver is 'locked' onto the scan channel, the LCD Channel Indicator will switch between the scan channel and the PRIORITY channel. This is because the receiver is still 'listening' for signals on the PRIORITY channel.

When the scan channel becomes quiet again, the radio will continue to hold the channel for another 3 seconds in order to allow for a natural pause inthe conversation before resuming the Group Scanning mode.

If there is a transmission on the PRIORITY channel while you are listening to a scan channel, the receiver will immediately transfer to the PRIORITY channel and the

PRIORITY channel number will be displayed.

To RESUME scanning, while receiving a signal, momentarily press the MEM button on the front panel. The receiver will resume scanning.

To stay on the current active channel, momentarily press the PTT button. The Scan

Mode will be cleared.

Page 10

Removing Open Scan Channels

When the radio is initially turned on, all 40 channels are programmed in the OPEN

SCAN MEMORY.

If you do not wish to scan some particular channels (e.g. if one or more channels are continually busy and always causing the scanning function to pause), you can remove these channels from the scan group by using the following procedure:

1.

Cancel scal)ning (if active).

2.

Select the OPEN SCAN mode by pressing the OS/GS button when in the GS mode. The OS indicator should appear. The GS indicator should not appear.

3.

Rotate the CHANNEL SELECTOR knob until the channel you wish to remove is displayed on the CHANNEL INDICATOR.

Note that the MEM indicator is lit, indicating that this channel is currently included in the scan group.

4.

Press and hold the MEM button for about 1.5 seconds until a beep is heard twice.

Selective Calling

Outline

Selective Calling (SELCALL) is a special Sequential Tone Squelch System that allows the user to receive/transmit calls selectively from/to an individual or a group, on a shared busy channel.

The SUNDOWNER UH-O99 has a specially built-in Selective Calling (SELCALL) system. Exceptional features like Receiver Quieting, Tone Squelch Scanning, Tone and Group Calling make the SUNDOWNER UH-O99superior to any transceivers in its class.

Receiver Quieting (Tone Squelch)

When activated, automatically mutes the receiver audio circuit of the radio. It will stay in this "Quief' mode as long as the SELCALL tone code (SELCALL ID) required to open the muting circuit is not received.

Call Alarm

When a received code matches to your SelcalllD, an alarm will be emitted informing you that a caller is on the channel.

Tone Squelch Scanning

Scans only Tone Squelched Channels.

Tone Calling

Allows you to selectively call other radios.

Group Calling Capability

Transmits and Responds to Group Calls.

Page 13

Receiver Quieting

Puts

the receiver in the "Ouiet" mode (also known as the "Tone Squelch" mode). When activated, the transceiver prevents any unwanted conversations in the channel from being heard unless the call is specifically directed to you and the SELCALL ID required to open the "Ouiet" condition has been received.

To activate:

1.

Select the channel you want to put in Quiet mode using the Channel Selector knob.

2.

Press the T.SO button for about 1.5 seconds. One beep is heard and the T.Sa

indicator appears on the LCD display.

Under this condition, the PRESS- TO-

TALK button is temporarily disabled.

If you wish to use the same channel for normal communication simply remove the channel from Quiet mode.

Note: Channels that are stored in either OS or GS (MEM), when put in the Quiet condition, will be skipped during OS/GS Memory Scanning

If GS Scanning is used and the starting channel is a T.SO Channel, the PRI

Channel will not be set. Rotate the channel knob to set a new PRI channel.

To deactivate the Quiet Condition:

1.

Manually select the Tone Squelched Channel.

2.

Press the T.Sa

button for about 1.5 seconds.

Two beeps are heard and the

T.SO indicator disappears from the LCD display.

Call Receiving

While in the T.SO condition, when UH-099 receives a code matching your

SELCALL ID, it will perform the following operations:

1.

Automatically responds to the caller by transmitting Acknowledge Tones.

2.

Informs you that a caller is on the channel by emitting a CALL ALARM (Default

Alarm Setting: four successive beeps in a regular interval for 10 seconds. Refer to "Programming Method" for other alarm settings) and displays the CAL indicator.

3.

Flashes the T.SO indicator for about 20 seconds allowing you to use the

PRESS-TO-TALK button. Ifyou are not be ableto respondwithin the 20 second period, T.SO stops flashing and Quiet mode resumes.

Tone Squelch Scanning

If you are using two or more channels in the T.SO mode, you can monitor all of these channels for selective calls by using the T.SO Scanning feature.

To use this feature:

Page 14

Start the T.Sa Scan by pressing the T.Sa button during Open Scan or Group

Scan.

Unlike Normal Scanning, T.Sa

Scanning checks the detected carrier for

SELCALL information. If this information is not found, T.Sa scanning resumes.

When a call is received during T.Sa Scanning, UH-099 follows the same response as when receiving a call on a Tone Squelch Channel. It differs only in the following ways.

1.

If the call is not answered within the 20 second period, T .sa Scanning resumes.

The CAL indicator remains on the LCD.

To look for the channel where CALL is received: a. Cancel T .sa

Scanning by pressing the Scan button.

b. Using the Rotary button, browse through the T.Sa Channels.

The CAL indicator marks the channel where the call is received.

2.

When answered, T.Sa scanning is automatically deactivated.

The channel is removed from the auiet Operating mode.

To deactivate T.Sa Scanning:

1.

Press the T.Sa button. The unit returns to the Normal Scanning Mode, or

2.

Press the Scan button. The whole scanning operation is cleared.

3.

When a SELCALL is received, press the PRESS-TO-TALK button.

Note: The chance of receiving and decoding SELCALLs effectively during T.Sa

Scanning can be increased in manydifferent ways. You can either decrease the number of channels to be scanned thus increasing the scanning speed, or change some of the SELCALL parameters (refer to "Other SELCALL

Parameters" on page 21).

Be sure that each member of your group uses the same configuration, otherwise, the chance of selectively calling each other will be decreased.

Tone Calling

Tone Calling allows you to selectively call other radios.

To do this, the SELCALL ID of the radio you are going to call should be in the

Transmitter's SELCALL ID memory (refer to "5/6 Tone TX SELCALL

Programming" on page 16).

To Call:

Page 15

1.

2.

Select the channel that you and your group agreed to use for Selective Calling.

Press and hold the Tone Call Button for about 1.5 seconds. One long beep will be heard and the CAL indicator will appear on the LCD display while the

SELCALL ID is being transmitted automatically.

An Acknowledge Tone coming from the called radio will be received if you had successfully made contact.

The Acknowledge Tone for the SUNDOWNER UH-099 is a succession of three

Low Tone Beeps.

Other SELCALL Parameters

Aside from the Transmitter and Receiver lDs, you should also be familiar with some of the other SELCALL Parameters. This section outlines the following programming modes.

- Tune Period

- Lead-in Delay

- Lead-in Tone

- Alarm

RX SelcalllD, Tone Period, Lead-in Delay, Lead-in Tone, and Alarm Programming are mentioned separately from the TX SELCALL Programming because they are not frequently changed. Special procedures have been designed to prevent accidental programming.

Page 21

Tone Period

Tone Period is the duration of one tone in a SELCALL ID sequence. The setting of this parameter depends on the type of application.

On long distance communications for example, where the signal strength of the transmitted information is greatly reduced and affected by noise, it is advisable to use a longer Tone Period. A long Tone Period gives the decoder more time and information to check and evaluate the code.

However, be sure that all radios in your group use the same tone period setting.

Otherwise you will not be able to selectively call one another.

The Sundowner UH-099 allows you to select which tone period is best for you. The four most commonly used tone settings (20, 40, 70, or 100 mSec) are available. With the freedom to change this parameter, you can easily adapt to the existing system in your group without the inconvenience of having the unit serviced by the dealer.

Lead-in

Delay

Lead-in Delay is a SELCALL transmission parameter that "wakes-up" and helps the receiver of the other radio to lock onto the incoming signal. Each time a SELCALL ID is transmitted, the Lead-in Delay attaches itself to the beginning of the code sequence and cause the transmitter to be on for a longer period prior to the code transmission.

This makes for a stronger communication link between the transmitter and the other receiver.

One major advantage to having the longer Lead-in Delay is when selectively calling another radio via a repeater station. A long Lead-in Delay helps to stabilize both the communication link from your radio to the repeater station and from the repeater station to the other radio.

Lead-in Tone

The Lead-in Tone, when programmed, "rides" on the Lead-in Delay. Hence, when transmitting a SELCALL ID, a continuous tone will be heard for the duration of the

Lead-in Delay.

The main purpose of the Lead-in Tone is to increase the probability of contact between your unit and another radio

when

TSQ Scanning.

Normally during TSQ Scanning, if a carrier is detected and the unit does not notice

SELCALL information on its first "glance" of the particular signal, scanning resumes.

But if a Lead-in Tone is present, the unit continues to wait until the SELCALL ID is received.

2. Emits CALL Alarm for 10 seconds only.

3. Resumes Quiet condition automatically after 20 seconds if the call is not answered.

4. The unit will start decoding again when the 20 second period elapsed and the call remained unanswered.

Call Alarm Continue Mode

1. The unit will transmit an Acknowledge Tone to the Caller.

2. Initially emits an alarm of four successive beeps for 20 seconds and then two successive beeps every four seconds continuously unless answered.

3. Never resumes the Quiet Condition.

4. Continues to check if incoming codes have your Receiver SelcalllD even though the Quiet Condition is already opened. When detected, it will send an Acknowledge

Tone to the caller and then resets the Call Alarm.

Care and Maintenance

Notice

If the UH-099 has been subjected to extreme high .temperature

(above 60°C) for a prolonged period of time, blackening of the Liquid Crystal Display (LCD) may occur.

This is not a fault. Normal LCD operation resumes when the temperature stabilises back to proper operating conditions (0 to 55°C).

Preventive Maintenance

The following system checks should be made every six to twelve months:

1.

Check the Standing Wave Ratio (SWR).

2.

Inspect the tightness of all electrical connections.

3.

Inspect the antenna coaxial cable for wear or breaks on the shielding.

4.

Inspect the tightness of all screws and other mounting hardware.

Troubleshooting

Should the unit malfunction or perform poorly, follow the procedures indicated below:

1.

2.

3.

If the transceiver is completely inoperative ...

*

Check the power cord and fuse.

If there is trouble with receiving

...

*

Check the VOLUME control setting.

*

Be sure the SQUELCH is adjusted properly. Possibly the radio is oversquelched.

* Check that the radio is in an operational mode.

If there is trouble with transmitting

...

*

Check that the transmission line (coaxial cable) is securely connected to the

ANTENNA connector.

*

Check that the antenna is fully extended for proper operation.

*

Check that all transmission line (coaxial cable) connections are secure and free of corrosion.

Memory Backup

A built-in capacitor protects the channels stored in the SUNDOWNER UH-099 memory for up to 2 weeks after the DC power cable is disconnected.
