Introduction The Uniden UH-1 00 UHF two way radio is designed to provide you with years of trouble free service. Its rugged components and materials are capable of withstanding harsh environments. The unit may be mounted in several convenient locations using the universal mounting bracket. You can be confident in your choice of radio equipment because the UH-100 offers built-in SELCALL, Wide Liquid Crystal Display, Back-lit Control buttons, complete coverage of the UHF CB Frequency Band, and much more.

Operation Setting the Squelch 1. To turn the unit ON, rotate VOLUME clockwise. Adjust volume to a comfortable level. Note: You must select a channel which is not in use before setting the SQUELCH control on your radio. 2. Think of the Squelch control as a gate. If you turn SQUELCH fully clockwise it raises the "Squelch Gate" so high that no signals get through. ~~i ~IY Strong Signals Medium Signals ~ Weak Signals Noise 3.
4. To set the "Squelch Gate" to the desired level, turn SQUELCH counterclockwise until you hear noise. Then turn the SQUELCH clockwise just until the noise stops. Now only strong signals get through. .. .. Strong Signals . Medium Signals ~ Weak Signals Noise ~I Selecting a Channel 1.

Operation with the aid of a repeater 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-100 is designed withthe capability to access and use repeater stations. Channels 01 through 08 have the option to operate in Duplex Mode.

Scanning The UH-100 has a scanning feature that allows you to search for active channels automatically. Furthermore, the UH-100 is designed to have two types of scanning; Open Scanning (OS) and Group Scanning (GS), to give you flexibility and allow you to use the radio more effectively.

Voice Scrambler UH-100 has a built-in scrambler / de-scrambler circuit. The Voice Scrambler feature prevents users, without the necessary descrambler equipment, "understanding" your conversation. This feature is NOT operable on CH01 through CH08, CH31 through CH38, and CH11, and will only work between units with the voice scrambler feature compatible with the Uniden UH-100. To activate the audio scrambler, select an available channel for audio scrambling. egoCH10 Press SCRAMBLE, the' icon appears.

Selective Calling When you listen to UHF CB you will hear all the conversations going on, which can become annoying at times. Ideally you need a system that alerts you when the signal is from someone you wish to communicate with. You want your radio to be SELECTIVE about the people you talk to! That's what the Uniden UH-100 offers, with SELECTIVE CALLING, commonly known as SELCALL. It lets you know that the people you want to talk to are calling. To achieve this each radio must have a SELCALL ID.
This is UH-100 Calling..... The UH-1 00 is shipped from the factory with a SELCALL ID setting of "00000". Refer to the Advance Section on page 32 for details on how to change/customize your UH-100 SelcalllD. Making a Call To make a call, press and release the TONE CALL switch on the microphone.

Group Calling Most Selcall users will have several members in their group. It is possible that everyone in the group needs to be alerted at the same time, for example when an emergency situation occurs. Calling them one by one can be inconvenient and time consuming. It is possible to create a special code that will be recognized by every radio in the group when transmitted. Your UH-100 incorporates this feature known as Group Calling.
Tone squelch (Receiver Quieting) Receiver Quieting, or Tone Squelch (TSQ), is actually SELCALL in action. The UH100 receiver is muted and you cannot hear any signals until the mute is disengaged by reception of your Selcall code. Refer to page 8 for explanation of how the squelch system works. The Squelch discussed previously "screens" the received signal level, however in tone squelch mode, the squelch monitors the signal for your ID. 1. The Tone Squelch Control acts as an electronic lock.

Tone Squelch Scanning You may wish to limit your scanning activities so the UH-100 will only scan the channels you have pre-arranged to use with your SELCALL family.

SELCALL Advance Programming The Sundowner UH-1 00 radio is fully user programmable. It gives you the freedom to select your own radio ID, configure the radio's response when a call is received, change SELCALL parameters for compatibility with other UHF Radio brands, plus much more. Please read the following procedure carefully to understand the full SELCALL capability of this radio. This will enable you to utilize the SELCALL to maximum effect.
The illustration below outlines the user programmable Once inside the programming parameter menu. mode, use the .& or T to scroll on the menu. Press MEM to select. Change the setting using the .& or T key. Press MEM again to store and exit.
Radio ID Programming To program your own Radio ID, perform the following procedure. From the main menu, using the... or T key, go to the Radio ID Programming Menu. (If you have never changed this parameter, the Radio ID 00000 will be displayed) . C-JI 1IQ Press the MEM key to start programing. The last digit of the Radio ID will flash. This indicates that you can now enter your new Radio ID. The flashing digit is the one you can change. To select another digit, use the ~ or ~ to move position.
Tone Period Programming Tone Period is the duration of one tone in a SElCALL ID sequence. The setting of this parameter depends on the application. On long distance communications, 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.
Lead -In Delay Programming 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 causes 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.
To change, use the or 4000 mSec. or T key. You can select either 500,1000,2000,3000 When completed, press the MEM key. The new Lead - In Delay stops flashing and is stored in the radio memory. To return to normal operation, press and hold the OS/GS key for about 1.5 seconds, or, press either the or T key to go to the next programmable parameter. rl rsa, ~i ~ . ~PIJ~ rsa " Dolt I';J- -...

Group Call Mode Programming There are two ways the Group Call Code is transmiitted. The Uniden UH-100 can be programmed to accept either format. Group 1 setting recognizes a group call transmitted with equal tone period. Le. Calling 100 radios, with a tone period setting of 40 mSec. Group 2 setting recognizes a group call transmitted with the first Group Call Tone period extended by 3 times the original tone period setting (this is also the default setting). ~ A~ 40mSec ---+I I+I -.
Caller ID Decoding The Sundowner UH-1 00 radio uses a total of 10 digits when making a Selective Call. The first five digit is the ID of the radio to be called and the last five digit is its own ID. Some radios in the market use only nine digit. If any member of your group is not using Uniden radio, a quick check of its operating guide will advise you the signalling format it is using. To change the Caller ID setting. From the main menu, using the... or ... key, go to the Caller ID Decoding Menu.
Service Should you find it desirable or necessary to service your UH-100, we suggest you contact the Uniden Dealer where your purchase was made. Your dealer will be able to assist you with complete service information. If you require service that is within the terms of your warranty you should present a copy of your receipt to your dealer to authenticate your claim.
Care and Maintenance Notice If the UH-100 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 stabilizes back to standard 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.
