Getting Started Connect Drop-In Charger with AC adaptor Plug one end of the AC adaptor into the wall outlet and the other end into the drop-in charger. OR... Connect Cigarette Lead Charger to Cigarette Lighter Jack NOTE • The drop-in charger and cigarette lead charger are not water proof. Ensure the radio is dry before connecting to the charger.
Getting Started Attaching the Battery Pack Contacts 1. Place the battery pack onto the back of the radio. It will only fit in one way. 2. Snap the battery release clip until it clicks. Be sure the battery pack fits tightly against the UH078SX-NB body. CAUTION Avoid exposing the Lithium Ion battery, attached or unattached to the radio, in direct sunshine, heated cars, or in areas with temperatures below –20°C (–4°F) or above +60°C (+140°F).
Getting Started 4. To take the beltclip off the radio, turn it and slid it up. Charging the Battery Pack Your radio is powered by a specially designed Lithium Ion battery pack. • Before operating the UH078SX-NB, charge the Lithium Ion battery pack for 5 hours without interruption in the drop-in charger or 3.5 hours without interruption in the cigarette lead charger. NOTE For the initial battery charge, make sure the radio is off for optimum charging.
Getting Started Battery Level Display The BATTERY icon in the top right hand corner of the screen indicates the UH078SX-NB current battery voltage level at all times. The battery level is displayed in 4 levels. LEVEL 4 Battery 100% full LEVEL 3 Battery approx. 40% capacity LEVEL 2 Low Battery LEVEL 1 (flashing) Empty Battery NOTE NOTE When PTT is pressed at Level Empty, battery icon and channel number will flash, transmission is disabled. Recharge the battery at any time.
Getting Started Battery Level Display (when charging) Radio OFF (normal charging) 5 hours without interruption in the drop-in charger or 3.5 hours without interruption in the cigarette lead charger. Radio ON (slow charging) Battery Level indication LEVEL 0 Transmit is inhibited at this level. Battery must charge up to Battery Level 1 before Transmit is enabled.
Getting Started Mount the Hang-Up Bracket Use the radio Hang-up Bracket when charging the uh078sx Deluxe with the Cigarette Lead Charger in a vehicle. The radio Hang-up Bracket comes in two parts. How and where you choose to mount the Hang-up Bracket will determine which parts to use. Conventional Mounting with Screws Use the front part of the Hang-up Bracket only. Locate a suitable mounting position in the vehicle and mark and drill two 3mm holes. Fix the Hang-up Bracket into place with screws.
Operation • See the Controls and Indicators page at the back of this operating guide for button and key operations. Power On/Off To turn the unit ON, rotate the [ON/OFF VOL] clockwise. A channel number and battery level should appear on the display. To turn the unit OFF, rotate the [ON/OFF VOL] knob counter-clockwise. The display will disappear. Volume Rotate the [ON/OFF VOL] knob clockwise or counter-clockwise to adjust speaker volume to desired listening level.
Operation Roger Beep Roger Beep is a BEEP that is sent to notify the end of transmission (both PTT and VOX transmission.) Roger Beep can be heard through the speaker when Key Beep is on. Roger Beep is transmitted even if key beep is turned off. However Roger Beep will not be heard from the speaker. 1. Press MENU six times. or 2. Press 3. Press and hold and current setting flashes. to change setting ON/OFF. MENU to store setting.
Operation Squelch The squelch is used to eliminate any annoying background noise when there areSQUELCH no signals present. The squelch is used to eliminate any annoying background noise when there are no signals present. NOTE Make sure to first select a channel not in use before setting the squelch intoyour UH078SX-NB UHF-CB radio. Make sure first select a channel not in use before setting the squelch in your UH076SX UHF-CB radio. of squelch as a gate.
Operation To Transmit and Receive The UH078SX-NB uses the UHF-CB Channels. For your reference a list of the available channels and corresponding frequencies is printed on p.28-p.29. NOTE UHF-CB Channels 22 and 23 are for telemetry and telecommand applications. Transmit is inhibited on these channels. 1. The maximum RF transmit power of UH078SX-NB is 5 Watts. Press TXP to change the transmit power between High(5W), Middle(1W) and Low(0.5W). HI appears when on high power. LO appears when on low power.
Operation 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.
Operation To Operate UH078SX-NB in Duplex Mode Eg. CH01 is being used in your area for repeater use. 1. Press MENU dP flashes. 2. Press or to change setting ON/OFF. r appears (for repeater channels 01 - 08) in place of 0 and n appears (for repeater channels 41 - 48) in place of 4 when duplex is on. 3. Press and hold NOTE MENU to store setting. Check with your local retailer for available repeaters. Scanning The UH078SX-NB has two types of scanning; Open Scanning (OS) and Group Scanning (GS).
Operation To skip the active channel, press mem momentarily. Scanning resumes. To deactivate SCAN, press scan or PTT . NOTE If SCAN is deactivated while in an active channel, the UH078SX-NB will stay on that active channel. If no other channels are active, the UH078SX-NB will reinstate the starting channel. Group Scan (GS) Mode Allows you to monitor a Priority Channel while scanning. To use GS Mode Scanning, press the the display. os/gs key.
Operation Programming Scan Channels 1. Select which Scanning Mode you wish to use OS or GS Mode. NOTE OS is indicated by the absence of the GS icon. 2. Select the channel you want to store by pressing 3. Press and hold mem or . . M appears and a short tone beep is heard. 4. To remove the channels from Memory, press and hold more. A short tone beep sounds and M disappears.
Operation 60 Receive Channels The UH078SX-NB also has 60 receive only channels (CH81 - CH140) which can be programmed with frequencies ranging from 450-512MHz (in 12.5kHz steps). If you know the frequency you may store it manually. Manual Programming Turn power off. Press and hold MENU while turning power back on. The channel indicator flashes the lowest available empty channel. You may use the or to select another channel. Press MENU . The frequency indicator flashes the MHz whole number value to be set.
Operation Advanced Features CTCSS (Continuous Tone Coded Squelch System) This feature allows you to receive signals only from callers who have selected the same CTCSS code. Press or to select the channel you want to set a CTCSS code. Press and hold ctcss . CTCSS will flash. or to select a desired CTCSS code. Press Press and hold MENU to store setting. When a code other than oF is selected, CTCSS and code will display. DCS (Digitally Coded Squelch) DCS is a digital extension of CTCSS.
Operation VOX • Built-in Voice Activated Circuit (VOX) feature enables the user to transmit automatically by speaking on the microphone of the VOX headset (not supplied) without pressing the PTT switch. NOTE VOX feature will not work without the VOX Headset Microphone. The built in mic of UH078SX-NB is temporarily disabled when VOX feature is working, however accidental pressing of PTT will cause the unit to transmit briefly. To activate VOX 1. Press MENU two times.

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 and DCS 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.
