Connecting the Microphone MIC Jack Push the MIC plug at the end of the microphone into the MIC jack until the connection locks into place. Gently tug the MIC cord to test that the connection is locked. Use the rubber cover which is on the MIC cord to seal the MIC jack entry from dust. Disconnecting the MIC from the MIC Jack Pull back the rubber cover and move it down along the cord.
Mounting the MIC Hanger The Microphone Hanger comes in two parts. How and where you mount the MIC hanger will determine which parts to use. Conventional Mounting with Screws Use the front part of the MIC Hanger only. Locate a suitable mounting position and mark and drill two 3mm holes. Fix the MIC Hanger into place with screws. Conventional Mounting with Double Sided Tape (not supplied) High quality Double-Sided tape can be found at good retail stores.
Operation Turning on the Power Press and hold the Power/Channel Selector. Low-Voltage/High-Voltage Alert If the power supply voltage exceeds 18VDC, an alert tone sounds and dc HI flashes for 5 seconds. The power source must not exceed 25VDC otherwise permanent damage may occur to your radio, which may not be covered by the manufacturer’s warranty. NOTE If the input voltage falls below 10VDC, dc Lo flashes for 5 seconds. The power turns off automatically if voltage falls below 8.5VDC.
Operation oF(off) - squelch open. 1 - max sensitivity (min squelch) 5 - med sensitivity (med squelch) 9 - min sensitivity (max/tight squelch) NOTE You must select a channel which is not in use before setting the SQUELCH control. (see p.12 for “Selecting a Channel”). Think of the squelch control as a gate. If you increase the squelch level to maximum it raises the ‘Squelch gate’ so only the strongest signals get through.
Operation Monitor Press and hold to open the squelch and receive all weak signals. Press and hold again to cancel. Selecting a Channel Turn the Channel Selector to select the desired channel. NOTE For your reference a list of the available channels, corresponding frequencies and guidelines for their use and selection is printed on page 23. For Australia, Channels 05 UH7700 Seriesfor Standard Microphone and 35 areNB reserved Emergency Calls.
Operation Recalling the Instant Channel Momentarily press [INST] on the microphone at any time to return to the Instant Channel. Press [INST] again to return to the previous channel. Transmitting The UHF CB Radio uses UHF-CB Channels. NOTE For your reference a list of the available channels, corresponding frequencies and guidelines for their use and selection is printed on page 23. For Australia, Channels 05 and 35 are reserved for Emergency Calls. Select the desired channel.
Operation Standard Operation without the aid of a Repeater station. Operation with the aid of a Repeater Repeater Station (Duplex). The signal coming from your radio is received by the Repeater Station and the re-transmitted at the same time on another channel. This operation is called “Duplexing”. For example, CH01 on Duplex Mode will Receive on CH01 but Transmit on CH31 CH02 on Duplex Mode will Receive on CH02 but Transmit on CH32 etc...
Operation Operating the UHF CB Radio in Duplex Mode For this example we are adopting CH01 as the channel being used in your area for repeater use. 2 times. The duplex setting flashes. 1. Press / to change the setting 2. Turn the Channel Selector or press between simplex and duplex (“ r ” for repeater channels 01 - 08 or “ n “ for repeater channels 41 - 48). 3. Press to store the setting. to save & exit the menu mode. Only channels 4. Press and hold 01 - 08 and 41 - 48 are available for Duplex.
Operation 2. To deactivate SCAN, press . Open Scan (OS) Mode 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 3 seconds for the signal to return, otherwise scanning resumes. After transmission in scan mode, the unit will wait 20 seconds for the signal to return, otherwise scanning resumes. To skip the active channel, turn the Channel Selector.
Operation If the Priority Channel becomes active the radio will stay on that channel for as long as the signal is present. If the received signal ceases, Priority Scanning continues after 3 seconds. If scanning stops on a channel which is not a Priority Channel, the radio will continue monitoring the Priority Channel for activity while listening to the active one. To deactivate SCAN, press the button. Add/Remove Channels from SCAN Memory Select which Scanning Mode you wish to use; OS or GS.
Operation Busy Channel Lockout If the channel is already in use, you can prevent the UHF CB Radio from transmitting . This is particularly important when using CTCSS/DCS. 1. Press 4 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.
