Q. What radio install options do I have?
A. Radio stays ON when the ignition is switched OFF
Connect the radio’s negative (black) lead to the vehicle chassis, or directly to the batteries negative terminal. Connect the radio’s positive (red) lead via the 2 Amp fuse to the battery’s positive terminal. Alternatively, the positive lead could be connected at the fuse box at a point that has +13.8 Volts continuously available (preferably the battery side of the ignition switch) via the 2 Amp fuse.
Radio turns OFF with the ignition switch
Connect the radio’s negative (black) lead to the vehicle’s chassis, or directly to the batteries negative terminal. The radio’s positive (red) lead should connect to an accessory point in the vehicle’s fuse box via the 2 Amp fuse.
Q. Does the radio have any optional accessories I can purchase?
A. If required you may install an external (8 ohm, min 5w power) speaker fitted with a 3.5mm plug (not supplied). See accessories tab.
Q. How do I turn the power on/off?
A. Rotate the power switch in a clockwise direction to turn the unit ON, adjust the volume to a comfortable level. Rotate the Power Switch counter clockwise until it clicks to turn off the power.
Q. How do I select a channel?
A. Press the up or down keys to step upwards or step downwards one or more channels.
Q. What is the Scan function and how does it work?
A. The radio SCAN function has the ability allow channels to be scanned for activity. Channels can be scanned at a rate of 40 channels per 7 seconds. When a signal is found scanning will stop at that channel to allow the signal to be heard, then resume scanning when the channel is clear again.
Q. What is Instant Scan and how does it work?
A. During Priority Scan press SCAN button to start instant Scan. Only the 3 channels programmed in the instant channel buttons will be scanned.
Q. How do you store a priority channel?
A. To store a Priority Channel, Press and hold PRI button. The letters “PRI” will appear when the priority channel is set. The channel you selected as your Priority channel will then be automatically monitored during the Priority Scan. Note: You can only store one channel as your priority channel. Storing a new PRI channel will overwrite the existing selection. To store a Priority Channel. 1. Select the required channel. 2. Press and hold the PRI button until a beep is heard. The letters “PRI” appear when the priority channel is set.
Q. How do I factory reset the settings on the radio?
A. If the radio’s display locks up or stops functioning properly, you might need to reset your radio. Caution: This procedure clears all the information you have stored in your radio. Before resetting your radio, try turning it off and on again. If your radio is still not functioning correctly it may need to be reset to its default settings. While holding the Channel up button, Turn the radio on, only LCD backlight will be on for 1 to 2 seconds. The radio will then return to its original factory out condition.
Q. Is this radio suitable for use outside of Australia?
A. All Oricom products are approved for use in Australia and NZ only, and although they will still work in other countries, they may not meet that countries requirement’s for voltage, operating frequencies or power RF levels and if used may interfere with other services which could attract penalties from the local administration authorities.
Q. What factors should I take into account when purchasing an antenna?
A. When choosing an antenna, it is important to consider the terrain in which the antenna is to be used and match the best radiating pattern for the environment.
– A 3dBi antenna has a wide pattern, ideal for undulating terrain.
– 6-6.5dBi antennas are popular due to their performance over distance on flatter or slightly uneven terrain.
Q. What is the range of a UHF CB Radio?
A. The range of a UHF CB radio is usually determined as the combined line of sight of both stations. UHF radio signals travel in straight lines between the radios and anything in between will attenuate the signals and in some cases, stop them altogether.
Q. How does the environment affect the range of my UHF CB radio and antenna?
A. The range of your UHF CB radio is more of a question of what is between the stations.
The attenuation of the signal in free air is very low, as moisture is added the attenuation becomes greater (anyone with satellite TV would have seen rain fade). Trees and other types of vegetation also contain water so a signal through a plantation or forest of trees will also be attenuated to some degree if not completely lost.
Q. What role does elevation play in the range of a UHF CB Radio?
A. There is an easy answer to the range question and that is “elevation is your friend”. Elevation improves the line of sight to the horizon it is also good if you are on the road and trying to communicate with another station a few vehicles in front of you, it may not be possible to talk between two handhelds but once you put an antenna outside and higher than the roof of the car communications might be possible, just a little elevation can make a big difference.
The advertised gain of an antenna is not the antenna amplifying the signal but just collecting or sending the signal in a specific direction, just like focusing a torch light the bulb produces the same amount of light, but the lens focuses it in to a narrow beam of light. With this in mind if the antenna is too directional, then you may not hear stations that are not in the reception “window” of the antenna.
Most UHF CB antennas are vertical poles and send the signal out in a circular pattern around the antenna (like a donut shape with the antenna in the middle) if an antenna has more gain this donut is flattened between the top and bottom so more signal is concentrated in horizontal direction. This is great if the other station is directly in front at a 90° angle to the antenna then all the signals are collected from that station but if they are on top of a hill at 45° angle then they may not be in the reception “window” of the antenna and therefore the signal may be very weak.
