Q. When I am receiving a transmission, the display shows that I am receiving a signal but cannot hear anything?

A. Check the volume control, if you still can’t hear the transmission, check to see if you have either the CTCSS or DCS code set on that channel, if either code has been enabled you will only hear transmissions that have the same code set. If you turn off any CTCSS or DCS codes you will be able to hear all transmissions on that channel?

Q. When I am transmitting; the other person cannot hear me?
A. Check that you are both on the same channel and both have the same CTCSS or DCS codes set.
B. Check that the antenna is securely connected to the ANTENNA connector.
C. Check that all connections are secure and free of corrosion.

Q. What is CTCSS?

A. CTCSS, or Continuous Tone Coded Squelching System, is an option that allows your UHF radio(s) to only pick up radio signals preceded by a “code”. This option helps to cut down on unwanted radio chatter. This is also known as PL, Private Line, Channel Guard, etc.

Q. If the UHF Radio dose not switch on at all?

A. Check the power lead (wire harness) and fuse.

Q. What is the range of the UHF radio?

A. The type of antenna you use and where it is mounted on your vehicle will affect the range. A Low gain antenna will give you less range but wider coverage. A high gain antenna will give you greater range but it produces a narrower field which is more directional. Mounting the antenna low on the vehicle will shield the transmission in the directions close to the vehicle, so ideally the antenna needs to be mounted as high as possible.

Q. How far does a UHF radio transmit?

A. Many factors affect how far an UHF radio will transmit including power of the radio and the environment in which it’s used (e.g. buildings, mountainous and surrounding vegetation can cause range problems).

Q. What is a Repeater?

A. A Repeater is a Radio Relay Station. It is used when the radio signal needs to be magnified to get the desired distance coverage. It works by receiving a radio signal from one unit, magnifying it and retransmitting the signal to another radio unit. It would be used in an area where coverage was hindered by terrain, buildings or other environmental conditions.

Q. Where are the repeater stations located?

A. There is a list of repeater stations across Australia. This list and the operational status of the repeaters can change so please check with the ACMA for the latest information on repeaters.

Q. I can’t save the frequency that I have selected for one of the 200RX only channels? Or I can’t programme any of the 200RX only channels?

A. 200RX only channel programming
4 sub bands, selected using
F then on/off to select 200rx
PR/LO ( 40100 00) displayed this is range 400 to 512MHz push and hold PRI/LO to change frequency or push PRI/LO again to enter sub band selection
PRI/LO will select memory 00 Frequency range 400MHz to 420MHz
PRI/LO will select memory 50 Frequency range 420MHz to 450MHz
PRI/LO will select memory 100 Frequency range 450MHz to 470MHz
PRI/LO will select memory 150 Frequency range 470MHz to 512MHz
PRI/LO will select memory 00 Frequency range 400MHz to 512MHz
To change frequency push and hold PRI/LO for 2 seconds “4xx00” will flash rotate channel knob to select desired frequency push PTI/LO again to select “400xx”
When finished push ID/CAL to save in selected memory location
If SC/MEM is pushed when in programming mode a channel scan will be started, the start frequency will be the bottom limit of the selected ban, when an active channel is found scanning will stop, the frequency can be saved by pressing the ID/CAL button, or to move to the next frequency push CH then rotate CH clockwise to keep going up in frequency or counter clockwise to go down in frequency.

Q. I am transmitting on my radio and the other party can’t hear me?

A. If you are using channels 1 to 8 or 41 to 48 you could be transmitting in Duplex mode, turn DPX off or move to another channel

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.
