Oricom UHF2100 manual Operation, Setting the CTCSS sub-channel

Operation

These are paired with higher channels as output/input (1/31, 2/32, etc.)

Check for local repeater activity before using these channels in Simplex mode to avoid interference. Channels 9 and above are the best choices for general use in Simplex mode.

You can find more information about channels and frequencies by visiting the Web site http://www.acma.gov.au/ACMAINTER.786700 :STANDARD:1627891715:pc=PC_1265#Repeaters

Note: Refer to the “Channel Table” section of this Owner’s Manual for detailed frequency listing.

Setting the CTCSS sub-channel

Each channel has 38 sub-channels to let you set up group of users within the same channel for more private communication. If you have set the sub-channel, you can only communicate with other radio users tuned to the same channel and sub-channel.

To turn the sub-channel function off, simply set the sub- channel to 0 (zero). You can then communicate with other radio’s setting to the same channel who also turns off the sub-channel operation (or whose unit does not have the sub-channel feature).

a. Press the MENU button twice, the current CTCSS sub- channel number flashes on the LCD screen.

b. Press the UP or DOWN button to select one of the 38 CTCSS sub-channels.

c. Press the PTT button to confirm the CTCSS sub-channel setting.
