12.7 Sub -channels : CTCSS (Continious Tone Coded Squelch System) /
DCS (Digital Coded Squelch)
License free PMR radio's operating on the 446 MHz frequency band, have 8 available radio channels. If there are many PMR users
in your neighborhood, there is a chance that some of these users are operating on the same radio channel.
To prevent that you receive signals from other users, sub-channels have been integrated.
Two PMR radio's will only be able to communicate with each other when they are operating on the same radio channel and when they
have selected exactly the same sub-channel.
There are two kind of sub-channels :
• Continuous Tone Coded Squelch System (CTCSS)
• Digital Coded Squelch (DCS)
When using CTCSS, a low frequency tone (between 67 and 250 Hz) will be transmitted along with the voice signal. There are 38
available tones to choose from. You are free to choose one of these 38 available tones. Due to filtering, these tones will generally not
be audible so they will not disturb the communication.
DCS is similar to CTCSS, but instead of sending a continuous tone of a selected frequency, a digital data transmission is added to the
radio signal. This Digital Code is transmitted at a really low rate, around 134 bits per second (the code is 23 bits long). Only the PMR's
of the latest generation will support DCS. There are 83 available DCS codes that can be used. Since earlier models will only support
CTCSS it will be better to use DCS to prevent that other users will be audible during your PMR conversations.
To turn ON:
• Press and hold the - key for 2 seconds. The unit will “beep” and the LCD
display will display the current channel.
To switch OFF:
• Press and hold the - key for 2 seconds. The unit will “beep” and the LCD
display will turn blank.
Do not short-circuit the batteries or dispose in fire. Remove the batteries if this device is not going to
be used for a long period.
Do not charge non rechargeable batteries like Alkaline batteries in the charger. This might damage the
PMR’s and charger unit.
If the segments and icons of the displays are shown in light grey in this user guide, it indicates
that they are blinking.

• Press and hold the PTT - key to transmit. The TX symbol is displayed.
• Hold the unit in a vertical position with the microphone 10cm from the mouth and
speak into the microphone .
• Release the PTT - key when you want to stop transmitting.
• Use the - key or the - key to go to a higher or lower
channel.
• Press the PTT - key to confirm
When the battery is almost empty, the unit will turn OFF automatically after 30 seconds.

In order for other people to receive your transmission, they must also be on the same channel and have
set the same sub-channel (Chapter 12.6 and 12.7).
