4. Receiving/transmitting communications:
The devices are in ‘Reception’ mode when lit up,i.e. they are ready to receive
a call or sound transmitted on the activated frequency.
·When you press the Call tone button(12),the device switches to ‘Transmission’
mode. You are then transmitting a sound signal to the other device.
·To send a voice message, press the TALK button(15) and speak into the microphone(10).
Continue to press the button until you have finished transmitting your message. Hold
the microphone a minimum of 5 cm from your face.
Note:
- The other device must be set to the same channel and have set the same CTCSS code
(see point 7)
- When the transmission is complete and the TALK button (15) is no longer held down,
the other device will emit a sound (BEEP) to indicate that this device is ready to
transmit.
5. Changing Channels

·Press the-▲ button(4) or the-▼ button(7) to change the channel.

6. CTCSS(Continuous Tone Codes Squelch System)
License free radios operating on the 462 MHz frequency band, like the Twintalker,
have 7 available radio channels. If there are many radio’s 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 radios 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 kinds of sub-channels:
·Continuous Tone Coded Squelch System(CTCSS)
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.
