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 PTT 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 MENU button (11)once, the current channel number flashes on the display.• Press the - button (4) or the - button (7) to change the channel.• Press the PTT - button to (15) confirm and return to stand-by Mode.Note:If no button is pressed within 15 seconds during setting, the unit will return to standby.6.CTCSS (Continious Tone Coded Squelch System)License free radio's operating on the 400~470 MHz frequency band, like the Twintalker , have 8/20/22 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 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)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.7.CTCSS• Press the MENU-button(11) twice : The current CTCSS code flashes on the display.• Press the -button(4) or the -button(7) to change to another code.• Press the PTT-button(15) to confirm and return to stand-by mode.Note:To disable CTCSS, select code "0F” for CTCSS in the menu.When the entry is confirmed, "OF" will be displayed.8.MonitorYou can use the monitor feature to check for weaker signals in the current channel.• Press the MON-button to activate channel monitoring.• Press the MON-button to stop channel monitoring.Note:During channel monitoring the receiver circuit in the Radio’s will not listen to CTCSS codes.
