USING THE TWINTALKER

1. Turning the device on/off: To turn the devices on or off, hold down the on/off button (6) for 3 seconds a BEEP sound will be played to confirm.
2. Adjusting the volume: To increase the volume, press the Up adjustor button ▲ (4) and press the Down ▼ (7) button to decrease volume.

   When the battery charge level is low, the battery icon will flash and a beep will be heard to indicate that the batteries need to be replaced or recharged.
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 thesame 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 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 TALK - 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 462 MHz frequency band, like the Twintalker, have 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 subchannels:
   • 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 TALK-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. Monitor
   You 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.
9. VOX Selection
   The Radio's is capable of voice activated (VOX) transmission. In VOX mode, the radio will transmit a signal when it is activated by your voice or other sound around you. VOX operation is not recommended if you plan to use your radio in a noisy or windy environment.
   Note: VOX mode will be overrided when you press the TALK - button "15".
   • Press the MENU- button (11) three times, the current VOX setting flashes on the display and the VOX icon is displayed.
   • Press ▲- button(4) to set the VOX sensitivity level between 1 and 3 (level 3 is the most sensitive level).
   • Press ▼- button(7) until "OF" appears on the display, to turn VOX OFF.
   • Press the TALK-button (15) to confirm and return to stand-by mode.
10. Scanning for an active radio channel
    • Press the SCAN -button (21): The 'Scan' function indicator (17) will appear on the screen and the channel (18) will scan continuously from 1 to 22.
    • Press the ▼- button (7) to start the channel scan from 22 to 1.
      Once an active channel is found, the scanning will stop and you can listen to the transmission.
      When the transmission on the found channel stops, the scanning will resume automatically.
      NOTE: If you press the TALK button (15) while listening to a found channel, the Radio's will go back in stand-by mode on the found channel.
