CTCSS/DCS Signalling             CTCSS/DCS may have been programmed on a channel to ignore unwanted calls from other parties on the same channel. When CTCSS/DCS signalling is set, the squelch will be opened only when signals containing the matching tone or code are received. This allows you to ignore (not hear) these calls. Likewise, your signals will be received only by parties using the same CTCSS/DCS signalling.             Although it may seem like you have a private channel while using CTCSS/DCS signalling, other parties can still hear your calls if they use the same tone or code.              DTMF Signalling             DTMF  Signalling is enabled/disabled by your dealer. When DTMF  signaling is programmed on a channel, press the programmable key (Call 1, Call 2) to transmit DTMF code.               ?LED glows red during transmission and goes out when transmission ends.  2-Tone/5-Tone/HDC2400TM  Signalling 2-Tone/5-Tone/HDC2400TM signalling is enabled/disabled by your dealer. When 2-Tone/ 5-Tone/HDC2400TM signalling is programmed on a channel, press the programmable key (Call 1, Call 2) to transmit 2-Tone/5-Tone/HDC2400TM signal. When 2-Tone/5-Tone/HDC2400TM is set on a channel, the preset functions will be
 27 activated only when the matching 2-Tone/5-Tone/HDC2400TM signals are received. Likewise, your signals will be received only by parties using the same 2-Tone/5-Tone/ HDC2400TM signals.   ●  The LED glows red during transmission; when the transmission is completed, the LED solidly glows orange until the preset time elapses. ●  The LED glows green  during decoding, and flashes orange until the preset time elapses to indicate successful decoding.    Signalling AND / OR Logic Signalling "AND"/"OR" sets the audio unmute condition for any channel programmed with CTCSS/DCS or Opt Signalling (2-Tone/5-Tone/HDC2400TM ). CTCSS/DCS AND 2-Tone/5-Tone/DTMF/HDC2400TM:                   The squelch opens only when both CTCSS/DCS and Opt Signalling (2-Tone/5-Tone/ DTMF/HDC2400TM) are received and matches the preset one on selected channel.   CTCSS/DCS OR 2-Tone/5-Tone/DTMF/HDC2400TM:    The squelch opens when either CTCSS/DCS or Opt Signalling (2-Tone/5-Tone/DTMF/ HDC2400TM) is received and matches the preset one on selected channel.  PTT ID PTT ID (BOT/EOT/Both) is used to access and release repeaters and telephone systems. BOT ID (Beginning of Transmission): The radio transmits the ID code (2-Tone/5-Tone/HDC2400TM) immediately after it begins transmission, when the [PTT] key is pressed.   EOT ID (End of Transmission):   The  radio transmits the ID code (2-Tone/5-Tone/HDC2400TM) just before it ends transmission, when the [PTT] key is released.   Both: The radio transmits the ID code when it begins/ ends transmission.
