110Communicating with a Specific Remote StationUsing the Tone Squelch FunctionTips• The squelch type can be set for each frequency band on both A-band (Main) and B-band (Sub).• The CTCSS and DCS squelch settings are also active during scanning. If scanning is performed withthe CTCSS and DCS squelch function activated, scanning stops only when a signal containing thespecified CTCSS tone or DCS code is received.• Pressing the Monitor switch allows signals that do not contain a tone or DCS code, and signals withdifferent tones or DCS codes to all be heard.• Pressing and holding the key for over one second to change the Set mode option allows youto use this function more conveniently.[SIGNALING] → [3 DCS INVERSION]: Allows you to receiving the DCS code of the inverted phase.[SIGNALING] → [10 SQL EXPANSION]: Allows specifying squelch types for transmit and receiverespectively.Display OperationOFF Deactivates transmit/ receive tone squelch function, etc.TONE Activates CTCSS transmit tones ([TN] appears).TONE SQL Activates the tone squelch receive function ([TSQ] appears).DCS Activates the digital code squelch ([DCS] appears).REV TONEActivates the reverse tone ([RTN] appears).Use to monitor communications based on the squelch control system in whicha tone signal is contained when communication is not performed and the tonesignal disappears when communication starts.PR FREQActivates the no-communication squelch function for radios ([PR] appears).You can specify no-communication signal tone frequencies within the range from300 Hz to 3000 Hz in steps of 100 Hz.PAGER ( see page116)Activates a new pager function ([PAG] appears).When communicating via transceivers with your friends, specify personal codes(each code is composed of two tones) so that you can call only specific stations.D CD* Sends a DCS code only for transmission ([DC] appears).TONE-DCS* Sends a tone signal when transmitting, and waits for a DCS code when receiving([T-D] appears).D CD-TONE SQL* Sends a DCS code when transmitting, and waits for a tone signal when receiving([D-T] appears).*: Press and hold the key for over one second, then set [SIGNALING] → [10 SQL EXPANSION] toON. The setting options for D CD, TONE-DCS and D CD TONE SQL are added to the [SIGNALING] → [11SQL TYPE] in Set mode. This allows specifying the squelch types for transmit and receive respectively.Setting the Tone FrequencyThe tone frequency can be selected from 50 frequencies (from 67.0 Hz to 254.1 Hz).1 Press and hold the key for over one second.The transceiver enters Set mode.2 Touch [SIGNALING].3 Rotate the dial, then touch [12 TONE SQL FREQ].
