[. . . ] When you hear a “high tone” beep followed by a “low tone” beep, the DTMF Pager is now disabled. CTCSS/DCS Bell Operation When this feature is activated, the Bell will ring when a station calls you whose transceiver is sending a CTCSS tone or DCS code which matches that set into your Decoder. To enable or disable the CTCSS/DCS Bell Operation, press and hold in the [B] key for two seconds; When you hear a“low tone” beep followed by a “high tone” beep, CTCSS/DCS Bell Operation is now activated. When you hear a “high tone” beep followed by a “low tone” beep, CTCSS/DCS Bell Operation is now disabled. [. . . ] This function may be useful if you wish to change the order in which the frequencies are selected by the CH knob. Rotate the CH knob to select the channel on which you wish change the operating frequency. CTCSS Operation “CTCSS” is a selective calling system which uses a continuous, very-low-frequency tone that is filtered out so as not to be heard. If many stations are using the same channel frequency, CTCSS will keep your radio’s receiver squelched until a CTCSS tone is received matching the CTCSS tone you have selected for your radio. If CTCSS is turned off, any signal received can open your radio’s squelch. Rotate the CH knob to select a channel on which you wish change the CTCSS configuration. Press the [C] key, then enter the two-digit CTCSS Tone number from the keypad. DCS and ARTS* Operation “DCS” is similar in use to CTCSS, except DCS uses digital codes for more reliable operation. €ARTS” is a transponder feature, available when DCS is engaged, which will alert two ARTS-equipped radios when an “Out of Range” condition exists. The stations can then move to a better location to re-establish communications. Rotate the CH knob to select a channel on which you wish change the DCS configuration. To quiet the radio again, press and hold in the MONI button for one second. When your communication session is finished, switch off the radio by rotating the VOL control to the fully counter-clockwise position (into the click-stop). Note: The VX-246 can be programmed for DTMF Paging operation (this requires the optional FVP-25 Encryption/DTMF Pager Unit), and also for CTCSS and DCS operation. Refer to the “Changing the Channel Data” section for details. ADVANCED OPERATION DTMF Pager ON/OFF (requires optional FVP-25 Encryption/DTMF Pager Unit) DTMF Pager operation allows paging and selective calling, using a user-programmed DTMF tone sequence. When your radio is paged by a station bearing a tone sequence which matches yours, your radio’s squelch will open. To enable or disable the DTMF Pager, press and hold in the [A] key for two seconds; When you hear a “low tone” beep followed by a “high tone” beep, the DTMF Pager is now activated. When you hear a “high tone” beep followed by a “low tone” beep, the DTMF Pager is now disabled. CTCSS/DCS Bell Operation When this feature is activated, the Bell will ring when a station calls you whose transceiver is sending a CTCSS tone or DCS code which matches that set into your Decoder. To enable or disable the CTCSS/DCS Bell Operation, press and hold in the [B] key for two seconds; When you hear a“low tone” beep followed by a “high tone” beep, CTCSS/DCS Bell Operation is now activated. When you hear a “high tone” beep followed by a “low tone” beep, CTCSS/DCS Bell Operation is now disabled. [. . . ] € To remove the battery, turn the radio off and remove any protective cases. Open the Battery Pack Latch on the bottom of the radio, then slide the battery downward and out from the radio while tilting the Belt Clip upward slightly. Battery Charging Install the FNB-64 Ni-Cd battery pack onto the transceiver. Insert the transceiver into the NC-76; the antenna jack should be at the left side when viewing the charger from the front. [. . . ]
