VX-6R OPERATING MANUAL60EPCS (ENHANCED PAGING & CODE SQUELCH)The VX-6R includes an Enhanced CTCSS tone encoder/decoder and a dedicated micro-processor providing paging and selective calling feature. This allows you to place a call toa specific station (Paging), and to receive calls of your choice directed only to you (CodeSquelch).The paging and code squelch systems use two pairs of (alternately switched) CTCSS toneswhich are stored in the pager memories. Basically, your receiver remains silent until itreceives the CTCSS tone pair that matches those stored in the Receiving Pager Memory.The squelch then opens so the caller is heard, and the paging ringer immediately sounds, ifactivated. When you close the PTT switch to transmit, the CTCSS tone pair which isstored in the Transmitting Pager Memory will be transmitted automatically.On the paged radio, the squelch will close automatically after the incoming page ends.Meanwhile, on the paging radio, the Enhanced Paging and Code Squelch system will bedisabled after the PTT switch is released after the paging transmission. You may re-acti-vate the Enhanced Paging and Code Squelch system again using Set Mode Item 43: PAGER,if desired.Storing the CTCSS Tone Pairs for EPCS Operation1. Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.2. Rotate the DIAL knob to select Set Mode Item 45: PAG.CDRfor the Receiving CTCSS Tone Pair or Set Mode Item 46:PAG.CDT for the Transmitting CTCSS Tone Pair.3. Press the [0(SET)] key momentarily to enable adjustment of thisSet Mode Item.4. Rotate the DIAL knob to set the CTCSS Tone number whichcorresponds to the first tone of the CTCSS Tone Pair.5. Press the [MODE(SP S)SQ TYP] key, then rotate the DIALknob to set the CTCSS Tone number which corresponds to thesecond tone of the CTCSS Tone Pair.6. Press the PTT switch to save the new setting and exit to normaloperation.T h e V X - 6 Rdoes not recog-nize the order ofthe 1st tone and the 2ndtone. In other words, forexample, the VX-6R con-siders both CTCSS pairs“10, 35” and “35, 10” tobe identical.Hz67.069.371.974.477.079.782.585.488.591.5No.01020304050607080910Hz94.897.4100.0103.5107.2110.9114.8118.8123.0127.3No.11121314151617181920Hz131.8136.5141.3146.2151.4156.7159.8162.2165.5167.9No.21222324252627282930Hz171.3173.8177.3179.9183.5186.2189.9192.8196.6199.5No.31323334353637383940Hz203.5206.5210.7218.1225.7229.1233.6241.8250.3254.1No.41424344454647484950CTCSS TONE NUMBER
