VX-127 OPERATING MANUAL26You also can press the MONI key during Tone Scanning to listen to the (muted) signalfrom the other station. When you release the MONI key, Tone Scanning will resume afterabout a second. Tone Scanning works either in the VFO or Memory modes.EPCS (ENHANCED PAGING & CODE SQUELCH)The VX-127 includes an Enhanced CTCSS tone encoder/decoder and a dedicated micropro-cessor providing paging and selective calling features. This allows you to place a call to aspecific station (Paging), and to receive calls of your choice directed only to you (Code Squelch).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.Storing the CTCSS Tone Pairs for EPCS Operation1.

Press the [(MHz)] or [(MHz)] key,then rotate the DIAL knob to set the CTCSSTone number whichcorresponds to the sec-ond tone of the CTCSSTone Pair.6. Press the PTT switch tosave the new settingand exit to normal op-eration.CTCSS/DCS/EPCS OPERATIONHz67.069.371.974.477.079.782.585.488.591.5No.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 NUMBERTONE SEARCH SCANNING |
