Yaesu VX-127 Operating Manual

VX-127 OPERATING MANUAL 57The VX-127 allows you to utilize a DTMF (Dual-Tone, Multi-Frequency) tone encoder/decoder, with a dedicated microprocessor providing paging and selective calling featuresnow that you've installed the optional FTD-7 DTMF Paging Unit. This capability allowsyou to make a call to a specific station (Paging), and to receive calls of your choice di-rected only to you (Code Squelch).The paging and code squelch systems use 3-digit numeric codes (000 - 999) which arestored in the DTMF Pager Memories. Basically, your receiver remains silent until it re-ceives the 3-digit DTMF pager code that matches those stored in the DTMF Pager Memory.The squelch then opens so the caller is heard, and the LCD displays the 3-digit DTMFpager code which was received. Also, the paging ringer immediately sounds, if the Bellfunction is activated. When you close the PTT switch to transmit, the 3-digit DTMF pagercode which is stored in the last selected DTMF Pager Memory register will be transmittedautomatically.On the paged radio, the squelch will close automatically five seconds after the incomingpage ends (you may now resume DTMF Pager operation).Storing the 3-digit code for the DTMF Pager Operation1. Press the [SET( )EMG] key momentarily to enter the Set mode.2. Rotate the DIAL knob to select Set Mode Item 56: PAG.COD.3. Press the [F] key momentarily to enable adjustment of this SetMode Item.4. Rotate the DIAL knob to select the DTMF Pager Memory regis-ter into which you wish to store the access code.5. Press the [F] key momentarily. The first digit will blink.6. Rotate the DIAL knob to select the first digit of the 3-digit DTMFpager code. The “A” and “D” keys are “wild cards.”7. Press the [F] key momentarily to accept the first digit and moveto the second digit of the 3-digit DTMF pager code.8. Repeat the previous steps until you have completed the 3-digitDTMF pager code.9. Press the [REV(HOME)] key to toggle the decoder “on” and“off.” When the decoder is set to “off,” the “- -” notation appearsbetween the DTMF pager memory register number and the 3-digit DTMF pager code; for example, “P2- -123.”The 3-digit DTMF pager code which does not have the “- -” notation is used for en-code only.10. Press the PTT switch to save the new settings and exit to normal operation.DTMF PAGER OPERATION (REQUIRES OPTIONAL FTD-7)
