  • Page 10: Installation Of Accessories

    NSTALLATION OF CCESSORIES NTENNA NSTALLATION The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced reception on certain non-Amateur frequencies, you may wish to connect an antenna designed specifically for that frequency range, as the supplied antenna is necessarily a compromise outside the Amateur band, and cannot be expected to provide high performance at all frequencies.

  • Page 11: Battery Charging

    NSTALLATION OF CCESSORIES ATTERY HARGING If the battery has never been used, or its charge is depleted, it may be charged by connect- ing the NC-88 Overnight Battery Charger, as shown in the illustration, to the EXT DC jack. If only 12 ~ 16 Volt DC power is available, the optional E-DC-5B DC Cable (with its cigarette lighter plug) or E-DC-6 DC Cable (plug and wire only) may also be used for charging the battery.

    NSTALLATION OF CCESSORIES NSTALLATION Connect the hanger to the rear of the VX-170, with the notch pointing directly up, using the supplied screw (Figure 1). Use only the screw included with the clip to mount the clip to the back of the VX-170. Clip the Quick-Draw Belt Clip onto your belt (Figure 2).

  • Page 13: Interface Of Packet Tncs

    The VX-170 may be used for Packet operation, using the optional CT-91 Microphone Adapter (available from your Yaesu dealer) for easy interconnection to commonly-avail- able connectors wired to your TNC. You may also build your own cable, using a four- conductor miniature phone plug, per the diagram below.

To return to the VFO mode, press the [ VFO ( PRI )] key. When the radio is already set to the Memory mode, an easy way to recall memories is to key in the memory channel number, then press the [ F ] key.

  • Page 33: Labeling Memories

    EMORY ABELING EMORIES You may wish to append an alpha-numeric “Tag” (label) to a memory or memories, to aid in recollection of the channel’s use (such as a club name, etc.). This is easily accomplished using the Set Mode. 1. Recall the memory channel on which you wish to append a label. 2.

  • Page 35: Memory Bank Operation

    EMORY EMORY PERATION The large number of memories available in the VX-170 could be difficult to utilize without some means of organizing them. Fortunately, the VX-170 includes provision for dividing the memories into as many as ten Memory Groups, so you can categorize the memories in a manner convenient to you.

  • Page 52: Arts (Automatic Range Transponder System)

    ARTS™ UTOMATIC ANGE RANSPONDER YSTEM The ARTS™ feature uses DCS signaling to inform both parties when you and another ARTS™-equipped station are within communications range. This may be particularly use- ful during Search-and Rescue situations, where is important to stay in contact with other members of your group.
  • Page 53 ARTS™ UTOMATIC ANGE RANSPONDER YSTEM 4. Press the [ F ] key momentarily to exit ARTS™ operation and resume normal function- ing of the transceiver. ARTS™ constitutes a form of “remote control” operation that may be re- stricted to certain frequencies. U.S. users should confirm the current status of §97.201(b) of the FCC’s rules governing the 144 MHz band of the Ama- teur service before utilizing this feature.

    ISCELLANEOUS ETTINGS ASSWORD The VX-170 provides a security password feature which can minimize the chance that your transceiver could be used by an unauthorized party. When the password feature is activated, the radio will ask for the four digit password to be entered when the radio is first turned on.

  • Page 61: Programming The Key Assignment

    ISCELLANEOUS ETTINGS ASSWORD If you forget the password number, you may turn on the transceiver by per- forming the “All Reset” procedure (see page 65). However, the VX-170 will clear the password, as well as all memories, and will restore all other settings to factory defaults.

  • Page 64: Transmitter Time-Out Timer (Tot)

    ISCELLANEOUS ETTINGS ( TOT ) RANSMITTER IMER The TOT feature provides a safety switch which limits transmission time to a pre-pro- grammed value. This will promote battery conservation by not allowing you to make ex- cessively-long transmissions, and in the event of a stuck PTT switch (perhaps if the radio or a Speaker/Mic is wedged between car seats) it can prevent interference to other users as well as battery depletion.
