Battery capacity may be reduced during extremely cold weather operation. Keeping the

AC Operation Using NC-86B/C (Receiving only)
The VX-8R may be operated from your house current by use of the supplied NC-86B/C
Battery Charger. The NC-86B/C should only be used for reception, because it is not capable
of supplying sufficient current to support transmission.
To use the NC-86B/C, turn the transceiver off, then plug the miniature connector of the
Battery Charger into the EXT DC jack on the side of the radio. Now plug the Battery Charger
into the wall outlet. You may now turn on the transceiver.
Interface of Packet TNC
The VX-8R may be used for Packet operation, using the optional CT-131 microphone
adapter (availablefrom your Yaesu dealer) for easy interconnection to commonly-available
connectors wired to your TNC. You may also build your own cable using a four-conductor
miniature phone plug, per the diagram below.
The audio level from the receiver to the TNC may be adjusted by using the VOLUME knob,
as with voice operation. The input level to the VX-8R from the TNC should be adjusted at the
TNC side; the optimum input voltage is approximately 5 mV at 2000 Ohms.
Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent
voltage spikes from possibly damaging your transceiver.
