If using an external antenna for transmission, ensure that the SWR presented to
the transceiver is 1.5:1 or lower.
Installation of FNB-82LI Battery Pack
The FNB-80LI is a high-performance Lithium-Ion battery providing high capacity in a
very compact package. Under normal use, the FNB-82LI may be used for approximately
300 charge cycles, after which operating time may be expected to decrease. If you have
an old battery pack which is displaying capacity which has become diminished, you
should replace the pack with a new one.
Referring to Figure 1, slide the Battery Cover toward the bottom to remove it while
slide the Battery Cover Latch.
Referring to Figure 2, install the FNB-82LI into the Battery Nest.
Replace the Battery Cover, as shown in Figure 3.
If the battery has never been used, or its charge is depleted, it may be charged by
connecting the NC-85 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-21 DC Adapter (with its
cigarette lighter plug) may also be used for charging the battery.
While the battery is being charged, display will indicate "CHGING" and the TX/BUSY
indicator will glow red.
When charging is finished, display will change to indicate "CHGFUL" and the TX/BUSY
indicator will change to glow green.
The VX-2R may be used for Packet operation, using the optional CT-91 microphone
adapter (available from 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-2R 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.
