Vertex Standard VX-8R Manual Do Utilizador

The VX-8R may be used for Packet operation, using the optional CT-44 and CT-131
microphone adapter (available from your Yaesu dealer) for easy interconnection to com-
monly-available connectors wired to your TNC. You may also build your own cable using
a four-conductor miniature phone plug.

The audio level from the receiver to the TNC may be adjusted by rotating the DIAL knob
while pressing and holding the 

 key, 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, to prevent volt-
age spikes from damaging your transceiver.
