    The FBA-39 is designed for use only with AA-type Alkaline cells. If you do not use the VX-8DR/DE for a long time, remove the Alkaline batteries from the FBA-39, as battery leakage could cause damage to the FBA-39 and/or the trans- ceiver.

  • Page 14: Interface Of Packet Tncs

    The input level to the VX-8DR/DE from the TNC should be adjusted at the TNC side; the optimum input volt- age 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.

  • Page 15: Operation

    Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the VX-8DR/DE. I know you’re anxious to get on the air, but I encourage you to read the “Operation” section of this manual as thoroughly as possible, so you’ll get the most out of this fantastic new transceiver.
