Introduction
The Vertex Standard VX-800 is a compact, hand-held
portable transceiver for the VHF land mobile bands
that offers the convenience of small size, light
weight, and simple operation. The VX-800 can be
programmed by your Vertex Standard Dealer with
up to 200 channels for both single and split fre-
quency operation. The VX-800 provides up to 5 watts
of RF output power and includes a flexible quick-
connect antenna.
The transceiver and Ni-Cd, Li-Ion battery packs are
constructed of thick high impact polycarbonate plas-
tic, with special attention paid by the designers to
tight sealing and ruggedness, assuring years of reli-
able operation even in harsh environments.
The following pages describe the operation, features
and accessories of the VX-800. Following the dis-
cussion of transceiver operation, details regarding
programming software, alignment, and mainte-
nance will follow.
