Open the packing carton carefully, and save the
box and packing material f o r po ssible u se at a later
date . Inspect the FTV- 9 01R for any sign s o f

contact the shipping co mpany immediately, and
docu ment the da mage thoroughly .
The FTV- 901 R ha s been de signed for u se in many
area s o f the
world, u sing variou s AC supply
voltage s. There fore, be fore connecting t he FTV-
9 01 R to the AC outlet, be ab solutely certain that
the po wer specification on the rear o f the trans­
verter matche s your local supply voltage . OUR

The tran sverter may be situated in any po sition
without loss o f per for mance. The only constraint s
regarding installation involve air circulation : the
tr an sverter should be located where there is free
passage o f air around the cabinet and heat sink s.
The tran sverter should be connected to a good
earth ground .

should be maintained bet ween the V HF and HF
anter;mas . In all in stallation s, the antenna should be
clear of surrounding object s, if the de sire d p attern
is to be obtained .
Do not economize on coaxial cable, a s some
"bargain" cable s have very poor shield coverage,
and thi s may degrade per formance signific antly.
For the 4 3 0 MHz antenna, plea se u se a type N

runs we recommend type R G 8A
