Inspection
Inspect the transceiver thoroughly immedi-
ately upon opening the packing carton. Confirm
that all controls and switches work freely, and
inspect the cabinet for any damage. Make sure
the accessory fuses and plugs pictured on page 3
are included. If any damage is found document
it completely, and contact the shipping company
(or dealer, if you purchased it over the counter)
right away. Save the packing materials in case
you need to return the set for service.
If you purchased optional internal accessories
separately, install them as described in
Installing
Internal Accessories (page
36). This chapter de-
scribes base station installation first, followed by
mobile installation and then interconnections
with external accessories.
AC Power Supply
The FT-890 is designed for operation from
13.5-V DC, negative ground. For base station
installations, we recommend the matching Yaesu
FP-800 AC power supply which was specifically
designed for this purpose, and which includes a
large loudspeaker for the transceiver and its own
cooling fan. You can use another DC source ca-
pable of providing 20 amperes at 13.5-V DC with
Caution!
Permanent damage can result if improper
supply voltage is applied t o the trans-
ceiver. Your warranty does not cover dam-
age caused by application of AC, reversed
polarity DC, or DC outside of the specified
range of 13.5 V+10%.
the supplied DC cable assembly, but you must be
extremely careful to avoid reversed polarity con-
nection. See the Caution box above.
If you are connecting the FP-800 with the FT-
890, before connecting power, check the label on
the rear of the FP-800 which indicates the AC
mains voltage range for which the supply is cur-
rently set. If your AC mains voltage is outside of
this range, the transformer taps inside the power
supply must be rewired, and the fuse in the
FP-800 must be changed. This involves some
soldering of the AC mains input (see below), so
you should ask your dealer for assistance if you
are not experienced with this sort of work.
Incor-
rect connections could cause serious damage not cov-
ered by the warranty.

If
you change the AC

not use a slow-blow
