A total of 5 optional crystal IF filter units can be in-
stalled in addition to the factory-installed filters (see
the table). Contact your dealer for pricing, availability
and ordering. These filters include small boards with
connectors, so no soldering is necessary for their in-
stallation.
Important! After filter installation, front-panel se-
lection is not possible until individual filters are enabled
via menu programming ( menus selection 5-0 ~ 5-8 ). Re-
fer to the Menu Programming chapter and enable the
optional filters after installing them.
Filter Installation
r Disconnect all cables from the transceiver.
r Referring to Figure 1, remove the four screws (
on each side of the transceiver, and the seven
ž
screws (
) from the bottom of the transceiver, then
lift off the bottom cover.
r Referring to Figure 2, remove the six screws (
from the top panel. Pry the top cover open and dis-
connect the speaker cable from the speaker, then
lift off the top and side covers.
r On the underside of the transceiver chassis, locate
the IF UNIT. Referring to the drowing below, deter-
mine the location of the filter(s) you are installing.
r Position each filter so that its connectors are aligned
with the mounting pins on the board, and push it
into place, so the nylon mounting tabs "mushroom"
through the holes and lock the unit in place.
r Connect the speaker cable to the speaker on the
top cover, then replace the all covers and screws
(unless installing other options now). Refer to pages
101 and 102 of the Menu Programming chapter to
enable newly-installed filters.
