The Filters can be installed in any order into
any of the three Filter Slots F1 through F3.
To install new filters:
1.
Remove the 4 cover screws, 2 on each
side of the Eagle.
2.
Carefully raise the top cover.
3.
If necessary, unplug speaker cable located
on the left side of the main board.
4.
Set the top cover aside
5.
Locate the Filter Cover Plate, it is
identified with F1, F2, F3 as seen below.
It has two screws holding it down.
6.
Remove the two screws holding the Filter
Cover Plate in place.
7.
You now see the standard 2.4KHz Filter
installed in Filter Slot 1 (F1), and two
more filter slots.
8.
Locate the location to insert the specific
filter into. Refer to Figure 2.10-2. This is
according to the Filter Cover, and not the
circuit board text. The order is shown on
the Filter Cover as F1, F2, F3 going from
back of the rig towards the front of the
rig.
The
ground
pins
are
easily
distinguished by the way the pins and
outer case connect together. The ground
pins will be inserted into the holes for that
filter closer to the front of the rig. The text
on the top of the filter will then read
properly from the rear of the radio. If your
filter comes with the vibration barrier
attached to the bottom just temporarily
remove this cover to verify polarity
direction to identify the ground location
and re-install vibration barrier.
9.
Reinstall Filter Cover with the two screws
just removed.

If you disconnected the speaker in step 3,
then reconnect it now.

screws from step 1.

Menu on how program the Eagle
