Memory backup
The T-4555 uses a battery-less memory backup system
in order to retain radio presets and other settings when
it’s unplugged or in the case of a power failure.
Although no batteries are required, the T-4555 must be
plugged into an AC outlet in order to charge the backup
system.
Once it has been charged, the T-4555 will retain the set-
tings for several weeks, although this depends on the
environment and will be shorter in humid climates.

Connecting an Outdoor AM Antenna
If good reception cannot be achieved using the supplied
AM loop antenna, an outdoor AM antenna can be used
in addition to the loop antenna, as shown.
Outdoor antenna
Insulated antenna cable
AM loop antenna
Outdoor AM antennas work best when installed hori-
zontally outside, but good results can sometimes be
obtained indoors by mounting horizontally above a win-
dow. Note that the AM loop antenna should be left con-
nected.
Connecting an Outdoor FM Antenna
If you cannot achieve good reception with the supplied
indoor FM antenna, try a commercially available out-
door FM antenna instead.
Outdoor antenna must be grounded in accordance with
local regulations to prevent electrical shock hazards.
Notes:
• Outdoor FM antennas work best outside, but usable
results can sometimes be obtained when installed in
an attic or loft.
• For best results, install the outdoor FM antenna well
away from tall buildings, preferably with a clear line
of sight to your local FM transmitter.
• Outdoor antenna should be located away from possi-
ble noise sources, such as neon signs, busy roads, etc.

Optional Tuner Boards—Continued
Installing a Board
Insert the board between the guide rails
and push it in.

Use the Allen wrench, hexagonal socket head screws,
removal thumbscrews, and so on supplied with the
board.
Turn off the T-4555, and then unplug the
power cord from the wall outlet.
1
Use the supplied Allen wrench to unscrew
2
the two hexagonal socket head screws
that are securing the existing board or
blanking plate.
When the board meets the internal connector,
apply a little more pressure so that the board
plugs fully into the connector. Make sure the
board’s panel is flush with the T-4555’s rear
panel.
75
Use the Allen wrench to screw tight the
two hexagonal socket head screws so
that the board is secure.
6
Screw the supplied removal thumbscrews
3
into the two holes just below the holes
that were used by the hexagonal socket
head screws. Screw them in about 3/16"
(5 mm). Hold and pull both of the thumb-
screws to remove the board.
Be sure to fully tighten the screws. If they are
loose, the ground connection between the board
and the T-4555 may be inadequate, resulting in
noise or failure.

Caution:
If any of the screws use washers, be sure to reuse
them when installing or removing a board.
Carefully remove the board from its bag.

To prevent electrostatic
damage, hold the board by
its panel, taking care not
to touch any of the com-
ponents or the underside
of the circuit board with
your bare hands.
