FM Antenna Connections
Use the T-shaped antenna if you live in an area where signal strength
of FM broadcasts is high. Connect the antenna to the FM 75 ohms
terminals and place the antenna on a wall or other surface in the
position in which reception is best. If signal strength is low in your
area, use a multi-element FM outdoor antenna. Consult your Onkyo
authorized service center about the right type of antenna for your
area.
Directional linkage
NOTES: type splitter
1. Do not connect both the indoor T-shaped antenna and an
outdoor FM antenna. If you decide to install an outdoor
antenna, be sure to disconnect the indoor T-shaped antenna.
Do not use the same antenna for both FM and TV reception
To receiver To TV (or VCR)
since the FM and TV signals can interfere with each other.
tf you must use a common FM/TV antenna, use a directional
linkage type splitter.

AM Antenna Connections
An AM loop antenna is included in the installation instructions bag.
Take out the connection line and connect it to the AM antenna
terminals. This {oop antenna can be placed on top of any stable
surface or attached to a wall. Try several positions to determine
which gives the best reception. Be sure the antenna is not near a
speaker, power cord, television set, VCR, or motorized appliances.
When using an externa! AM antenna, do not remove the loop an-
tenna; connect both antennas to the AM antenna terminals.

Memory Preservation
This unit does not require memory preservation batteries. A
built-in memory power back-up system preserves the contents
of the memory during power failures and even when the unit
is unplugged. The unit must be plugged in and the power switch
turned on and off once in order to charge the back-up system.
Note thatsince this is not a permanent memory, the power switch
must be turned on and off a few times each month to keep the
back-up system operative.
The memory preservation period after power has been turned
off varies depending on climate and placement of the unit. On
the average, memory contents are protected over a period of a
few weeks after the last time power has been turned off. This
period is shorter when the unit is exposed to a highly humid
climate.

Bw
Direct function feature (TX-820 only)
NOTE:
This function works when an Onkyo cassette tape deck or CD
player with the {QI mark is connected to a TX-820 withan
fRI remote contro! cable.
Just by directly operating the desired component (compact disc
player, or tape deck), the TX-820’s input selector automatically
switches to that component. The component that was being used
stops, and the desired component starts operation. Therefore, it
is not necessary to switch the TX-820’s input selector when
changing listening sources. Another way to switch listening sources
is to press the TX-820’'s input selector of the desired fistening source.
The current listening source will then stop automatically and the
desired listening source wil] start operation.
Example 1
When the compact disc player's play button is pressed, the TX-8 20's
input selector will switch automatically to “CD.” If the current lis-
tening source was a tape deck, tape playback will stop and the
compact disc player will start playing.
Example 2
With a tape deck as the current listening source, if the TX-820's
input selector is switched to “CD,” the tape deck will stop playing
and the compact disc player will start playing.
NOTES:
@ The direct function feature does not apply to turntable.
@ Insome cases, the direct function may not work the first time
the input selector is pressed.
Pressing the input selector again will enable the direct
function. (This is to prevent irregular unit operation.)

Batteries
The remote control transmitter is powered by two batteries.
Before using this unit for the first time, insert the two batteries
(included) as shown in the diagram. The remote control trans-
mitter has no on/off switch. Average battery life is one year.
This period may be shorter depending on the frequency of use
and environment (temperature and humidity) in which the re-
mote control transmitter is used. If the remote control transmitter
does not operate even though front panel controls function
normally, the batteries should be replaced. Use only batteries
listed in the following chart.
. Do not leave an expired battery in the case as it may leak or
damage the battery case.
. When inserting the batteries, be sure the (+) and (—): ends
are properly aligned.
. Do not use nickel-cadmium (rechargeable) batteries.
. Do not use one specified (manganese) battery and one al-
kaline battery at the same time.
. Replace both batteries at once; do not use one old and one
new battery together.

Precautions
. Remove the batteries if the remote control transmitter is not going
to be used for a long time.
The batteries of the remote control transmitter must be replaced
periodically. Remember, however, that commands will be re-
ceived only when the power switch of the TX-820 is on.
This unit uses infrared rays. Therefore, commands may not be
received properly if the front panel of the TX-820 is exposed
to bright light. To prevent this from occurring, place the TX-820
so that it is not directly exposed to a bright light.
If the TX-820 is placed inside an audio rack behind a glass door,
the door should not use colored glass or have any decorations
on it since this could shorten the range or prevent commands
from being received.
Use of other infrared remote control devices in the same room
may cause interference.
The transmitter operates up to a distance of about five meters
(16 feet). the transmitting window must always be pointed at
the reception window when a command is sent to the TX-820.
If this remote control transmitter does not operate properly,
confirm that the batteries are not dead. If the problem persists,
contact your Onkyo service center.
