1. Replacing the fuses
3. Safety-check out
(Only U.S.A. model)
After correcting the original service problem perform the
following safety check before releasing the set to the customer
Connect the insulating-resistance tester between the plug of
power supply cord and terminal GND on the back panel.
Specifications: More than 10Mohm at 500V
This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse , For fuse rating, refer to
the marking adjest to the symbol.
Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu le present symbol est apposre.
1. Press and the hold down the VIDEO 1 button , then press the
SPEAKER A button when the nuit is Power ON.
2. After " CLEAR " is displayed, the preset memory and each mode
stored in the memory, are initialized and will return to the
factory settings.
2. To initialize the unit
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 un-plugged.
The unit must be plugged in order to charge the back-up
system.
The memory preservation period after the unit has been unplugged
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 the unit has been unplugged. This pe-riod
is shorter when the unit is exposed to a highly humid cli-mate.

REF. NO. PART NO. DESCRIPTION
This device employs a microprocessor to perform various
functions and operations. If interference generated by an external
power supply, radio wave, or other electrical souce results in accident
which causes the specified operations and functions to operate
abnormally.
To perform a result, please follow the procedure below.
With the exception of the worldwide models, a tuning step selector
switch is not provided. When you change the band step, change
the parts as shown below.
To 10kHz To 9kHz
R7020 Open 10k
R7021 10kohm 8.2kohm
4. Memory Preservation
7. Changing the AM band step
5.Setting the AM tuning step frequency
(World wide models only)
6.Setting the voltage selector
(Worldwide models only)
Worldwide models are equipped with a switch that controls
the AM band tuning step. Please set this switch to match the
AM band tuning step frequency in your area.
World models are equipped with a voltage selector
conform with local power supplies. Be sure to set this switch to
match the voltage of the power supply in your area before
plugging in the unit.
Determine the proper voltage for your area: 230V or 120V.
If the preset voltage is not correct for your area, insert a screwdriver
into the groove in the switch. Slide the switch all the way to the right
(120V) or to the left(220V-230V), whichever is appropriate.
