2.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 suuply cord and nickel screw on the back
panel.
Specifications: 3.3Mohm ±10% at 500V.
5. Changing the band step
With the exception of the models below, a BAND STEP
selector switch is not provided.

determined, is on the back panel side of the tuner circuit
printed circuit board assembly test points TP-1 and TP-2.

3-Change of voltage
Worldwide models are equipped with a voltage selector to
conform with local power supplies. This switch is located
on the back panel. Be sure to set this switch to match
the voltage of the power supply in your area before
turning the power switch on.
This swith is set to 220V at the factory. Voltage is
changed by sliding the groove in the switch with the
screwdriver to the right or left. Confirm that the switch
has been moved all the way to the right or left before
turning the power switch on.
4.Step band selector switch
Worldwide models are equipped with a step band selector
switch. This switch is located on the back panel. This
switch is set to 50kHz (FM) and 9kHz (AM) at the factory,
but may have to be reset to 100kHz and 10kHz depending on
the area where the unit is used.
De-emphasis FM step AM step
Europe: 50// sec 50kHz 9kHz
U.S.A.: 75//sec 100kHz 10kHz
6.Memroy preservation
This unit does not require memory preservation batteries.
A built-in memory power back-up system preserves 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 that since 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 period of time during which memory contents are
preserved after power has last been turned off varies
depending on climate and placement of the unit.
On the average, memory contents are protected over a
period of 3 to 4 weeks (a minimum of 2 weeks) after
the last time power has been turned off. This period is
shorter when the unit is exposed to very high humidity or
used in an area with an extremely humid climate.

FM control signal output terminal. "L" when FM.
AM control signal output terminal. "L" when AM.
AM local oscillator input terminal.
FM local oscillator terminal.
Power supply terminal for back-up.
Power supply terminal.
Charge pump output of the phase detector which constitutes the PLL. High level is output when the
divided local oscillator frequency is high than the reference frequency.
In the opposite case, low level is output. Floating occurs when the frequencies matched.
The output is applied to the variable capacitor diode in the local oscillator through the low pass
filters.
Ground terminal.
