PRECAUTIONS
1. Replacing the fuses
For continued protection against risk fire, replace only with same type and same rating fuse.
CIRCUITNO. PARTNO. DESCRIPTION
F901 252051 6A ST-6, Primary fuse (120V, 120V/220V models)
F902 252076 or 3. 15A-SE-EAK or
252076CC 3. 1SA-SE-EAK Primary fuse (220V, 240V, 120V/220V models)
2. Insulation resistance mesurement (Only U.S.A. model)
Connect the insulating-resistance tester between the plug of power supply cable and the terminal GND on the
back panel.
Specifications; More than 10 MQ at 500V.
3. Voltage selector (rear panel)
Worldwide models are equipped with a voltage selector to conform with local power supplies. Be sure to set this
switch to match the voltage of the power supply in your area before turning the power switch on. Voltage is
changed by sliding the groove in the switch with a 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. Models without a voltage selector
can only be used in areas where the power supply is the same as that of the unit.

ADJUSTMENT PROCEDURES
Adjustments and Checking the Protection Circuitry
1. Preparations
1) Place the unit on the workbench. (There should be about 15 mm of space between the base plate of the unit and
the work surface.)
2) Set up the unit as follows.
(1) No load
(2) No signal
(3) Volume turned all the way down
(4) Speaker switch OFF
(5) Power switch OFF
Note) Check the following points before making adjustments
(1) The power switch should be OFF.
(2) The interior of the unit should not be warm.
2. Idling current adjustment
1) Turn the power switch ON and allow the unit to warm up for about 10 minutes.
(1) Adjust R535 (R635) so that the voltage at test point VCT-IID on the NAAF-3601 circuit board is 15mV+S5mV.
Note) Semi-fixed resistors enclosed in parentheses ( ) are for the right channel.
3. Check of operation of protection circuitry
1) Check of operation of protection relay
(1) Confirm that the relay turns ON approximately 5 seconds after the power switch is turned ON.
(2) The SERVO indicator LED should light at the same time.
(3) The relay should turn OFF approximately 0.5 seconds after the power switch is turned OFF.
2) Check of DC detection and servo circuitry operation
(1) Turn the power on with no load.
(2) After the speaker relay turns ON, apply DC+200mV to the CD input terminals. Confirm that the relay turns OFF.
(3) Confirm that operation is the same as (2) above when an input of DC—200mV is applied.
Note) Under no circumstances connect a load or short the speaker terminals when performing the above test.
3) Signal input from the circuit illustrated below with no load.
(1) Confirm that the speaker relay does not turn OFF even when a 2 ohm load is connected when a peak value of 30V
p-p ts output.
(2) Next, confirm that when a 1 ohm load is connected the speaker relay switchse OFF and ON a couple of times
and then stays OFF.
Note) The period before that relay stays OFF should not last for more than | minute.
Relay OFF status can be canceled by switching the power OFF.
