PROTECTOR OPERATION CHECK
Thermal Protect
1. Short across TH801 with the power on.
2. Verify that the protector is operated and LD801 illuminates red.
3. Verify that the protector is released and LD801 illuminates green
when the short is removed.
4. Likewise, perform items 1 to 3 for TH802.
Over Current Protect
1. Short between the positive and negative sides of the speaker
output terminal CN802 with the power on.
(Perform this shorting for each channel on L and R.)
2. Verify that the protector is operated and LD801 illuminates red.
3. Verify that the protector is not released and LD801 remains red
even when the short is removed.
4. Verify that the protector is released and LD801 illuminates green
when the power is turned off and then on again.
Offset Protect
1. Short between the +12V terminal of CN801 and the BTL+ or
BTL– of the speaker output terminal CN802.
(Short between +12V terminal and BTL+ and between +12V
terminal and BTL–.)
2. Verify that the protector is operated and LD801 illuminates red.
3. Verify that the protector is not released and LD801 remains red
even when the short is removed.
4. Verify that the protector is released and LD801 illuminates green
when the power is turned off and then on again.
Chassis Short Protect
1. Short between the +12V terminal of CN801 and the chassis with
the power on.
2. Verify that the pilot lamp PL801 goes on.
3. Verify that PL801 goes off when the short is removed.

•RESISTORS
All resistors are in ohms.
METAL:Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F:nonflammable
•Items marked “*” are not stocked since
they are seldom required for routine service.
Some delay should be anticipated
when ordering these items.
