  2. 2. AVR-3808CI / AVR-3808 / AVC-3808 SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective. CAUTION Please heed the points listed below during servicing and inspection. Heed the cautions! Inspect for safety after servicing!Spots requiring particular attention when servicing, such as Check that all screws, parts and wires removed or discon-the cabinet, parts, chassis, etc., have cautions indicated on nected for servicing have been put back in their original posi-labels or seals.

AVR-3808CI / AVR-3808 / AVC-3808CAUTION IN SERVICINGInitializing AV SURROUND RECEIVER/AM-PLIFIERAV SURROUND RECEIVER/AMPLIFIER initialization should beperformed when the µcom, peripheral parts of µcom, and DigitalP.W.B. are replaced.1. Switch off the unit.2. Hold the following STANDARD button and DSP SIMULA- TION button, and switch on the unit.3. Check that the entire display is flashing with an interval of about 1 second, and release your fingers from the 2 buttons and the microprocessor will be initialized. Note: If step 3 does not work, start over from step 1. All user settings will be lost and this factory setting will be recovered when this initialization mode. So make sure to memorize your setting for restoring after the initialization. 1,2 2,3JIG to use for servicingWhen you repair the printing board, you can use the followingJIG (Extention cable kit).
