Operation of the unit elevates the temperature of the IC
package.  Heated IC package may result in injury.
Replace the IC after turning off the power and ample time

for the IC to cool off.

The EEPROM (IC102) on the IF-716 board store the
following data.

IC102 (D4/IF-716)

Model and Serial No.

n
As for the IC102 on the IF-716 board, it is impossible to
write the original data into a new IC.

When replacing the IF-716 board, remove the IC102 on the

new IF-716 board and replace with the used IC on the

former board.

If it becomes necessary to replace with a new IC, contact

your local Sony Service Center/Sales Office.

The RE-160 and RE-161 boards and electrical parts

mounted on its boards cannot be replaced.

If these parts are out of order, replace the whole DC-DC

converter.

The bearing of the DC fan is a precision part. Be careful

not to grasp the fan by its blade, bump, and drop it.

Unduly shock may damage the bearing in the fan, that can

result in abnormal noise during the fan operation.
