SECTION 1 GENERAL

The circuit boards used in these models have been processed using

Lead Free Solder. The boards are identified by the LF logolocated

close to the board designation e.g. F1, H1 etc [ see examples ]. The

servicing of these boards requires special precautions to be taken as

outlined below.

Lead Free Soldered Boardsexample 1

example 2

Lead Free Solder material must be used to comply with environmental requirements of new solder joints. Lead Free Solder is available under

the following part numbers :

Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires

soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

For more information on the use of Lead Free Solder, please refer to http://www.sony-training.com

SE2AG SELF DIAGNOSTIC SOFTWARE

The identification of errors within the SE2AG chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the

event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous

flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant

device number will be displayed through the LED (Series of flashes which must be counted).
