CAUTION

Lead Free Soldered Boards

The circuit boards listed below [Table 1] used in these models
may have been processed using Lead Free Solder. The boards are
identified by the LF logo located 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.

Table 1

example 1

example 2

It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality 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

AE-6B SELF DIAGNOSTIC SOFTWARE

The identification of errors within the AE-6B 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) See table 1, non fatal errors are reported using this
method.
Each time the software detects an error it is stored within the NVM. See Table 2.
