AT2XRM-EA001 / RM-ED001
The circuit boards used in these models have been processed usingLead Free Solder. The boards are identified by the LF logo locatedclose to the board designation e.g. F1, H1 etc [ see examples ]. Theservicing of these boards requires special precautions to be taken asoutlined below.
CAUTION
Lead Free Soldered Boardsexample 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 isavailable 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 requiressoldering 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

AT2X SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AT2X chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In theevent 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 continuousflashing 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 relevantdevice number will be displayed through the LED (Series of flashes which must be counted).
Flash Timing Example : e.g. error number 3
