CAUTION
Lead Free Soldered Boards
example 1
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.

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 :
Partnumber 7-640-005-19 7-640-005-20 7-640-005-21 7-640-005-22 7-640-005-23 7-640-005-24 7-640-005-25 7-640-005-26

Remarks 0.25Kg 0.50Kg 0.50Kg 0.25Kg 1.00Kg 1.00Kg 1.00Kg 1.00Kg
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.

WA1 SELF DIAGNOSTIC SOFTWARE
The identification of errors within the WA1 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).
