WARNING (UK Models only)
The flexible mains lead is supplied connected to a B.S. 1363 fused
plug having a fuse of 13 AMP rating. Should the fuse need to be
replaced, use a 13AMP FUSE approved by ASTA to BS 1362, ie one
that carries the
plug having a fuse of 13 AMP rating. Should the fuse need to be
replaced, use a 13AMP FUSE approved by ASTA to BS 1362, ie one
that carries the
ASA
T
mark.
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUIT-
ABLE FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD

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 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).
