WARNING
The flexible mains lead is supplied connected to a B.S. 1363 fused plug
having a fuse of 5 AMP capacity. Should the fuse need to be replaced,
use a 5 AMP FUSE approved by ASTA to BS 1362, ie one that carries the
mark.
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE
FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD BE CUT
OFF AND AN APPROPRIATE PLUG FITTED. THE PLUG SEVERED
FROM THE MAINS LEAD MUST BE DESTROYED AS A PLUG WITH
BARED WIRES IS DANGEROUS IF ENGAGED IN A LIVE OUTLET
SOCKET.
When an alternative type of plug is used it should be fitted with a 5 AMP
FUSE, otherwise the circuit should be protected by a 5 AMP FUSE at the
distribution board.

T
How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.

GE-1A SELF DIAGNOSTIC SOFTWARE
The identification of errors within the GE-1A 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 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 dis-
played through the LED (Series of flashes which must be counted) See table 1., non fatal errors are reported using this method.
