The flexible mai ns lead is supplied connect e d to a B.S. 1363 fused plug
having a fuse of 5 AMP capacity. Should the fuse need t o be replaced,
use a 5 AMP FUSE approved by ASTA to BS 1362, ie one that c arries the
ASA
T
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 ENGAGE D IN A LIVE OUTLET

When an alte rnative type of plug is used it sho u ld be fitted with a 5 AMPFUSE, otherwise the circuit should be protected by a 5 AMP FUSE at the
distribution board.
How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.

SET-UP ADJUSTMENTS
•When comp lete readjustment is necessary or a new
picture tube is installed, carry out the following
adjustments.
•Unless there are specific instructions to the contrary,
carry out these adjustments with the rated power supply.
•Unless there are specific instructions to th e contrary, set the
controls and switches to the following settings :
Contrast............... 80% [or remote control normal]
Brightness............... 50%
Preparation:
1.In order to reduce the influence of geomagnetism on the set’s
picture tube, face it in an easterly or westerly direction.
2.Switch on the TV set’s power and degauss with the
degausser.
3-1. BEAM LANDING
1.Input an all-white signal from the pattern generator.
Set the Contrast and Brightness to normal.
2.Set the pattern generator raster signal to all Red.
3.Move the deflection yolk forward and adjust with the purity
control so that the Red is at the centre and the Blue and Green
take up equally sized areas on each side of the screen.
[See Fig.3-1 - 3-3].
4.Move the deflectio n yolk forward and adjust so that the entire
screen becomes Red. [See Fig.3-1].
5.Switch the raster signal to Blue, then to Green and verify the
purity condition.
6.When the position of the deflection yolk has been determined,
fasten the deflection yolk with the screws.
7.If the b eam does not land correctly in all the corners, use
magnets to correct it. [See Fig.3-4].
Carry out the following adjustments in this order :

bring the centre of the screen into focus.
Note :Bring only the centre area of the screen into focus, switch to an
all-white pattern and confirm that the magenta ring is hardly
noticed. To obtain optimum focus balance the focus setting
between optimum screen centre focus and a reduced magenta
ring level.

4-3. FE-1 SELF DIAGNOSTIC SOFTWARE
The identification of errors within the FE-1 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 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.
