Initial Light Conditions
When power is initially applied to the Cooktop, the touch control
conducts a calibration process for the touch keys, which requires a
low level of ambient light in the area of the touch keys.
If during this calibration process excessive ambient lighting is
detected the User Interface displays "FL" (Infrared Ambient Light
Error) and the control calibration process is suspended. In order to
rectify the process any lighting that could affect the calibration
process should be switched off (e.g. halogen cooker hood lighting).
The error will disappear when satisfactory ambient lighting is
detected and the touch control calibration procedure will now
complete satisfactorily.
Notes:
1) The "FL" error can only be generated within approximately 3s of
initial power being applied to the cooktop.
2) We recommend that the user switches off all cooker hood
lighting and any lighting directed towards the cooktop when power
is initially applied to the cooktop.
3) After the touch control has conducted its initial calibration
process, (approximately 3s) any cooker hood or other lighting can
be switched on as normal and will not affect the operation of the
touch control.
