General information regarding the TFT display
The time and date are buffered by a 3V 210 mAh, CR2032 type
button cell. If, therefore, the time should be incorrect or the
clock should stop working, this button cell must be replaced.
It is mounted on the reverse of the circuit board
j
of the
LCD display. To replace this button cell, the LCD display must
be removed from the furniture front by carefully clipping the
chrome-plated frame out of its holder. You will then see the
screws that fasten the plastic part to the furniture. Loosen the
-
se screws to detach the display.
When replacing the button cell, please ensure that plus
and minus are in the right direction. Incorrect polarity may
cause the display to become defect.
