21.5 Cleaning the display screen
A coating is applied to the display screen. This makes it water
repellent, and prevents glare. To avoid damaging this coating, follow
this procedure:
1. Switch off the power to the display.
2. Rinse the screen with fresh water to remove all dirt particles
and salt deposits.
3. Allow the screen to dry naturally.
4. If any smears remain, very gently wipe the screen with a clean
microfibre cleaning cloth (available from an opticians).
