5. CHECKUP AND MAINTENANCE
(2) Cleaning a keyboard (optional)
When you clean a keyboard, make sure you follow the instructions below:
Do not spray detergent directly on to the keyboard or spill liquid detergent on it.
Do not wipe the keyboard with a wet cloth. If you do, the equipment may fail.
When you use detergent, spray a minimum amount of detergent on a cloth.
Before wiping the keyboard with a wet cloth, wring out the cloth well.
Use a soft cloth such as gauze.
Before using detergent, carefully read the instructions on use of the detergent.
Cover the whole keyboard with gauze, spray detergent all over it, leave it for a couple of
minutes, and wipe off the keyboard.
