together, it is not easy for the user to see when liquids

have fallen onto the circuitry below the keys.

Attempting to clean the keyboard with a spray on

cleaner or rag soaked with cleaner the liquid can drip

onto the circuitry sight unseen. Once the liquid seeps

between the layers of circuitry, it can cause corrosion or

other damage to the circuits. This can result in keys

which no longer operate, or which, when pressed, record

the wrong characters and other similar failures.

There is no repair for this problem other than replace-

ment. The solution is to become aware of the issue and

take appropriate steps to protect your keyboard.

Cleaning should be done with a rag dampened (but not

soaking) with cleaning solution. Use extreme care to

prevent liquid from dripping between the keys. Spraying

directly on the keys should be avoided. The spray should

be applied first to the cloth, and then the cloth wiped

over the keys.
