the computer and the keyboard.
If there is a failure of any sort, disconnect any other USB devices (not your
mouse or Single Hand Keyboard) and then restart your computer.

4. KEYBOARD CLEANING
PLEASE DISCONNECT THE KEYBOARD FROM MAINS POWER BEFORE CARRYING
OUT MAINTENANCE.
The outer shell and other external surfaces can be wiped clean with a soft damp cloth.
Do not use any cleaning solvents on your keyboard. A weak solution of regular washing
up liquid can be used if necessary.
You can remove the key caps to access the switch panel. This allows cleaning of the
switch panel, again with a soft damp cloth. One of the many advantages to owning a
Maltron keyboard is the keyboard can be rinsed under a warm tap to wash away liquid
stains such as tea, coffee or juices.

STATIC AND YOUR KEYBOARD
Static electricity in your office is very erratic and will change from day to day with the
weather, with the central heating and with ventilation. It also changes with the clothes
worn by people in the office (nylon is one of the worst) and the number and types of
VDUs you use. It often collects on objects such as curtains, light switches and VDU's -
depending on air circulation. You need to know this so that you can identify if any
factors in your office are causing a build up of static.
Static shocks are usually noticed when you hear crackling (try wiping a dusty TV or
VDU screen after it has been on for a while). However, "small" static shocks of 50 or
100volts go largely unnoticed by humans, but if this hits digital electronic equipment,
then the equipment often cannot cope and becomes unreliable.
Like any piece of electronics, the Maltron keyboard does not like being hit with static.
However unlike most other pieces of electronic equipment, it is touched every day by
people who move around picking up static charges from computer VDUs, curtains,
chairs and carpets. Even just taking off a coat with a nylon lining or getting up from a
chair, can charge a person up several 1000 volts. If the charged person then touches
the keyboard immediately, its electronic brain gets a shock. To avoid this particular
problem, always touch an earthed body before the keyboard when starting work, and
