General Information on Servicing
Note the following information when servicing the monitor.
WARNING
To avoid the possibility of injury to yourself or damage to the

CAUTIONS
Safety
• There is the possibility that the outside surface of the monitor, such
as the operation keys, could be contaminated by contagious germs
so disinfect and clean the monitor before servicing it. When
servicing the monitor, wear rubber gloves to protect yourself from
infection.
• There is the possibility that when the lithium battery or LCD unit is
broken, a solvent could flow out or a toxic substance inside it could
come out. If the solvent or toxic substance contacts the eyes or skin,
wash immediately and thoroughly with water and see your physician.
Never rub your eyes, otherwise you may lose your eyesight.
• To avoid accidental electrostatic discharge which could damage the
components of the monitor, use a grounded wrist strap when
installing or removing any component of the monitor.
• Use a pair of clean cotton gloves when replacing the LCD unit. If it is
damaged, your hand may get injured.
Liquid ingress
The monitor is not waterproof, so do not install the monitor where
water or liquid can get into or fall on the monitor. If liquid
accidentally gets into the monitor or the monitor accidentally falls
into liquid, disassemble the monitor, clean it with clean water and dry
it completely. After reassembling, do the patient safety checks and
function/performance checks to verify that there is nothing wrong. If
there is something wrong with the monitor, contact your Nihon
Kohden representative for repair.
