Precautions
CAUTION:
These servicing instructions are for use by qual-
ified service personnel only. To reduce the risk of elec-
tric shock do not perform any servicing other than that
contained in the operating instructions unless you are
qualified to do so.
• Do not block the ventilation opening or slots on the
cover.
To prevent the apparatus from overheating, place it at
least 5 cm {2 inches} away from the wall.
• Do not drop metallic parts through slots.
This could permanently damage the apparatus. Turn
the power off immediately and contact qualified service
personnel for service.
• Do not attempt to disassemble the apparatus.
To prevent electric shock, do not remove screws or
covers.
There are no user-serviceable parts inside. Contact
qualified service personnel for maintenance.
• Do not strike or give a strong shock to the unit.
It may cause damage or allow water to enter the unit.
• Do not expose the apparatus to water or moisture.
Do not try to operate it in wet areas.
Take immediate action if the apparatus gets wet. Turn
the power off and refer servicing to qualified service
personnel. Moisture can damage the apparatus and
also cause electric shocks.
• Built-in backup battery
Before the first use, charge the built-in backup battery
(lithium battery) by turning on the power for 48 hours or
more. If it is not charged enough, in a case where the
power goes down, the internal clock may keep bad
time or the operative condition may be different to that
before the electric power failure.
The built-in battery life is approximately 5 years as an
indication of replacement. (This is just an indication of
replacement. We are not providing any guarantee of the
built-in battery lifetime. Replacement cost of the built-in
battery is not covered by the warranty even if it needs
to be done within the warranty period.) Ask the shop
where you purchased the unit when replacement of the
battery is required.
• Cooling Fan
Turn the power off when cleaning the unit. Otherwise it
may cause injuries.
The cooling fan will operate for approximately 30 000
hours. Replacement costs of the cooling fan are not
covered by the warranty even if it needs to be done
within the warranty period.
• Cleaning
Turn the power off when cleaning the unit. Otherwise it
may cause injuries.
Do not use strong or abrasive detergents when clean-
ing the apparatus body.
Use a dry cloth to clean the apparatus when it is dirty.
When the dirt is hard to remove, use a mild detergent
and wipe gently.
• Do not operate the apparatus beyond its specified
temperature, humidity, or power source ratings.
Use the apparatus under conditions where tempera-
tures are between –10 °C and + 50 °C {14 °F to 122 °F},
and humidity below 90 %.
The apparatus may not work properly after turning on in
a cold atmosphere between –10 °C and 0 °C {14 °F to
32 °F}. Wait approximately 10 minutes until the inside
temperature has risen to 0 °C {32 °F}, it can work prop-
erly.
The input power source for this apparatus is 220 V to
240 V AC, 50 Hz.
• Place the unit horizontally on a level surface. Do not
place the unit in an upright position. When stacking
multiple units, clear a space of more than 5 cm {2
inches} from both sides, the top, the bottom and the
rear of the units.
• Pay attention to static electricity
Make certain to keep boards inside the anti-static sack
until it is installed.
Put your hand on a metallic surface, other than the
boards to discharge static electricity before installation.
Do not touch components mounted on the boards
directly by hand.
Hold only both edges of the boards when installing.
• Do not use any power cord other than the one sup-
plied.
Use the power cord that is suited to your locality.
• Only use the apparatus indoors.
Do not install it in places where the apparatus is
exposed to sunlight for long periods of time or near air
conditioning equipment. This will cause deformation,
discolouration, breakdown or malfunction.
• We recommend that you make a note of your set-
tings and save them. This will help when you are
required to change the system configuration, or
when unexpected trouble or failure occurs.
• Distributing, copying, disassembling, reverse com-
piling, reverse engineering, and also exporting in
violation of export laws of the software provided
with this product, is expressly prohibited.
