Precautions

•Refer all work related to the installation of this appa- ratus to qualified service personnel or system installers.

•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 be not linked to a network 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 be linked to a network.

The input power source for this apparatus is 120 V AC, 60 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.

•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, discoloration, 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.
