Usage Cautions

Installation place In order to use the equipment for a long time, follow the instructions shown in below:

Do not install this equipment near a heat source such as direct sun light, a stove and so on.

Do not use this equipment at a poorly-ventilated, humid or dusty place.

Do not install this equipment at an unstable place such as a slope or a vibrating place.

Do not install this equipment near the window where the equipment can be exposed to rain.

Do not install this equipment in a high humid environment.

Avoid using this equipment on an equipment generating heat such as an amplifier.

Keep this equipment away from a power supply transformer or a motor of another equip-

Note

Avoid covering the equipment with a cloth or installing it in enclosed space because radiation and air convection from the chassis surface can be hindered.

To prevent external sound pressure and grit / dust from entering the equipment, inspiratory/exhaust ports to radiate the heat are not arranged against the equipment consciously. Radiating the heat from the equipment is done by cooling with air convection in the chassis and with radiation and air convection from the chassis having high thermal conductivity.

Useable AC power supply voltage and frequencies

AC 100V power supply must be supplied.

The equipment operates normally in both areas of 50Hz and 60Hz power supply frequencies.

Handling AC power cable

Do not touch the AC power cable with wet hands.

Do not pull the cable strongly or do not bend the cable. The cable can be damaged and can result in a risk of fire and electric shock.

Use the AC power cable of the accessories.

Repair

In case of the equipment failure consult the dealer.

Care of Equipment

If the equipment is covered with dust or dirt clean it with a soft cloth.

If the equipment is covered with heavy dust put a very thin mild detergent on a soft cloth.

Wring the cloth and wipe off the dust and dirt. Then clean with a dry soft cloth.

Never use chemical agents such as thinner, naphtha or alcohol when cleaning it.

If any of them is attached to the equipment, the silk printing can be flaked or the surface can lose metal luster.

Removing the vacuum tubes

(1) Remove the vacuum tube cover straight up.

(2) When removing the vacuum tube, you must hold the resin portion at the root of the vacuum

tube and pull it out. In case of holding the glass portion, the vacuum tube may break.

Cautions for handling the vacuum tube

Since the vacuum tubes are made of glass, they can be broken easily so they should be handled carefully.

After turning the power to OFF and waiting until the vacuum tubes cool well, you can remove them or mount them. In case the vacuum tube does not cool, this can result in a risk of failure, electric shock, or burns.

We measured the performance of the vacuum tubes of accessories and selected good ones.

In case a vacuum tube except our ones of accessories is used, this can result in a risk of performance deterioration or failure. The vacuum tubes of accessories should be used.

After mounting the vacuum tubes, the cover must be placed back. For the vacuum tube, a high voltage is applied in the operation and then they turn to a high temperature. In case you touch them or some object hits them, these can result in a risk of burnt injury, electric shock, or fire.

When an abnormal state occurs for the vacuum tubes, please contact your dealer.

Circle

Side assigning the circle

Long slot

A circle is assigned on one side of the plug of the AC power cable so that better sound quality is reproduced by matching the power supply polarity with another equipment.

This polarity may be different because of house wiring for outlet or because of the power supply condition; however, generally the side assigning the circle should be inserted to the long slot of the outlet.
