For Canada model

THIS DIGITAL APPARATUS DOES NOT EXCEED THE 'CLASS B"

LIMITS FOR RADIO NOISE EMISSIONS FROM DIGITAL APPARATUS SET OUT IN THE RADIO INTERFERENCE

REGULATION OF THE CANADIAN DEPARTMENT OF COMMUNICATIONS.

CAUTION: READ THIS BEFORE OPERATING YOUR UNIT.

On drum life

It is recommended to replace the head drum with a new one within about 1,500 hours of use.

1. This unit is a sophisticated digital audio tape recorder. To ensure proper operation for the best possible performance, please read this manual carefully.

2. Before using this unit for the first time, wait 1 to 2 hours after plugging the AC power cord into the wall outlet.

3. Choose the installation location of your unit carefully. Avoid placing it in direct sunlight or close to a source of heat. Also avoid locations subject to vibration and excessive dust, heat,

cold or moisture. Keep it away from sources of hum such as transformers or motors. If interference in TV or radio reception occurs during operation, increase the distance

between the two components.

4. Do not open the cabinet as this may result in damage to the deck or electrical shock. If a foreign object should drop into the deck, contact your local dealer.

5. When removing the power plug from the wall outlet, always pull directly on the plug; never pull the cord itself.

6. Do not apply excessive force when operating switches and knobs.

7. When moving the deck. be sure to first pull out the power plug and remove all cords connecting the deck to other equipment.

8. Do not attempt to clean this unit with chemical solvents as this may damage the finish. Use a clean, dry cloth.

9. If the unit does not work properly while in use, after turning the POWER switch OFF, disconnect the AC power cord plug from the AC outlet and wait for about 30 seconds. After that,

connect it again to operate.

Dew condensation

Dew is the moisture that collects on a cold object in a warm room. Dew can form on the drum and head inside the tape deck causing damage to tapes and head. This unit contains a dew prevention heater. Once the unit is connected to an AC outlet, the heater turns on to prevent dew from forming. It takes from 1 to 2 hours to remove dew. When dew is detected on the drum

and head, the "DEW" indicator appears and the unit does not operate. Wait about 1 to 2 hours after the display returns to

normal before using the unit. Dew forms easily: In highly humid and steamy rooms. When carrying the unit from a cold place to a warm room.

* Use the unit at room temperatures from 5° C to 35° C. Dew

forms especially easily in cold temperature regions.

Amplifier volume adjustment

Digital audio tapes produce considerably less noise than regular records and cassette tapes, and are extremely quiet between programs. Be careful not to raise the volume too high and exceed the amplifier and speaker ratings.

Recommended amplifier input impedance is 600 ohms or higher. Connecting an amplifier (or other external audio device) having an input impedance that is too low may decrease the level of the

output.

Rack mount

The front panel of this unit conforms to the 2U size standards and can directly be installed in the 19 inch rack. However, if the space of the rack is small, remove 4 legs from the bottom panel, then install the unit in the rack. If the rack is not well ventilated,

the temperature inside the rack becomes high. Be sure to keep the rack well ventilated.

10. Be sure to read the "Troubleshooting" section of this manual for advice on common operating errors before concluding that your unit is faulty.

11. Keep this manual in a safe place for future reference.

Cleaning the head

When the head is slightly dirty, noise is heard or dropouts occur during playback. If the head becomes excessively dirty, a signal read error occurs during playback, and the sound cannot be heard. At this time, the "WARNING" indicator appears. If this

occurs, use a commercially available digital audio cleaning tape or have your Yamaha dealer clean the head. After prolonged

use, the head may require replacement due to wear. Consult

your Yamaha dealer.
