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