Operation Notes
Condensation
In winter, moisture droplets may form on the window panes of a heated room. This phenomenon is called
condensation. Condensation may occur with this unit or with cassette tape in the following situations:
¢ ina room where a heater has just been turned on
* ina room where steam or excessive moisture are present
* when the unit is brought in suddenly from a cold place toa warm room
¢ when the unit is directly in the path of cold air from an air conditioner, etc.
In such cases, the unit will not operate correctly, and even if it does operate, the tape may be damaged. In
particular, if moisture condenses on the rotating heads, the tape will stick. This will prevent the tape from
running properly, and might damage it.
If condensation occurs
To protect the tape, this unit contains a built-in device so that when condensation occurs, the dew indicator on
the display panel flashes. While the dew indicator is flashing, apart from the OPEN/CLOSE function, buttons
on the unit will not operate.
If a cassette tape is loaded in the unit, remove it and leave the power switched on. Wait until the indicator goes
out. The time required for moisture to evaporate will vary according to the environment, but itmay be 60 minutes
or longer if humidity is high. Condensation usually sets in gradually, so the indicator may not flash for the first
10~15 minutes. If room temperature or humidity changes abruptly, therefore, wait for about 20 minutes before
switching on power to check that the indicator is not flashing.
Operating the unit
Always keep the cassette holder closed. If it is left open, dust will accumulate in the mechanism and cause tape
playback or recording performance to deteriorate. Do not touch the inside of the cassette holder.
The top of the deck will become hot during use, but this is perfectly normal.
Keep the replay volume low. With DAT (Digital Audio Tape recorder) cassettes, there is much less noise than
with compact cassettes and a wider dynamic range. There will be a sudden burst of sound when the audio
material begins. As this may damage the speakers, due care should be taken. Be especially careful when using
headphones.
Dynamic Range
Dynamic range is the difference between the lowest sound level and highest sound level, and is expressed in
decibels (dB). The greater this difference, the more dynamic the recording.
When carrying or storing the unit, take care not to subject it to any severe shocks. When storing or transporting
the unit, also be sure to remove the cassette tape.
