2 • Installation and precautions - General care and maintenance
To lock and unlock the head, use the slider on the bottom of the main unit (see
the illustration below):
2.3 General care and maintenance
The YPDR is a precision piece of electronic equipment. Avoid exposing the
YPDR to extremes of temperature or humidity.
Avoid exposing the YPDR to a dusty or smoke-filled environment. Clean the sur
faces of the YPDR with a dry, lint-free cloth. Do not use spray cleaners, thinners
or solvents. A little mild detergent applied to a slightly damp cloth may be used
to remove stubborn stains or grease marks.
There are no user-serviceable parts inside either the main unit or the controller.
Do not disassemble the YPDR. Refer to a Yamaha service center for any repairs
or adjustments.
ALWAYS
use the head lock system when transporting or moving the YPDR,
even for a short distance.
When recording, only use blank discs of a type recommended by YAMAHA.
Use of any other kind of disc may not give satisfactory results, and may even
result in damage to the YPDR.
2.4 Warm-up and condensation
The main unit requires 30 minutes after power-on before it can be used. Allow
this amount of time after switching on the unit before attempting recording.
If the main unit is brought into a warm room from a cold environment, internal
condensation may occur. Allow between 1 and 2 hours for the unit to acclima
tize before attempting operation.
2.5 Care of discs
Optical audio discs and CDs are robust storage media, but the rules below
should be followed in order to extend their usable lifetime:
•
Do not expose discs to direct sunlight or bright light of any kind, and keep
them away from strong sources of heat. Avoid storage or use in places
which have a high humidity. If the discs become damp, allow them to dry
naturally, or use an air stream to dry them.
•
Before using a disc for recording, remove any dust particles, etc. using an
air stream (gently blow). If any dust particles cannot be removed using this
method, clean the disc with a lint-free cloth. Wipe the non-label side of
the disc radially from center to edge. Do not wipe in a circular path. Do
