Environmental
conditions
Environmental
conditions
Although
this recorder
may
be used in either
the upright or horizontal positions, the
upright
position is preferred
from
the
point
of more efficient ventilation. Mounting
locations to be
avoided are;
Locations of constant high ternperature
Do not operate this unit near heating appliances
or on top of an amplifier where
amplifier heat would
contribute
to a rise
in temperature. Do not
place the
unit
where
it will be exposed to direct summer
sunlight.
Temperature
extremes will not only
cause degradation of
sound quality but will also shorten the usefuil operating life of
the unit. Avoid
temperatures
higher
than 100oF.
Locations of
extreme
low temperature
In low temperature locations
lubricants
will
harden
and satisfactory operation
cannot
be
expected.
Operation will
be
sluggish
and an overload may
be
placed
on
the
drive motors. Avoid
temperatures lower than
40"F.
Locations of
high
humidity
High humidity locations will shorten
equipment
life due to
corrosion and
possible
fungus
grorvth
on
printed
circuit
boards.
Dusty
environments
Your
TEAC recorder is
a
precision machine
and as such should be
protected
from
dust.
Operation
in a dusty atmosphere
will
result in excessive head and
bearing
wear.
Your tapes should also be kept
dust free.
Fluctuation of the supply voltage
Should
you
be
in
an area
where line
voltage fluctuation is severe, the use of an
automatic
voltage controller is recommended.
