SAFETY PRECAUTIONS
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precautions for this recording or playback
equipment. The following precautions are necessary during servicing:
1. Many electrical and mechanical parts in this recorder have
special safety-related characteristics for providing protection against shock, fire and other hazards. These characteristics often go unnoticed in a visual inspection, and the
protection afforded by them cannot necessarily be obtained by using replacement components with higher ratings (voltage, wattage, etc.).
2. Replacement parts having special safety-related characteristics are identified in this manual, and in the schematic
diagrams, by the symbol ! . These components have
values that are of special significance to product safety.
Should any component (identified by the symbol ) need
to be replaced, use only the part designated in the parts
List. Do not deviate from the specified resistance, wattage,
and voltage ratings.

3. Before returning the set to the customer, always perform an
AC leakage current check on the exposed metallic parts of
the cabinet, such as terminals, screwheads, metal overlays, etc. to be sure that the set is safe to operate without the
danger of electrical shock, Plug the AC line cord directly into
a 120 V AC outlet. (Do not use a line isolation transformer
during this check.) Use an AC voltmeter with a sensitivity of
5000 ohms per volt (or more) as follows: Connect a 1500
ohms, 10 watt resistor, paralleled by a 0.15 mfd, 150 VAC
capacitor, between a known good earth ground (water pipe,
conduit, etc.) and the exposed metallic parts, one at a time.
Measure the AC voltage across the 1500 ohms resistor and
0.15 mfd capacitor combination. Reverse the AC plug at the
AC outlet and repeat the AC voltage measurements for
each exposed metallic part. The measured voltage must
not exceed 300 mVrms. This corresponds to 200 µA AC.
Any value exceeding this limit constitutes a potential shock
hazard and must be corrected immediately.
4. Fuse symbol marks.

CAUTION "Risk of fire-replace fuse as marked"
Fuse rating is marked at

NOTES ON HANDLING INTERNAL HDD COMPONENTS
This unit has a built-in hard disk drive (HDD).
Be sure to observe the following points carefully when operating, setting-up and servicing the unit.
1. Do not subject the unit to shocks or vibration.
If the unit is subjected to shocks or vibration, it may
damage the HDD or cause corruption of the data stored in
the HDD.
• Do not move the unit while the power is turned on.
Always be sure to turn off the power before removing the
unit from or placing it onto the rack.
• When transporting the unit, pack it securely using the
specified packing materials. In addition, use a method of
transportation that minimizes vibration.
• When placing the unit down on a surface such as a floor,
attach the specified feet to the base of the unit and place
it down gently. If the feet are not attached, place the unit
down very carefully so that it does not make any noise.
2. Do not move the unit for 30 seconds after turning
off the power.
After the power is turned off, the disk inside the HDD will
continue to spin for a brief period due to inertia, and the
heads will be in an unstable state.
During this time, the unit is even more susceptible to
shocks and vibration than when power is being supplied.
Make sure that the unit is not subjected to even gentle
vibration for at least 30 seconds after turning off the
power.
3. Do not operate the unit when condensation has
formed.
If the unit is operated when condensation has formed, it
may cause operating problems.
If sudden changes in the ambient temperature occur, wait
for the temperature to stabilize before operating the unit.
4. Notes when replacing the HDD
Be sure to follow the correct replacement procedure when
replacing the HDD.
• HDDs that have been removed from their packaging may
not operate correctly if they are subjected to any shocks
or vibration. It is recommended that you place the HDD
onto a soft, level surface with the printed circuit board
facing upward after unpacking it.
• Be careful not to subject the HDD to shocks or vibration
when removing and tightening screws as part of the HDD
replacement procedure. Make sure that all screws are
tightened securely so that they will not become loose.
• The HDD is sensitive to static electricity, so you should
take proper precautions to prevent static electricity
buildup.
5. Handling the HDD unit by itself
If transporting or storing the HDD unit by itself, always be
sure to pack it in the specified packaging first.
In addition, use a method of transportation that minimizes
vibration.
If the HDD becomes damaged, handle the unit and the
damaged HDD that has been removed in order for it to be
replaced carefully to prevent the problem from being
aggravated until as the nature of the problem can be
checked and analyzed.
