[1] Cautions on Handlin g the HDD
• The HDD is very sensitive to shocks and vi b rations. Care must b e taken especially during operation (when the power is on).
• The HDD is very sensitive to electrostatic charges.
• Rapid change in temperature or humidity may cause deterioration of the HDD.
N ote: After receiving damage caused b y any a b ove-mentioned factors, the HDD may operate normally for dozens or some
hundreds of hours b ut then suddenly crash. If you are certain you have damaged a new repair part (HDD) while making
repairs, do not use the part.
[2] Cautions on handlin g the product on which the HDD is mounted or the HDD
as a repair part, and examples of dan g erous handlin g
[Cautions on handlin g the product on which the HDD is mounted]
• W hile the unit is turned on, the HDD is always in operation. Be sure N OT to impart shock to the unit.
Examples of dan g erous handlin g : while the power is on
• Bumping on the b onnet
• Dropping an o b ject, such as a small screwdriver or remote control unit, onto the b onnet, or b umping an o b ject against the
ca b inet
• Moving the unit b y dragging
• Stacking another product on the unit
N ote: Be sure N OT to impart shock, such as b umping or hitting a screwdriver against the HDD, during diagnosis with the
b onnet open.
Examples of dan g erous handlin g : while the power is off
• Imparting strong shock, although the HDD is more resistant to shock when the power is off
• Dropping the unit from a height of several centimeters, or after lifting one side of the unit up, then letting the unit drop.
• Do N OT move the unit immediately after the power is turned off. W ait at least 30 seconds after the indication on the FL
display changed from PO W ER OFF to the clock indication b efore moving the unit. If the AC power cord is accidentally
disconnected b efore turning the unit off, wait at least for one minute b efore moving it. In this case, damage to the HDD
caused b y sudden shutoff may b e small, b ecause the emergency relief mechanism is activated. However, if sudden shutoff
occurrs during recording or play b ack, recorded data may b e damaged. Be sure to check operations.
[Cautions on handlin g the HDD as a repair part]
1. Handle the HDD in a safe environment:
• Handle the HDD over an antistatic pad that can also a b sor b shock.
• W ear wrist b ands to prevent electrostatic charges generated in your b ody from affecting the HDD.
2. The following must b e o b served when handling the HDD:
• Handle one HDD at a time. Do N OT hold several HDDs at the same time.
• Grip the HDD on b oth sides so that you do not touch its terminals or circuit b oards.
• Do N OT stack one HDD onto another HDD (even if the HDDs are protected in antistatic b ags).
• Do N OT b ump the HDDs against one another.
• Do N OT b ump any tool, such as a screwdriver, or other hard o b ject against the HDD.
• W hen a repair part (HDD) is transported and there is a large temperature difference b etween outdoors and indoors, to the
indoor, leave it in its package for a b out a half day to gradually cool or warm the HDD to room temperature b efore unpacking it.
[Notes on packin g for shipment]
• W hen returning a defective HDD for analysis, handle with care as if it were a good product. Otherwise, the results of analysis
may not b e correct.
• W hen packing, use the antistatic b ag and packing materials in which the repair part for service was delivered. Attach a copy
of the slip for service or a memo stating symptoms in as much detail as possi b le.
