(2) Cautions for handling and examples of dangerous handling for the product that the HDD is mounted on or the
HDD repair part
[Cautions for handling the product that the HDD is mounted on]
• The HDD is always in operation while the unit is turned on. Do NOT to apply shock to the unit.
Examples of dangerous handling: while the power is on
• Bumping the case
• Dropping an object, such as a small screwdriver or remote control unit, onto the case or bumping an object against the cabinet
• Physically dragging the unit
• Stacking another product on the unit
Note: Do NOT to apply shock, such as bumping or hitting a screwdriver against the HDD, during diagnosis with the case open.
Examples of dangerous handling: while the power is off
• Applying 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 lifting one side of the unit and letting it drop
• Do NOT move the unit immediately after the power is turned off. Wait at least 30 seconds after the indication on the FL display
changes from POWER OFF to the clock indication before moving the unit.
If the AC power cable is accidentally disconnected before turning the unit off, wait at least for one minute before moving the unit.
In this case, damage to the HDD caused by sudden shutoff may be small because the emergency relief mechanism is activated.
However, if sudden shutoff occurrs during recording or playback, recorded data may be damaged. Be sure to check the operations.
[Caution for handling the HDD repair part]
1. Handle the HDD in a safe environment:
• Handle the HDD over an antistatic pad that can also absorb shock.
• Wear wrist bands to prevent electrostatic charges generated in your body from affecting the HDD.
2. Observe the following rules when handling the HDD:
• Handle one HDD at a time. Do NOT hold several HDDs at the same time.
• Grip the HDD on both sides so that you do not touch its terminals or circuit boards.

• Do NOT stack one HDD onto another HDD (even if the HDDs are protected by antistatic bags).
• Do NOT bump the HDDs against one another.
• Do NOT bump any tool, such as a screwdriver, or other hard object against the HDD.
• When a repair part (HDD) is transported and there is a large temperature difference between the outside and inside temperature, leave
the HDD in its package for about half a day after it is moved inside to gradually cool or warm it to room temperature before unpacking.
