Clean the DC plug of dust and other debris regularly
If dust or other debris accumulates on the plug, humidity, etc. may cause a defect in the insulation, which may result in a fire.
zPull the plug, and wipe it with a dry cloth.
Pull the plug if the computer is not being used for a long period of time.
Do not pull or insert the DC plug if your hands are wet
May result in electrical shock.
Insert the AC plug completely
If the plug is not inserted completely, fire due to overheating or electrical shock may result.
zDo not use a damaged plug or loose electrical socket.
Do not place metal objects or contain- ers of liquid on top of the computer
zIf water or other liquid spills, or if paper clips, coins, or other metal objects get inside the computer, fire or electrical shock may result.
Do not place the computer on unstable surfaces
If balance is lost, the computer may fall over or drop, resulting in an injury.
Do not move the computer while the DC plug is connected
The AC cord may be damaged, resulting in fire or electrical shock.
zIf the AC cord is damaged, remove the DC plug immediately.
Hold the plug when unplugging the AC cord
Pulling on the cord may damage the cord, resulting in a fire or electrical shock.
Do not turn the volume up to loud when using headphones
Listening at high volumes that overstimu- late the ear for long periods of time may result in loss of hearing.
Take a break of 10-15 minutes every hour
Using the computer for long periods of time may have detrimental health effects on the eyes or hands.
Do not look into the DVD-ROM & CD-R/ RW drive
Looking directly at the internal laser light source may result in damage to eyesight.
Do not use disks that are cracked or deformed
Because the disks rotate at high speeds, damaged disks may break apart causing injury.
zDisks that are not round and disks that have been repaired using adhesives are similarly dangerous, and so should not be used.
Do not cover the computer with a thick cloth, such as a blanket
Preparations
Precautions (Wireless LAN) <Only for models with wireless LAN>
Turn off*1 inside of airplanes
Radio waves may obstruct the safe oper- ations of the aircraft. Follow the instruc- tions of the airline with regard to use on airplanes.
Do not use near automatic doors, fire alarms, and other automatic control devices
Radio waves from this computer may affect automatic control devices, resulting in damage due to malfunctions.
Turn off*1 in hospitals and other loca- tions with electrical medical devices (do not bring into operating rooms,
intensive care units, CCUs*2, etc.)
Radio waves from this computer may affect electrical medical devices, resulting in damage due to malfunctions.
Turn off*1 in hospitals and other loca- tions with electrical medical devices (do not bring into operating rooms,
intensive care units, CCUs*2, etc.) Radio waves from this computer may affect electrical medical devices, resulting in damage due to malfunctions.
Turn off*1 in crowded areas, as per- sons wearing heart pacemakers may be nearby
Pacemaker operations may be affected by radio waves.
*1 | If it is necessary to use the computer in |
| these types of environments, turn the wire- |
| less LAN power off using the wireless LAN |
| switch. Note, however, that use of comput- |
| ers even while the wireless LAN is off may |
| be prohibited during takeoff and landings, |
