Safety Precautions
This Plasma Display is for use only with the following optional accessor\
ies. Use with any other type of optional 
accessories may cause instability which could result in the possibility \
of injury.  
(All of the following accessories are manufactured by Panasonic Corpora\
tion.)
   CAUTION
 
 When using the Plasma Display
Do not bring your hands, face or objects close to the 
ventilation holes of the Plasma Display.
• 
Top of the Plasma Display is usually very hot due to the 
high temperature of exhaust air being released through the 
ventilation holes. Burns or personal injuries can happen if any 
body parts are brought too close. Placing any object near the 
top of the display could also result in heat damages to the object 
as well as to the Display if its ventilation holes are blocked.
Be sure to disconnect all cables before moving the Plasma Display.• Moving the Display with its cables attached might damage 
the cables which, in turn, can cause  fi re or electric shock.
Disconnect the power plug from the wall outlet as a 
safety precaution before carrying out any cleaning.
•  Electric shocks can result if this is not done. Clean the power cable regularly to prevent it from 
becoming dusty.
•  Built-up dust on the power cord plug can increase humidity which might damage the insulation and cause  fi re. Unplug 
the cord from the wall outlet and clean it with a dry cloth.
This Plasma Display radiates infrared rays, therefore it 
may affect other infrared communication equipment.
Install your infrared sensor in a place away from direct 
or refl  ected light from your Plasma Display.
Note:
Do not allow a still picture to be displayed for an extended 
period, as this can cause a permanent image retention to 
remain on the Plasma Display.Examples of still pictures include logos, video games, computer 
images, teletext and images displayed in 4:3 mode.

Safety Precautions
WARNING 
The front of the display panel has been specially treated. Wipe the panel surface gently using only a cleaning 
cloth or a soft, lint-free cloth.
• 
If the surface is particularly dirty, wipe with a soft, lint-free cloth which has been soaked in pure water \
or water in which n eutral 
detergent has been diluted 100 times, and then wipe it evenly with a dry\
 cloth of the same type until the surface is dry.
•  Do not scratch or hit the surface of the panel with fi  ngernails or other hard objects, otherwise the surface may become 
damaged. Furthermore, avoid contact with volatile substances such as ins\
ect sprays, solvents and thinner, otherwise 
the quality of the surface may be adversely affected.
If the cabinet becomes dirty, wipe it with a soft, dry cloth. •  If the cabinet is particularly dirty, soak the cloth in water to which a small amount of neutral detergent h\
as been added and then wring the cloth dry. Use this cloth to wipe the cabinet, and then wipe it dry with a dry cl\
oth.
• Do not allow any detergent to come into direct contact with the surface \
of the Plasma Display. If water droplets get  inside the unit, operating problems may result.
•  Avoid contact with volatile substances such as insect sprays, solvents an\
d thinner, otherwise the quality of the cabinet  surface may be adversely affected or the coating may peel off. Furthermore, do not leave it for long periods in contact 
with articles made from rubber or PVC.
Maintenance
 Setup
Do not place the Plasma Display on sloped or unstable 
surfaces. •  The Plasma Display may fall off or tip over.
Do not place any objects on top of the Plasma Display. • 
If water spills onto the Plasma Display or foreign objects get 
inside it, a short-circuit may occur which could result in  fi re or 
electric shock. If any foreign objects get inside the Plasma 
Display, please consult an Authorized Service Center.
Do not cover the ventilation holes. • Doing so may cause the Plasma Display to overheat, which can cause  fi re or damage to the Plasma Display.
Transport only in upright position! •  Transporting the unit with its display panel facing upright or downward may cause damage to the internal circuitry.
If using the pedestal (optional accessory), leave a space 
of 3 
15/16” (10 cm) or more at the top, left and right, and 
2 3/4” (7 cm) or more at the rear, and also keep the space 
between the bottom of the display and the  fl oor surface. 
If using some other setting-up method, follow the manual 
of it.  (If there is no speci fi c indication of installation 
dimension in the installation manual, leave a space of 
3 
15/16” (10 cm) or more at the top, bottom, left and right, 
and 2 3/4” (7 cm) or more at the rear.)
When installing the Plasma Display vertically;
Turn up the power switch for the upward direction when you 
install the Plasma Display vertically.
And set “DISPLAY ORIENTATION” to “PORTRAIT” in SET 
UP menu. 
An apparatus with CLASS I construction shall be 
connected to a mains socket outlet with a protective 
earthing connection.
 AC Power Supply Cord
The Plasma Display is designed to operate on 110 - 127 
V AC, 50/60 Hz.
Ensure that the mains plug is easily accessible. Do not use any power supply cord other than that 
provided with this unit.
•  Doing so may cause  fi re or electric shocks.
Securely insert the power cord plug as far as it will go.• If the plug is not fully inserted, heat may be generated 
which could cause  fi re. If the plug is damaged or the 
wall socket plate is loose, they should not be used.
Do not handle the power cord plug with wet hands. •  Doing so may cause electric shocks.
Do not do anything that might damage the power cable. 
When disconnecting the power cable, hold the plug, 
not the cable. •  Do not make any modifi  cations, place heavy objects on, 
place near hot objects, heat, bend, twist or forcefully 
pull the power cable. Doing so may cause damage to 
the power cable which can cause  fi re or electric shock. 
If damage to the cable is suspected, have it repaired at 
an Authorized Service Center.
If the Plasma Display will not be used for a long period 
of time, unplug the power cord from the wall outlet.
 If problems occur during use
If a problem occurs (such as no picture or no sound), 
or if smoke or an abnormal odor is detected from the 
Plasma Display, unplug the power cord immediately. • Continuous use of the Display under these conditions might cause  fi re or permanent damage to the unit. 
Have the Display evaluated at an Authorized Service 
Center. Services to the Display by any unauthorized 
personnel are strongly discouraged due to its high 
voltage dangerous nature.
If water or foreign objects get inside the Plasma Display, 
if the Plasma Display is dropped, or if the cabinet 
becomes damaged, disconnect the power cord plug 
immediately. • A short may occur, which could cause  fi re. Contact an 
Authorized Service Center for any repairs that need to be 
made.
