Panasonic Projector Pt Lb80e Operating Instructions

							Precautions with regard to safety
ENGLISH - 11
Important 
InformationAvoid setting up in places which are subject to 
vibration or shocks.
 The internal parts can be damaged, which may cause 
malfunctions or accidents.
Avoid setting up in places which are subject to 
sudden temperature changes, such as near an air 
conditioner or lighting equipment.
 The life of the lamp may be shortened or the projector 
may be turned off. See “TEMP indicator” on page 41.
Do not set up the projector near high-voltage power 
lines or near motors.
 The projector may be subject to electromagnetic 
interference.If installing the projector to the ceiling, ask a 
qualified technician to carry out all installation work.
 You will need to purchase the separate installation kit. 
Furthermore, all installation work is should only be 
carried out by a qualified technician.
If using this projector at high elevations, 1 400 - 
2 700 m (4 593 - 8 858 ft) sea level, set the ALTITUDE 
to HIGH. See “ALTITUDE” on page 37.
 Failure to observe this may result in malfunctions or 
the life of the lamp or the other components may be 
shortened.
 Do not use the projector at high elevation higher than 
2 700 m (8 858 ft).
In order to get the best picture quality
 Draw curtains or blinds over any windows and turn off 
any lights near the screen to prevent outside light or 
light from indoor lamps from shining onto the screen.
Optical components
 If you use the projector consecutively 6 hours every 
day, the optical components may need to be replaced 
in less than 1 year.
Liquid crystal panel
 Do not project the same image for long periods of 
time, as this may remain as an afterimage on the 
liquid crystal panel. Display the white screen test 
pattern for more than an hour to remove it. See 
“TEST PATTERN” on page 38.
 The liquid crystal panel of the projector is built with 
very high precision technology to provide fine picture 
details. Occasionally, a few stuck pixels may appear 
on the screen as fixed points of blue, green or red. It 
is recommended to switch off the projector once and 
try after 1 hour later again. Please note that this does 
not affect the performance of your LCD.The projector has a high pressure mercury lamp and 
that is characterised as follows:
 The brightness of the lamp depends on the duration 
of use.
 The lamp may explode or shorten the lamp life by 
shocks or chipping damage.
 The lamp may explode only occasionally after using 
the projector.
 When the lamp exploded, it emits the internal smoke-
like gas.
 The lamp may explode if using the projector after the 
instructed lamp replacement timing.
 The lamp life is depends on individual lamp 
characteristics, usage condition and the installation 
environment. Especially the consecutive use of the 
projector for more than 10 hours, or the frequent 
switching on or off may greatly affect on the lamp life.
Do not touch the surfaces of the lens cover with your 
bare hands.
 If the surface of the lens cover becomes dirty from 
fingerprints or anything else, this will be magnified 
and projected onto the screen.
Take safety measures for use of the projector which 
should cover the following envisioned incidents.
 The leakage of your personal registered information.
 Dishonest operation by an untrusted third party.
 Locking out or prevent anyone else from using the 
projector by an untrusted third party.Security instruction
 Change your password regularly.
 Do not use too simple password to guess.
 Any of Authorised Service Centres will never ask you 
for the password.
 Do not share your password with the general public.
 Secure the network environment by the firewall.

Setting up
You can adjust the projection size with 1.2x zoom lens. Calculate and define the throw distance as follows.
* All measurements above are approximate and may differ slightly from the actual measurements.
JCalculation methods for screen dimensions
You can calculate more detailed screen dimension from the screen diagonal.
 Screen width (SW) and screen height (SH)
SW (m) = SD () x 0.0203 SH (m) = SD () x 0.0152
 Minimum distance (LW) and maximum distance (LT)
PT-LB80NTE: LW (m) = 0.0296 x SD () - 0.039 LT (m) = 0.0358 x SD () - 0.047
PT-LB75NTE: LW (m) = 0.0292 x SD () - 0.036 LT (m) = 0.0351 x SD () - 0.044
* The results above are approximate and may differ slightly from the actual measurements.

NOTE:
• See “Screen size and throw distance for 16:9 aspect ratio” on page 49.
• Do not use the projector at a raised or a horizontally tilted position as it may cause 
malfunction of the projector.
• You can tilt the projector body approximately ± 30° vertically. Overtilting may result in 
shortening the component’s life.
• For the best quality of the projection image, install a screen where sun light or room light 
does not shine directly onto the screen. Close window shades or curtains to block the lights.

Connections
 Read and follow the operating and connecting instructions of each peripheral device.
 The peripheral devices must be turned off.
 One RGB cable is provided with the projector. If necessary, prepare commercial connecting cables that match 
with the projector and each peripheral device terminals.
 If the input signal is affected by signal jitter, the projected image may have poor image quality and timebase 
correction is effective.
 Confirm the type of video signals. See “List of compatible signals” on page 46.
 When you connect more than one AV equipment, switch the audio connection manually.
JConnecting with VIDEO IN/S-VIDEO IN

Connecting example: AV equipment
Connecting example: Computers
NOTE:
• When COMPUTER2 SELECT in the OPTION menu is set to OUTPUT, do not connect any input signals.
• Outputting signals from the COMPUTER 1 OUT terminal to multi connected device(s) may result in signal deterioration.
