Note
 zThe number of display dots of PT

-LZ370U is 1 920 x 1 080.
A signal with a different resolution will be projected after converting the resolution to match the projector 
display.
 z The “i” at the end of the resolution indicates an interlaced signal.
 zWhen interlaced signals are connected, flicker may occur on the projected image.

 zWhen installing the projector to a ceiling, be sure to use the specified ceiling mount bracket (ET
-PKA1 10H: for 
high ceilings, ET-PKA110S: for low ceilings).
 z Installation work of the ceiling mount bracket should only be performed by a qualified technician.
 zPanasonic takes no responsibility for any damage to the projector resulting from use of a ceiling mount bracket 
not manufactured by Panasonic or the inappropriate choice of location for installation, even if the warranty 
period of the projector has not expired.
 zAn unused ceiling mount bracket must be removed promptly by a qualified technician.
 zUse a torque screwdriver or 

Allen torque wrench to tighten bolts to their specified tightening torques. Do not 
use tools such as electric screwdrivers or impact screwdrivers.
 z For details, read the installation manual that comes with the ceiling mount bracket.
 zThe part numbers of accessories and separately sold components are subject to change without notice.
