2.11 Special care must be taken in transporting or handling it. Exquisite shock vibration may lead to
breakage of screen glass or damage to driving circuit. Therefore it must be packed in a strong case
before the transportation or handling.
2.12 For the storage make sure to put it in a place where the environment can be controlled so as to
prevent the temperature and humidity from exc eeding the limit s as spe cified in the manual. For
prolonged storage, it is necessary to house it in an anti-moisture bag andput them altogether in one
place. The ambient conditions are tabulated as follows:
Temperature
Humidity
Scope for operation

0 ~ +50 oC
-20 ~ +60 oC
20% ~ 85%
10% ~ 90%
2.13 Display of a fixed picture for a long time may result in appearance of pict ure residue o n the

4페이지 h) Check if the color coordinates of th e cool/warm color temperature at YPbPr (includ e 480i,
480P, 720P, 1080i), VI DEO(NTSC, PAL) and TV channels are within the scop e of the
corresponding value (permit ±8 error).
5 Functional Inspection
5.1 TV function
Connect RF terminal to the central signal source, Enter Search menu → auto search, check if there
is station skipping. Check if Fine Tune, the out put of earphone and sp eakers, and the picture are
normal. Check STEREO/SAP/CCD/Parent Control and the picture and sound from AV-OUT.
5.2 ATSC function
Connect AIR terminal to the central signal source, press INFO button and check if the information is
right. Open EPG table and do the same check. Open CCD, V-CHIP and check the display.
5.3 AV/S-Video terminal
Separate input A V1/S/AV2 signal, check if they are normal. Check if th e picture an d sound fro m
AV-OUT is normal. It should auto-jump to S terminal when insert S-terminal at the status of AV1.
5.4 VGA terminal
Input VGA s ignal (VG849 signal ge nerator), sep arate input the VGA fo rmat signal of t able 1 and
check if the display and sound are normal. If the image is slight disturb, press auto correction button
on the remote control and check the display.
