|
Operating (non-condensing) .................... ............................................................... |
20% to 85% |
Non-Operating (38.7°C maximum wet bulb temperature........ ........... .................... |
5% to 85% |
1-6-3 Altitude |
|
Operating ............................................................... ...................... ...................... |
(0 to 2,000 m) |
Non-Operating............................... .................................... ........ . ...................... |
(0 to 3,000 m) |
1-6-4 Vibration and Shock |
|
All testing shall be done in each of three mutually perpendicular axes, referenced to the position of the system as it is in front of the user (i.e., front-to-back, side-to-side, and top-to-bottom).
2 Precautions and Notices
2-1 Precaution of assembly
1 Please do not press or scratch PDP panel surface with anything hard.
2 Please wipe out PDP panel surface with absorbent cotton or soft cloth in case of it being soiled3 Please wipe out drops of adhesive like saliva and water in PDP panel surface immediately. They might
damage to cause panel surface variation and color change4 Do not apply any strong mechanical shock to the PDP panel
2-2 Precaution of Operation
1 Please be sure to unplug the power cord before remove the back-cover. (make sure the power is turn-off)2 Please do not change variable resistance settings in PDP MODULE; They are adjusted to the most
suitable value. If they are changed, it might happen LUMINANCE does not satisfy.
3 Please consider that PDP MODULE takes longer time to become stable of radiation characteristic in low temperature than in room temperature.
4 Please pay attention to displaying the same pattern for very long-time. Image might stick on PDP.
