5.1 General.
1. All specifications must be met over line voltage range of 90V
AC
to 264V
AC
50Hz / 60Hz, unless otherwise
specified.
2. Operating temperature range is 0
o
C to 40
o
C with a relative humidity of 10% or less to 80%.
3. The monitor must be operational in a usable state within 30 minutes after turn-on.
4. All signal levels are measured assuming termination at the monitor’s input jacks or in its characteristic impedance.
5. All controls must have excess range (no control may be left at an end stop when proper alignment is completed).
6. The monitor is not required to meet specs under the following circumstances, but must tolerate without
damage to the LCD or circuits any sequence or combination of: Power on and off, signal on and off,
erratic or incorrect frequency, noisy inputs, any possible combination of unplugging of power or signal
cables, or any setting of user accessible controls. Likewise, the monitor should survive extended
periods of operation with line voltage reduced below the specified minimum.
7. An isolation transformer should be used when performing alignment and tests. Portions of the power
supply board are hot ground. The remaining boards are cold ground.
8. Ambient condition:
8.1 Illumination: In usual inspection of electric performance and mechanical performance, it shall be 150 ~
260lux.
8.2 Environmental noise: Less than 60dB.
8.3 Interference of EMI: The inspection shall be carried out in a place where the set is not disturbed by
excessive external electric waves or magnetic fields.
