The module keeping condition
* The normal temperature condition (more
than 15°C) > Immediately the line supply.
* The module keeping condition: 0°C > The module must be kept for more than 2 hours at the normal temperature.
* The module keeping condition: -20°C > The module must be kept for more than 3 hours at the normal temperature.
* The case of Gu-mi factory at the winter season. > The module must be kept for more than 5 minutes at the heating zone (40°C~45°C)
* The module keeping condition: 0°C > The module must be kept for more than 2 hours at the normal temperature.
* The module keeping condition: -20°C > The module must be kept for more than 3 hours at the normal temperature.
* The case of Gu-mi factory at the winter season. > The module must be kept for more than 5 minutes at the heating zone (40°C~45°C)
Because this is not a hot chassis, it is not necessary to use an
isolation transformer. However, the use of isolation transformer will help
protect test instrument.
> Adjustment must be done in the correct order.
> The adjustment must be performed in the circumstance of 25±5°C of temperature and 65±10% of relative humidity if there is no specific designation.
> The input voltage of the receiver must keep 100~240V, 50/60Hz.
> The receiver must be operated for about 5 minutes prior to the adjustment.
After RGB Full White in HEAT-RUN Mode, the receiver must be operated prior to the adjustment.
