Note: This image transmission device has a temperature protection function.
When the temperature of the image transmission device exceeds 100°C,
the transmission power of the image transmission device will be reduced by
one level. If the temperature remains above 100°C, the transmission power
will be reduced by another level until it reaches the lowest power level
(25mW). At this point, the temperature of the image transmission device
will decrease. When the temperature drops to 95°C, the transmission
power will return to the originally set power level.
