LCD Display Unit Limitations

In cold temperatures, the display may stay dark for the first 2 or 3 minutes until it warms up.
When the display is too hot because of direct summer sunlight, it will remain dark until the temperature drops.
When the humidity is high and the interior temperature is low, the display may appear cloudy. The display will clear up after some use.
Fingerprints on the touch panel may sometimes be noticeable because of the panel's low-reflection coating. When cleaning the panel, wipe it gently with a soft cloth. To avoid scratching the panel, do not rub too hard.
The touch panel is an infrared system, so there is no need to press hard. If a touch switch does not function immediately, shift your finger slightly on the switch, and touch it again.
Input may be affected by direct sunlight.
