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 (You may see an error message displayed stating this fact). 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. Clean the screen with a soft, damp cloth. You may use a mild cleaner intended for eye glasses or computer screens. To avoid scratching the panel, do not rub too hard, or use abrasive cleaners or shop towels. The touch panel consists of a touch sensitive resistive membrane covering the display. Unlike previous systems, you must actually ‘‘touch'' the display to activate it. Never use hard or sharp implements to operate the screen because you risk damaging the sensing membrane. If a touch ‘‘switch'' does not function immediately, shift your finger slightly, and touch it again. Note: The display is unaffected by sunlight, as in previous displays. |
