during the preset time. If the screen saver operates, press any key to restore the display.
CAUTION
• Condensation may form on the LCD screen if the GL400/350 is moved from a cold to a warm
location. If this occurs, wait until the LCD screen warms up to room temperature.
•The LCD screen is manufactured to extremely high precision. Black dots may appear, or red, blue,
and green dots may not disappear. Likewise, streaks may appear when viewed from certain angles.
These phenomena are due to the LCD screen construction, and are not signs of a fault.
1.6 Changing the Display Language
You can choose either English or Japanese as the language displayed on the screen. The default display
language is set to English when the GL400/350 is shipped overseas. To change the display language, see
