Additional information
LCD display
•
Small black or shining points may appear on the LCD display. This is a phenomenon
inherent to LCD displays and not a malfunction.
•
When using the unit in cold places, the LCD display may be dark for a while after the power
is turned on. Normal brightness will restore after a while.
•
When the LCD display is exposed to direct sunlight, the light will reflect off it, making it
difficult to see. Block the direct sunlight to improve visibility of the display.
Cleaning
Wipe with a dry soft cloth.
•
Do not use organic solvents, acids or alkalis for cleaning.
Touch screen
•
Operate the touch screen with your fingertip. Do not press it with excessive force.
•
Do not operate the touch screen with hard and sharp-pointed objects such as a ballpoint
pen, mechanical pencil, or sharp fingernail.
