The duration of backlight of keypad synchronizes with LCD backlight’s.
4.6. Using Screen Protectors
Handheld defines proper use of the terminal touch panel display as using a screen protector and proper stylus. Screen
protectors maintain the ongoing integrity (i.e., prevent scratching) of the touch panel, which is why their use is
recommended for applications that require a high to medium level of interface with the touch panel.
Handheld also mandates use of the proper stylus, which is one that has a stylus tip radius of no less than 0.8mm. Use of
the stylus included with the terminal is recommended at all times.
4.7. Installing Your Screen Protector
When installing a screen protector, use a flat plastic card (e.g., credit card) to apply the screen protector smoothly and
remove any air bubbles.
1. Press the Power key to put the terminal in suspend mode.
2. Clean the touch panel thoroughly with a clean, non-abrasive, lint-free cloth, Make sure nothing is on the touch panel.
3. Blue tag with backing film: Peel off this mask before application.
