Use of objects, such as paper clips, pencils, or ink pens on the touch screen can damage
the input panel and may cause damage not covered by the warranty.
Display Backlight
The intensity of the backlight of the touch screen display may be changed, and the backlight may be
programmed to turn off after the terminal has been idle for a specified period of time.
To adjust the intensity of the backlight while on battery power, tap Start > Settings > Control Panel >
double tap Backlight.
Screen Backlight - Battery/External Power
Move the slider to adjust the screen backlight while on battery power.
You may turn the screen backlight off if the device is not used for a designated
period of time by checking the option and designating the desired time period.
You may also turn on the screen backlight when a button is pressed or the
screen is tapped by selecting the appropriate checkbox.
Note: Using the backlight option while on battery power substantially reduces battery
life.
You may make the same changes when on external power by tapping the
External tab.

the backlight may be programmed to remain on for a specified period of time
once a key is pressed.

to adjust the backlight while on battery power.
To turn on the keyboard backlight, check the checkbox and change the
duration of the backlight.
Using Screen Protectors
Honeywell 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.
Honeywell continues to advocate the use of screen protectors on all Optimus 5900 RFID terminals. We
recommend implementing a screen protector replacement program to ensure that screen protectors are
replaced periodically when signs of damage/wear are noticeable. For general use, we recommend
replacing the screen protector every thirty (30) days. However, replacement cycles vary according to the
average level of touch panel use in your application.
Replacement screen protectors can be purchased directly from Honeywell. Contact a Honeywell sales
representative for details.
Honeywell also mandates use of a proper stylus, which is one that has a stylus tip radius of no less than
0.8mm. Use of the Honeywell stylus included with the terminal is recommended at all times.
