Display Backlight

Dolphin terminals ship with a screen protector already installed over the touch screen lens to help
prevent damage to the touch screen. Do NOT remove this screen protector before initial use.
Honeywell recommends using screen protectors, especially for applications that require high-
volume interfacing with the touch screen. For more information, see
page 3-4.
For touch screen input, use the stylus included with the terminal or your finger. The method you choose
depends on which one is most appropriate for your application. While there is a great deal of variation in
different applications, for buttons or icons that are close together, you generally achieve greater accuracy
with the stylus; see Using the Stylus
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 touch screen display has a backlight that is programmed to turn off after a specified period of time
that the terminal is idle. For details, see

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 Dolphin 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. Please contact a Honeywell
sales associate 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.
Honeywell warranty policy covers wear on the touch panel display for the first 12 months provided that a
screen protector is applied and an approved stylus is used for the 12 month duration covered by the
warranty.
Removing the Screen Protector
Dolphin terminals ship with a touch screen protector already installed. To replace the screen protector,
you must remove the one already installed.
