Only one internal scanner is installed in the 7535 G2, but a second hand-held scanner can be connected
via the tether port. Internal scanners can be triggered from the trigger switch on the 7535 G2’s handgrip
(if present) or from the Scan button on the 7535 G2’s keyboard. External scanners can only be triggered
from their own trigger switch.
1.4.5 The Display
The 7535 G2 is available with a 240x320-pixel display, either monochrome (64 shades of grey) or colour
(256k colours). The contrast of the display can be adjusted from the keyboard via hot-keys, and is
automatically temperature-compensated.
1.4.5.6 Touch Input
Touch input is an option for the 7535 G2’s display. The touch driver controls the hardware directly to
receive touch-down, touch-up, and movement events. Touch events are passed to the application via the
operating system.
1.4.5.7 The Display Backlight
The 7535 G2 has a backlight behind its display. This backlight can be adjusted for intensity, and can be
configured to turn on when the ambient light level drops below a configured value.
