Touchscreen
The Trex unit has a resistive touchscreen that lets you select menu items and enter text.
Firmly press the screen to select an item. You need to apply more pressure than you would
for smart phones and tablets. If the touchscreen seems inaccurate, you can re-calibrate it.
All instructions in this manual are written for the touchscreen.
The touchscreen supports basic gestures, such as scroll up and scroll down. Multi-touch
gestures, such as pinch, are not supported.

 CAUTION
The touchscreen display on the Trex unit could be damaged if directly impacted. To avoid
damaging the touchscreen:
•
Use the Trex carrying case with the faceplate closed to protect the touchscreen and
prevent any damage when transporting or carrying the Trex unit.
•
Do not let the touchscreen come in contact with other objects.
•
Contact the touchscreen with blunt items only. Sharp instruments, such as
screwdrivers, can damage the touchscreen.
Repairing the touchscreen requires replacement of the entire display assembly, which is
possible only at an authorized service center.
 CAUTION
Do not use a screen protector on an IS-approved Trex unit. Static discharge is possible.

Supported gestures
The Trex unit uses a single-tap to select an item on the screen. You do not need to double-
