Using the Rugged Handheld Device
3.1.2 Text Input
The GT-500 doesn't have a physical keyboard to receive user's text input. To
input text on the device, it relies on the "onscreen keyboard" featured by the
operating system. An "onscreen keyboard" is a virtual keyboard with most of
the standard keys.
To open the onscreen keyboard, simply tap a text input field and the keyboard
appears.
3.1.3 Sleep Mode
When the device suspends to sleep mode, it enters a low power state and the
display is off to save the battery power. You can manually force the device to
enter sleep mode or specify a period of inactivity before it automatically enters
sleep mode. While the device is in sleep mode, it is still capable of receiving
messages and calls and processing tasks like downloading.
To switch to sleep mode, press and hold the Power key until the screen is
turned off.
To wake up the device from sleep mode, press and hold the
Power
key until
the screen is turned on. If the screen is locked, swipe up to unlock the device.
To specify the period of inactivity, tap
