In low light conditions, you can increase the readability of the LCD
by using the backlighting feature. To activate backlighting, press the
ALT key three times. The backlight will shut off automatically if you
do not press any keys or use the trackwheel for more than 10
seconds.
Keyboard and trackwheel
The 31-key QWERTY keyboard provides access to all of the regular
alphabetic characters; numeric characters, a symbols library,
punctuation, and special characters can be generated using the
orange
ALT key in combination with the other keys. For easy typing,
hold the device in both hands and use your thumbs. Roll and click
the trackwheel for navigation and selection.
A trackwheel that clicks!
The trackwheel on the handheld has a unique feature for greater
usability and performance: it clicks! Pressing down on the
trackwheel with your thumb is comparable to the clicking function
of your PC mouse. Click to open menus and to select functions and
menu options.
Battery compartment
The handheld operates on one AA alkaline battery or one NiMH
rechargeable battery housed in the battery compartment at the back
of the handheld. See page 22 for more information on the battery.
Holster (belt clip)
A holster, equipped with a belt clip, accompanies the handheld.
While in the holster, the handheld is protected and wearable. You
can choose different forms of message notification based on whether
the handheld is in or out of the holster.
