Q: 

On/Off-Button

A: 

Switches standby mode on or off. This button does not switch the device completely off. As a result, you can continue working immediately after pressing the button again.

Q: 

LED

A: 

The left LED indicates the battery charge condition. Green indicates a charged battery, Orange is shown during the charging process and Red indicates an error.
The right LED signalises in Green, if a label has been read successfully by the scanner. Red signalises an error. Furthermore Bluetooth shows its availability in Blue, while WLAN, WWAN or GPS use Orange.

Q: 

Touchscreen

A: 

The screen reacts to touch. The input fields on the screen can either be selected with the input pen or the finger.

Q: 

Trigger-Keys

A: 

The scanner can read data from a label. By pressing one of the trigger-keys the scanner will be activated while the scanner software is running. Further keys can be configured if necessary.

Q: 

Cursor-Keys

A: 

The cursor-keys serve in principle to change between switching surfaces represented on the screen or to move the insert mark in input fields.

Q: 

Keypad

A: 

Via the keypad you enter numbers and letters. To switch between numbers and letters use the key [ALPHA]. In the status line at the upper edge of the screen the selected input method is shown symbolically.

Q: 

Enter-Key

A: 

With the enter key inputs are finalised. Thus the program is instructed to accomplish the action chosen by you, for example use a selected button or store an entered number.

Q: 

[CLR]-Key

A: 

The CLR-Key ("Clear"-Key) deletes the marked data in an input field, or rather the character left to the cursor. The key combination [Fn] + [CLR] leaves the actual screen if it is a simple dialogue window.

Q: 

[Fn]-Key

A: 

With [Fn] - key additional input functions can be activated. In the status line at the upper edge of the screen the activated [Fn] - key is shown symbolically. By the gradual combination of an [Fn] - key and a further key you will reach the following functions:
 
[Fn] + [0] Fade in or out the software input panel
[Fn] + [1] Switch on or off the screen backlight
[Fn] + [2] Switch on or off the keyboard backlight
[Fn] + [3] -
[Fn] + [4] Calibration of the touch screen
[Fn] + [5] Darken the backlight
[Fn] + [6] Brighten the backlight
[Fn] + [7] Starts a program (full path must be saved to Registry)
[Fn] + [8] Starts a program (full path must be saved to Registry)
[Fn] + [9] Starts a program (full path must be saved to Registry)
[Fn] + [CLR] Display the functional character ESC
[Fn] + [.]  Display the character "-"

These key combinations are pre-installed and can be deactivated via the Registry.

Q: 

Keyboard Backlight

A: 

You can manage the keyboard backlight either by using the key combination [Fn] + [2] or from within your own application by calling SysKeyBacklightOff, SysKeyBacklightOn, and SysKeyBacklightState from our System Library.

Q: 

[F]-Keys

A: 

The F-Keys [F1] to [F4] are related to their counterparts that you already from PC. Under Windows Mobile, they have also special meaning. If an software application comes with a menu that contains two entries, those entries will be displayed as "softkeys" at the bottom of the screen. You can activate the softkeys by either touching them directly or by pressing [F1] for the left and [F2] for the right softkey. On devices with phone module, [F3] initiates a phone call, while [F4] closes it. As a result, you cannot assign new functions to the key codes from F1 to F4. If you do not want use those special functions, you will have to assign new key codes to the hardware keys from [F1] to [F4] by using our System Library API.

Q: 

[Alpha]-Key

A: 

That key switches between the input mode between numbers and letters (modes "1", "a", "A", or "P" - where "P" stands for "Phone").

Q: 

Key Assignment

A: 

Our SDK provides functions to modify the key assignment, e.g. to make country-specific settings. For that purpose you can call the method "SysSetUserDefineKey" from within your own application.

Q: 

Screen Lock

A: 

You can unlock the screen by pressing the dedicated button on the screen or the "*" on the keyboard. You can reach the "*" on the keyboard by pressing the key for the decimal pointer while in phone input mode (please refer to the input modes mentioned above).
