Batteries must be fresh and properly loaded before start operation.
4.1 Keypad operations
The 8300 Series Terminals have two keyboard layouts: 24 rubber keys and 39 rubber keys. The
functions of some special keys are as follows:
SCAN
Scan a barcode .
Press this button will trigger the scanner to read a barcode if the scanner port is
enabled.
ENTER Enter
.
There are two enter keys on the side of the scan key. Normally the enter keys are
used for command execution or input confirmation.
ESC Escape .
Usually this key is used to stop and exit current operation.
BS Back Space .
If this key is being pressed down longer than one second, a clear code will be
sent.
ALPHA /
α
The toggle key for Alphabet / Numeral input .
When the system is in alpha-mode, a small icon will be shown on the display. For
the 24-key keyboard, each numeral key can be used to generate one of the three
capital letters. For example, numeral
2 can be used to produce A , B or C . Pressing
the same key twice within one second, will call the letter B. Pressing the same
key without halting longer than one second, will cause the three letters to be
shown in a circulating way. Only when stop pressing the key for longer than one
second or pressing another key, will the system send the real key code to the
application program. Pressing the “Alpha” key again, lower case letter can be
inputted.
FN The function key .
This key cannot be activated alone, it must be pressed with one numeral key at
the same time. For example,
FN + 1 generates function # 1 , FN + 2 generates
function # 2 , etc (up to 9 functions). Also, this key can be combined with the
UP/DOWN arrow keys to adjust the contrast of the LCD. And when this key is
combined with the ENTER key, it will turn ON/OFF the backlight.
POWER Power On/Off .
To prevent a faulty push, it needs about 1.5 sec continuous pressing to turn
On/Off the power.
4.2 Application mode
This is the default operation mode when turning on the power. The operation depends on the
application module. Please refer to section 4.4.
