5. Operations 
Batteries must be fresh and properly loaded before start operation. 
5.1 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. 
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. 
5.2 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.
