 FOR THE MANAGER-1-A410/A420  02.4.20 6:48 PM  Page 17

You can program alphanumeric characters for departments, PLUs, functions and so on in the character entry
mode. 
There are two ways for programming characters: using character keys on the keyboard and entering character
codes with numeric keys on the keyboard.

Enter a character according to the position in the programming keyboard layout.

To enter a character, simply press a corresponding character key.
To enter a numeric character, press 

key and enter a number by ten keys (0 – 9).

[Ex.]  Entering the character “135” :     

➞ 135 ➞

To enter a space, press 

/

key. 

Î

: This key toggles the double-size character mode and normal-size character mode. The default is the

normal-size character mode. The double-size character is displayed with the letter “=” (ex. =S). 

[Ex.]  To program the name “SHARP” in double size :     

Î

➞ SHARP ➞

Î

Ó

: You can enter a lower-case letter by using this key. Press 

Ó

key just before you enter the lower-case

letter. This key also allows you to enter the characters/symbols shown at the upper right of keys. 

[Ex.]  To program the name “Sharp” :     

➞ S ➞

Ó

➞ harp ➞
