The numeric keypad functions like a standard 10-key pad. Simply press the desired number or operator keys to input data into your applications.

5.2. Dual Mode Num Lock

The FGK21C features a dual-mode Num Lock function. This means the Num Lock key on the keypad operates independently of your main keyboard's Num Lock. This allows you to use the numeric keypad for number input while your main keyboard's Num Lock is off, or vice-versa.

  • Націсніце Num Lock / Clear key once to activate or deactivate the numeric input mode.
  • When Num Lock is active, the numeric keys (0-9) will input numbers.
  • When Num Lock is inactive, the keys will function as navigation keys (e.g., Home, End, Pg Up, Pg Dn, Insert, Delete) as indicated by the secondary legends on the keycaps.
