The integrated keypad on DC1 devices and the (optional) 
external DX-KEY-LED keypad feature a six-digit 7-segment 
LED display.
The optional DX-KEY-OLED keypad is a multi-language cleartext 
display unit (OLED = Organic light-emitting diode). It can be 
used in conjunction with DC1 variable frequency drives. 
The buttons on both keypads work the exact same way.
The additional Hand and Auto buttons on the DX-KEY-OLED 
keypad do not do anything in this case.
→
On OLED displays, languages can be selected by pressing 
START +  simultaneously.
Display: Select Language.
The display language can be changed with the  and  arrow 
keys. The selected language setting can then be saved by 
pressing the OK button.

If you want to use the START and STOP buttons to control the 
DC1 variable frequency drive, the corresponding setting needs 
to be enabled in parameter P-12 (“Local process data source”) 
regardless of which keypad type or model is being used 
(integrated DX-KEY-LED or external DX-KEY-OLED).
