Features

Notable features.

PUSH-keys

The terminal has eight PUSH-keys, providing (by use of SHIFT) sixteen functions. PUSH, Programmable Utility for String Handling, allows the user (or the host computer) to program often used words or code sequences that can be transitted by pushing the appropriate PUSH-key. The strings associated with PUSH-keys are stored in non-volatile memory and are not lost when power is turned off.

Character limits

Each PUSH key has a limit to how many characters it can store. The limits are:

  • P1 to P8: 12 characters
  • P9 to P12: 32 characters
  • P13 to P16: 48 characters

Language versions

The terminal exists in several versions (different local language): Danish, English, French, German, international, Norwegian and Swedish.
