The key tones for ID decoding and ID code memory are programmed in register 016 for all
decoders.
The first 7 digits of register 016 contains the tone sequence that has to be decoded for the ID code
memory. Arbitrary digits are coded with F, as well as the digits that are not in use.
In register 086 the ID code memory is configured.
The first digit activates/deactivates the update function. If update is activated and an ID code from
the memory is decoded the old ID is deleted and the new one is stored in the respective position.
The second digit activates/deactivates the FIFO mode (first in - first out). In FIFO mode the ID code
that arrived first (i.e. the oldest one) is displayed.
In the third digit it can be defined if an arriving ID code is displayed immediately or if it is to appear
only after skimming to its position.
Storing of ID codes from double sequences is done according to the decoder programming. The ID
mode defines in which of 2 tone sequences the ID code is transmitted. It is then passed to the ID
code memory.
Example: 6-tone sequence 123x5x with 2-digit ID code in digits 4 and 6:
Register 016 123F5FFF

Muting (register 018) is triggered by the first two tones and lasts until the end of the tone sequence.
The first tone must be a valid tone in terms of duration. As soon as the second tone is recognized,
handpiece and loudspeaker are muted. For digits that are programmed with ‘F‘, all tones are valid.
To disable muting ‚EE‘ is programmed.
