Important Information Regarding
Function Buttons
The LED’s of the functions buttons are updated by transmitting DTMF tones, which are
within a audible range (similar when interrogating an answering machine).
Please note that some devices are trying to suppress or even eliminate these tones during
the time of transmission.
In default the LED’s of the function buttons will always be updated, even if the phone is
being used.
The status update of the LED’s during a telephone conversation can be disabled by using
TK-Suite! An LED update will then be carried out as soon as the call has ended.
Alternatively you may set the updating of Function Button LED’s as described below:
