Operation and programming manual
It is possible to change a series of panel operation parameters (individual and general) in a simple and
intuitive way. Parameters can be changed both by a fitter and user. Range of changes to be performed in the
digital panel depends on the codes. Access to all functions is protected with a fitter password. Access to
functions directly related to only one flat is user password protected. To provide proper maintenance of the
system, fitter can limit the access of regular users to some or all functions.

Keyboard
Depending on the operation mode, to which the digital panel is switched, the keyboard and its keys fulfil
different functions.
During normal operation, having depressed the key „
” the screen displays ring symbol. Using "#", we can
delete the entered symbols or interrupt the last operation.
When in menu
Settings
keys „7”, „8”, „9” and „0” operate as arrows: left, up, right, down and keys identified
with „
” and „#” confirm or cancel the selection.
Figures 7, 8 present keyboard and functions of keys in the mentioned modes of operation.

Initial start-up
After correct electrical connection, the panel (initially calibrated in factory) is ready to use. Should any
problems exist concerning operation of audio line, set two potentiometers in the back of the panel
(Loudness - adjusts the loudness of audible signal in the panel, Microphone - adjusts amplification of
acoustic signal from the panel towards handset, illustration 9), so that at the maximum possible loudness of
the panel and maximum amplification of acoustic signal gathered by microphones, no coupling exists. The
simplest way to perform this procedure is setting the required loudness and amplification of microphone, at
which no excitation in the panel speaker occurs.
Balance potentiometer is factory set in optimum position
and it is recommended not to adjust it.
