Monitor usage
After a call from the doorphone at the gate, a calling signal will be indicated
in the monitor and, at the same time, the image from the camera situated at the
entrance will appear on the screen. Using the monitor, conversation can be led with
a simultaneous observation of a calling person on the screen and electro - catch
at the entrance can be controlled. Digital doorphone CD-3100 co-operates with
various models of monitors. Detailed instruction of connection, programming and
operation differs depending on the model and is being attached individually to each
monitor.

Using coded lock function
To each apartment one four digit number is attributed which is preliminarily
defined in the entry phone production process. This code can be changed by an
installing specialist or occupant (unless this option is blocked). Door opening with
lock code is as follows:
Enter from the keyboard the number of apartment and confirm by a key KEY
Enter four digit code.
After having given the correct code the electro-catch will be released. In the uni-
phone in an apartment whose code was used to open the door three short acoustic
signals will be generated to inform the occupants that somebody has used their
code. Each failed attempt to enter the code is signaled with two long signals in
a uniphone receiver. Occupant can change the coded lock code that was given to
him. Changing method is described below.

Using electric keys
To unblock the entrance with iButton (DALLAS) key it should be put to the
reader in a video entry phone. Entry phone will read the key serial number and will
compare it with the numbers in the memory. If the read number corresponds to
one of the programmed numbers, the entry phone opens the electro-catch signaling
the opening of door with four short sound signals. Occupant can add register next
electronic keys (see next item of this instruction). The user can register keys only at
the entrance leading to his apartment. Keys for the main entrance can be registered
by an installing specialist only.
