BAL - potentiometer for adjustment of anti-locality - minimization of crosstalk between the panel's microphone and
its loudspeaker. It should not be moved without clear need, as its correct adjustment in installation conditions may
not be possible. The optimal position is located near the middle of the range of the "BAL" potentiometer
MIC - adjustment of gain on the channel: panel microphone -> uniphones line. Its adjustment can only be useful in
video systems. In other cases, its location should remain in the middle of the range. The volume in the uniphone
headphones is made by the appropriate potentiometer on the uniphone board.
SPK - regulation of sound intensity in the panel speaker. The principle is that the volume should be sufficient for
intelligible voice communication. Setting the volume too high can result in unexpected feedback and interjections.

ONNECTION OF UNIPHONES AND VIDEO DISTRIBUTORS
CC-4000 control electronics works with all digital uniphones from CYFRAL, i.e. SMART-D and MAC-D. All
uniphones are connected in parallel to L + and L- terminals. Connecting other uniphones or a uniphone of another
company may block the operation of the entry system.
The correct voltage prevailing on the line of uniphones during idle mode is 9-10V. During a call 4.5-5.5V. Other
voltages suggest incorrect operation.
In the Video system, connect the DV-4 signal distributor to the CC-4000 PCB. It is connected with four wires to the
terminals LINE "L +" "L-" "VH" "VL". It is necessary to remember that addresses programmed in distributors
cannot be repeated. In addition, the "H" "L" video cables must be terminated on the last distributor line.
In order to facilitate the installation of uniphones, use the "Installation mode" program, its detailed description can
be found in the manual for the CC4000 system.

ERIAL NUMBER
Each CC-4000 board is identified in the CC4000 entry system via a unique 6-digit serial number starting with digit:
6xxxxx. The pre-defined paper code table, constituting a factory table, is assigned to this number. The serial
number is located on the circuit board and as a sticker on the EEPROM memory. If the number on the stickers is
illegible, you can use the GC-2000 programmer. Knowledge of the serial number of the control electronics is
necessary to assign it to the panel during programming. It is not possible to change it.
