5. Configuration of video lineDepending on the topology of video signal transmission system there are available threeset-ups of video line configurations. This is done by means of jumpers available in thecut- out in the rear part of monitor casing (see dwg. 2 or sticker on the monitor rear part(see dwg. 2 or sticker at the monitor rear part).- BNC set the jumper in this position if video signal is sent by a concentric cable.- UTP - set the jumper in this position if video signal is sent by UTP spiral cable.- UTP+TERMINATOR - set the jumper in this position if video signal is sent by UTP spiralcable and the monitor is located at the end of video bus bar or is the only line load.6. Monitor controlMonitor is equipped with smooth control of volume, colour saturation and picture brightnessas well as three step control of acoustic signals (calling from external panel, calling fromfloor panel, door bell).Conversation loudness can be changed by changing the position of potentiometer at themonitor lower part to receive the required loudness.Volume of acoustic signalization can be changed only if no connection is made. For thispurpose pushbutton LOCK should be pressed and held for a moment until LED1 or LED2is changed (approx. 2 sec). LED1 means loud signal, LED2 muffled and flashing LED2means switched off signalling (no possibility of making connection or monitoring). Nextlonger pressings of pushbutton LOCK result in sequential change of volume (loud, quiet,switched off) and state of signaling diode.Set volume level is kept in memory also after fading of monitor power supply.Note!In special cases audio signal can be corrected by means of the following potentiometersavailable after the monitor rear casing has been taken off:- BAL - correction of loudness level of a signal coming from external panel- MIC1 - correction of loudness level of a signal going to external panel- SPK2 - correction of loudness level of a signal coming from floor panelAfter removing of the monitor rear casing potentiometer MIC2 is accessible; it is used forthe correction of loudness level of a signal going to floor panel.In normal conditions satisfactory control is ensured by a potentiometer located in themonitor lower part (see dwg.1).7.
