MOUNTING INSTRUCTION MANUAL
1. General description
The bell may be used as a doorbell, an internal calling device or a personal
alarm device. The doorbell installation is not needed. The bell is 230 V AC
operated (connected directly to 230 V AC socket outlet), and the transmit-
ter is battery operated. 433 MHz frequency is used for signal transmitting
and receiving. The bell operating range reaches approx. 100 meters in
open area. There are 52 melodies and 4 sound levels to select.
2. Remote control registration
The remote control is factory adjusted to operate with the bell (a set) and
therefore no bell / remote control setting is required.
3. Selection of the melody and the operating mode
In order to select the bell sound/melody it is necessary to push a button
placed on the bell casing left side. Every button pressing causes the me-
lody/sound change. In order to change the sound volume (4 levels) it is
necessary to push button.
* The operating range given above, concerns the open area under ideal conditions, with
no obstacles. If there are obstacles between the receiver and the transmitter, one should
expect a decrease in the operating range for, respectively: wood and plaster by 5 to 20%,
brick by 20 to 40%, reinforced concrete by 40 to 80%. It is not recommended to use the
radio systems in case of metal obstacles, due to a significant limitation of the operating
range. Also aerial and underground power engineering lines of a large power capacity
and GSM transmitters in close proximity of these devices have a negative impact on their
operating range.
