* 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.
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 installa-
tion is not needed. The bell is 230 V AC operated (con-
nected directly to 230 V AC socket) and the bell push-
button 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 36 melodies and 4 sound levels to select. A LED indi-
cator signals the bell ringing too.
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 at the front of the bell casing. Every
button pressing causes the melody/sound change. The
bell volume change (8 stages) by pr or – push-
buttons at the front of the bell casing.
