* 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 installation is not needed. The
bell and the pushbutton are battery operated. 433 MHz frequency is
used for signal transmitting and receiving. Operating range reaches
approx. 100 meters in open area. A single bell may be operated with
two remote controls, and a single remote control may operate the
unlimited number of bells. There are 36 melodies to select. The bell
also has the ringing optical signalling, useful for hearing-impaired
people or people with little children (it is possible to turn the sound
off completely). The bell may operate in 3 operating modes – sound
only, sound and optical signalling, optical signalling only.
2. Remote control registration
In order to save a first remote control to the bell memory it is ne-
cessary, after inserting a battery into the bell battery compartment,
to push and release the remote control call pushbutton. The remote
control entry is acknowledged with the bell sound. In order to save
the successive remote control to the same bell memory it is neces-
sary: first, to push and release programming pushbutton placed on
the bell casing, and then to push and release the remote control
pushbutton. It is possible to save up to 4 remote controls to a single
bell memory.
3. Selection of the melody and the operating mode
In order to select the bell sound/melody it is necessary to push me-
lody pushbutton placed at the back of the bell casing. Every button
pressing causes the melody/sound change. The sound volume (3
stages) may be adjusted with the use of pushbutton. The operating
mode may be set with the use of slider: – sound only, the slider in
the left position – optical signalling only, the slider in the mid position
– sound and optical signalling – the slider in the right position.
