Getting started
1. Remove the casing of the battery compartment at
the back of the bell unit. Insert 3 pieces of 1.5V bat-
teries, type AA, according to the polarity indicated
at the bottom of the battery compartment. Put the
battery compartment casing back. Do not combine
new and old batteries or different types of batteries
(alkali, carbon-zinc and nickel-cadmium), do not use
rechargeable batteries!
2. Remove the back casing of the pushbutton through
the hole in the side of the casing with a screwdriver.
Insert 1 pc of 12V battery, type 23A according to the
polarity indicated. Reassemble the pushbutton cas-
ing.
3. Press the pushbutton of the bell (transmitter) to sound
the bell. A red LED diode will indicate that radio signal
was transmitted and that the pushbutton is matched
with the bell.
4. To match other pushbuttons, repeat the procedure
according to point 3.
5. Pushbuttons can be matched within 25 seconds after
inserting the battery.
6. If you want to match other pushbuttons later, proceed
according to point 1,2,3.
7. You can match a maximum of 8 buttons this way.
8. The broadcast range is 100 m in free space and
without electromagnetic interference. This range
may be affected by local conditions, e.g. the number
of walls the signal passes through, metal doorframes
and other elements, which affect the radio signal

transmission (presence of other radio appliances
operating on a similar wavelength such as wireless
thermometers, gate controllers etc.). The broadcast
range may decrease rapidly due to these factors.
9. The home bell (receiver) is designed for permanent
installation indoor or you can use it as a portable
"pager".
Note:
If you match another pushbutton (9th and more),
the memory of the first pushbuttons will be erased
automatically in reverse order.

Pushbutton installation
1. Before you start mounting, make sure that the door-
bell works properly on the place you have chosen.
2. Remove the back casing of the pushbutton through
the hole in the side of the casing with a screwdriver.
3. Place this back casing outside your home. Use double
side sticker or screws to fix it on the wall. Although
the pushbutton is waterproof, it is better to place it
under the shelter.
4. Reassemble the pushbutton casing.
5. Press the button, signaling LED on the pushbutton
indicates that radio signal was transmitted. Bell unit
sounds chosen melody.
6. If the signaling LED does not light, battery is flat,
please replace it. Battery usually last for one year but
it may differ according to conditions.
Note: The pushbutton unit can be placed on wooden or
brick walls, however, do not place it on metal surfaces
or surfaces containing metal. It might affect the correct
function of the unit.
