How to reach us:
The installation of article 70399 wireless converter has changed because of an necessary technical modification. The manuals of charge 177896 and 177897 show an old version.
The charge is shown at the back of the product:
An appliance in your neighbourhood possibly transmits on the same frequency. Please change the frequency setting of the appliance (see operating manual „changing the frequency“).
HX wireless transmitters with the article numbers 70392 and 70393 are also suitable for call system extension (= suitable for connection to an existing doorbell system).
No, because they is interference between them via the battery.
A separate operating manual is enclosed in the packaging of all products of the HX wireless series. The instruction for all other products is on the inside of the cardboard (please fold open).
Alternatively all information is available for download on our homepage.
Yes, because the power needed for playing the melody is supplied by a battery (batteries). (This does not apply to Model 70501 Croma.)
Make sure the bridge circuit between connecting clamps 0 and 1 is closed. (see connection diagram).
Unfortunately the connection is not possible.
Wait at least 16 minutes when setting the frequencies of different sets to avoid frequency interferences.
In this case you have to change the connector in the HX wireless transmitter / converter from B+C to A+C. the B+C variation causes an unwanted short circuit when using a chime with inductor.
