Wireless Call Buttons are notoriously difficult to pair. However, most problems are caused by a handful of common problems.
Too Far Apart During Pairing
Move the button under investigation near to the receiver and repeat the steps outlined in the pairing section above. Note most receivers need to be within a short distance e.g. a meter or two when pairing up a new wireless call button even though the range of working can be much further.
Interference From Nearby Devices
Switch off any Wi-Fi routers, cordless phones, etc as they can cause interference. Ofcom (Regulator for Wireless in UK) explains how short-range wireless devices are regulated in the UK in case of problems in crowded frequency bands. Switch off temporarily while attempting to pair up Call Buttons.
Receiver Has Reached Its Button Limit
A Receiver has a limited amount of Pairings that it can store. Normally a Receiver can hold anywhere between 20 to 50 Pairings. If a Receiver has reached its limit of Pairings, new Wireless Call Buttons will not register at all.
Flat or Loose Battery
A low battery can get partially through the pairing of a wireless call button and then drop connection. This could be solved by fitting a new battery for the call button and ensuring it is seated correctly in the button.
Wrong Pairing Sequence or Timing
In most cases, Wireless Call Buttons will register during a pairing sequence, even when all of the parameters have not been set correctly. However, when the correct sequence of presses hasn’t been followed, the system will fail silently, without any error message being generated.
