Uni Com doorbell frequency change

[CiderMonkey]

I have a Uni Com Wireless doorbell, the kind you can record 10 seconds of your own song to have as a doorbell chime.
It keeps going off without anyone pressing it so I need to change the frequency but have lost the instructions!
There are 4 small blocks in the back of the button which i know is something to do with this, but can't remember what to do - can anyone help??

we had the same prob with a similar type of bell. basically someone else in our street had the same bell on the same frequency as us....I though it was kids playing knock down ginger!!

you just need to alter the frequency on the actual bell and the chimer. in your case I think you need to change the 'peg' style things in the back of the bell and the chimer if you have this type of bell.

hope it helps.

goonerbird - yes, I know I need to change the frequency and that it it something to do with those blocks in the back..but what I need to know is what do I have to do to them?

Hi
Did u find out how 2 do this as I have the same problem!! Think its something to do with taking the black pegs 1-4 out??

Thanks

Just take out some of the small blocks - you can take out 1, 2, 3 or all 4. There are 16 ways in total so it's very unlikely that if you take out a random set that they will match your neighbour's frequency.

I have just carried out a couple of experiments on my set of Uni-Com wireless door bells and figured out a successful process:

- Take the doorbell switch unit off its clip frame to expose a bank of 'jumpers' labelled 1-4.

- Remove one or more of the plastic jumpers to reveal two pins. I removed just jumper number 4, but you can take them all away, leave just one, two or three in your choice of position. Each permutation sets the system to transmit at one of 16 frequencies.

- Next, take the chime unit and take the battery cover from the back.

- Remove one of the batteries

- Hold down the doorbell switch (on my model it is a grey button) whilst slotting in the removed battery. The chime unit scans for transmitting frequencies when it powers up. After about 30 secs of holding the button down (I am not certain of exactly the time required, but 30 secs worked for both of my units) release the button.

- Pressing the button again should make the doorbell chime unit ring with your chosen ring tone. If it doesn't, click the button marked 'S' on the doorbell switch unit until your chosen ring tone sounds.

- You are good to put the switch unit back on its clip frame next to your door!

The Uni-Com model that I have is found under the following link:

Here is the small print:
- I only have one model of Uni-Com wireless doorbell chime and the above instructions worked perfectly for it. I have two switch units and two chime units and they now both chime on a different trigger frequency.
- It worked for me, you may or may not have different mileage for you model, whether it is the same as mine or not
- I offer no guarantees about anything a

had same problem with phantom chimes going off (knew it wasnt someone at door as played a different chime) have just followed Dream Ravens posting and changed set to a different frequency by removing 3rd and 4th pegs in bell push while battery removed from chimes and then pressed bellpush while replacing battery
