I have a wireless doorbell made by DESA International, INC. I believe the model number is SL-6195-RX. FCC#: BJ4-61WDB95RX. There is another number on the unit: 390-6195-04. I need the push button part that holds the battery. The battery terminal inside has broken off. Any help would be appreciated. Thanks. Dane

It seems your doorbell transmitter got wet and corroded the contacts.
These push buttons are not sealed at all and thus will let rain, snow etc. eventually corrode the electronics.
Solution: Find a new push button on eBay.


Cheers

Heath-Zenith (I beleive they bought DESA) makes a battery remote push button bell that says its compatible with all Heath Zenith chimes. I bought one at Home Depot and it worked for my SL-6195-RX. (an on line doorbell seller and the Home Depot assoc all said it wouldn't work.)
UPC is 16963961975.
Item also shows a code "11G43" on a sticker on the back of the package.

The contacts in the outside push button unit may need cleaning. They do get dirty over time. If that doesn't solve your problem you can contact the Zenith Company, who is now is the manufacturer for tech service issues. 800-858-8501.

Hope this helps solve your problem.

I just solved a similar problem with mine. I found a PDF of the instructions for changing the frequency and the tone: http://heath-zenith.hcents.com/data/manuals/598-1034-02.pdf

Batteries are located in the doorbell push button case in the back. Slide open a compartment to reveal the batteries.

Check that the dipswitches on the button and the reciever doorbell unit match. Also verify that your battery is not installed the wrong way.

Open up both the button and the main unit and switch the codes with the pins. It done on a row of pin sets - Default is usually connectors on 5-6-7 (8 is on the main bell unit and causes the ding-**** to change to a Westminster chime).
With a pair of needle nose pliers pull the connector and set them on different numbers. You must do this on both pieces, When you have a unique code its no longer an issue with the neighbors.

I believe this is also the Zenith door chime. I bought mine at home depot, and they have the push buttons.
