I am new to x10 and just bought my first switch, remote, and receiver to try it out.  Great news is that it worked.  However, when using the remote the transceiver makes a "popping" sound that is rather loud.  This sound is annoying.  Is there something set up wrong or something I could do to reduce it?

The Remote Transceiver Module is Model RR501 and the remote palm handheld is HR12A.

Any help is appreciated.

The transceiver is an appliance module set to either house code 1 or 9, and the sound you hear is the relay turning it on.

You probably have it set to the same house code as your switch.

Relay modules tend to click.   It's the physical sound of the relay changing states.

If your RR501 is on say housecode A,  set the wall switch to A2 - A16.  (see the manual)

If you plug something into the RR501, you can control it with A1 and hear the click.
Anything on the powerline at A1 will turn on also.

If you want plugin modules without the click, use lamp modules.   

Appliance = Relay = Click

Some relay modules are quiet but they will say so on the advertising as it's a selling point.

Acutally, I didn't realize this was even an appliance transceiver.  This is was came in the package from homecontrols.com.  There isn't much of a manual with it, so let me ask another question:  What does it mean for code 1 or 9?  And yes, I did have the palm switch on the same house code as the transceiver.  Once I changed that, the sound seemed to stop.

Thank you for your help.

HouseCode refers to the 16 Letters from A to P
UnitCode refers the the 16 numbers 1 to 16

The RR501 can be set to any housecode, and it will transmit
any signal received from a transmitter on that housecode
onto the powerline.  From unit code 1 to 16.

Let's say you set the housecode to A.

Then the RR501's will act as a appliance module, either
responding to A1 or A9  ie 1(or 9).   But it will send any
code from A1 to A16 onto the powerline for any module
listening to a code in that range.

A bonus automation module... gotta like that.   

As vhoang said, there are 16 house codes and 16 unit codes per house code, for a total of 256 device addresses. Transceivers like the RR501 use just the one house code and can control up to 16 devices.

As you expand, you can add more transceivers set to different house codes, or use ActiveHomePro which is an all house code transceiver (can control all 16 house codes, that is all 256 individual addresses). Not to mention software to control your automation. 

Have fun.

Thank you for all your help.  I think I now understand the product and system better.
