User Manual

Model: M520+F55

Installation

Choose a location that is not near a heat source or on something that moves (like a door). For non-mounting locations, choose a place where the doorbell will be easy to see and hear.

For Receiver:

Plug-in receiver: Just plug the receiver into a standard outlet in the room.

For Push Button:

IMPORTANT: Before installation, please test if the operating range you choose is working and set music if needed.

Before you drill any hole in the wall, please make sure there are not cables or pipes.

To install, you will require a drill and cross-headed screwdriver.

Content:

Content will vary according to your kit.

The push button supplied with this kit is pre-programmed to operate with the doorbell. If it is not, see "Connect a Push Button" on page 5.

Safety:

Before proceeding with the installation, please note the following safety warnings:

What You Should Know Before Installation:

  1. Test the operating range you desire. Choose an electric outlet at the height of 3.3 feet at least and plug in the receiver and take the button outside the door to test if it can work well within the range you have chosen.
  2. Set a desired music (different or same one) for transmitters before installation. For music setting, see Operating Instructions. Doorbells have been paired and set to a default chime (Ding Dong) before leaving the factory.
  3. Please do not install the transmitter on metal doors since it is hard for the signal to transmit.
  4. Please take out the battery insulating strip before using. (As picture 1) [battery-insulation-strip-removed]
  5. Ensure all surfaces are clean by wiping the installation area with a clean cloth. Please note that the sticker will have poor adhesion if you attach it to a dirty or uneven surface. Sunlight or rain will also affect the adhesion over a longer period of time.
