    What will I receive in a SadoTech doorbell kit?

    The exact components of your kit will depend on which model you have purchased. However, most kits will include a button or sensor, a chime and a battery. They will also include anchors, screws and self-adhesive tape for easy install.

    Are SadoTech doorbells weatherproof and/or waterproof?

    All of our buttons are weatherproof. Two of our models, the Classic and the Starpoint Set, have 100% waterproof buttons available as purchase options. The Touch Pet model is also 100% waterproof. We recommend placing weatherproof doorbell buttons underneath an awning or a canopy, while 100% waterproof buttons can remain uncovered.

    What is the frequency of a SadoTech doorbell unit?

    Our units use radio frequency at 433 MHZ.

    What are the product dimensions?

    Most of our doorbell buttons are 1.6” x 2.8” x .6” and most of our chimes are 3.1” x 3.1” x 1.1”.

    What is the operating range for the doorbells?

    SadoTech doorbells have a range of at least 500 feet. They can operate at up to 1000 ft. in an open area.

    How may different chime tones are there?

    There are 52 different tones available for the chime.

    Will the chimes tones play randomly each time the button is pressed?

    No, you can choose which tune you would like it to play.

    Can the button or sensor penetrate through walls?

    The signal range can penetrate walls and doors, so you shouldn’t have any problems.

    Installation and Set Up


    How do I install the button or sensor?

    Buttons or sensors can be installed either with double-sided tape or anchors and screws. For more detailed instructions, please see Manuals and Instruction. [link blue text to manuals and instruction]

    How do I install the chime unit?

    SadoTech's chimes are very easy to install: All you have to do is just plug it into a 110-volt wall outlet. No batteries are required for plug in chimes.

    How do you control the volume on the chime?

    There are four volume levels, from 25db to 110db. Find the volume control button on the left side of the chime. Press this button repeatedly, until you reach your desired volume level.

    What type of battery does the the button/sensor use?

    The button requires a single A23 type battery, which is included in in your doorbell kit.

    How long does the button battery work under normal usage conditions?

    Basic doorbell batteries should last for 6 months, assuming they’re being pressed 10 times a day. Expandable doorbell batteries should for 4 months, also assuming 10 presses per day.

    Can you mount the button/sensor on a metal surface?

    Yes, though for optimal performance it’s better to place it on a non-metal surface.

    Is there an instructional video showing how to set up additional chimes, buttons or sensors for expandable doorbells?

    Yes, we have an instructional video posted here: https://youtu.be/24Y8aIUFepo

    Troubleshooting


    Why did the chime not sound when people walked by the sensor?

    This may have to do with the sensor’s delay settings. The sensor has two sensor delay modes. One setting is "with no delay" and the other has a 5-8 seconds delay in between motion triggers. This is to prevent constant alerting and ringing if a trigger occurs. Try changing the delay settings and see if that fixes the problem.

    The sensor worked during install, but seems to have stopped working shortly afterwards. What happened?

    This may be due to very frequent triggering of the sensor, which can deplete the battery quickly. Please try replacing the batteries for optimal performance.

    I have a motion sensor. Why does the chime randomly sound when no one is around?

    Be sure to place the sensor in an area where there are no random movements. Small animals and objects blowing in the wind cans ometimes cause false alerts.

    Does the transmitter have a tendency to allow signals from other wireless devices to ring the doorbell?

    No, this is a learning code doorbell and so it has randomly generated signals. They are very unlikely to conflict with other wireless devices.

    It appears one of my SadoTech basic doorbell buttons has gone bad. Can I buy just a replacement button?

    Unfortunately, you cannot replace just the button in the basic model, as every unit is programmed to a unique frequency.
