What You Should Know Before Installation

Doorbell’s radio frequency signal can be affected by metal, walls, installation height, and interference signals from other device. SadoTech expandable doorbells can work within 600 feet range depending on the specific using environment.

  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; take the button outside the door to test if it can work well within the range you have chosen.
  2. Set a desired music/chime (different or same one) for transmitters before installation. For music/chime setting, see Operating Instructions. Doorbells have been paired and set to a default chime (Ding Dong) before leaving factory.
  3. Please do not install transmitter on metal doors since it is hard for the signal to transmit.
  4. Please do not install transmitter too close to ground, which will affect the operation range.
  5. Please install transmitters in the right way up, see product structure diagram on page 7.
  6. Operating range will become shorter and blue indicator turns less light if battery in transmitter is at low power status. Battery type is 12V 23A alkaline battery.

Operating Instructions

Volume Adjustment
There are 4 levels of volume for choosing. Find the Volume Control Button on left side of receiver. Press this button repeatedly to get desired volume level.

Music/Chimes Selection

There are 52 choices of music/chimes. Use Music Control Button on receiver to cycle through the different music/chimes.To set and activate the chosen or desired music/chimes, follow step 3.

Pairing Transmitters and Setting Music/ Chime

  • Select a desired music/chime for one transmitter by pressing the Music Control Button on receiver. (Refer to step 2)
  • Set Receiver into learning mode (pairing mode) by pressing the Volume Control Button on receiver for 5 seconds . Then you will hear a “pairing alert chirp” and see fast  CONTINUOUS LED flashing on the  receiver–this will indicate the pairing ready status.
  • Next, quickly trigger the pairing process within 5 seconds (see Note1) by pressing transmitter push button. You will hear the music/chime you selected, which means that your operation is completed successfully.

Note 1
 You must trigger the transmitter within 5 seconds after entering  learning mode since receiver will exit the mode automatically without getting signal from transmitter after 5s has passed.

For Pairing Additional Transmitters
Just repeat Step 3a-3b-3c for each additional transmitter.

Note 2

Pair and set only one transmitter at a time to avoid interference and ensure successful operation. Different or the same music/chime can be set for multiple transmitters.

For Pairing Additional Sensors
Receiver also can work with other sensors. Our system supports up to 30 Transmitter or Sensor combinations. Repeat Step 3a-3b-3c to add more Sensors. But the methods to trigger and set the pairing process differ for each type of sensor:

Door sensor
 Separate the two parts of door sensor to trigger and set the pairing process until you see the indicator light up and hear the tune you selected. (Battery type: 1* AA battery)

Motion sensor
After entering learning mode, switch it on quickly; when indicators light up, wave your hand quickly in front of the sensor to trigger and set pairing process until you hear the tune you selected. ( Time interval between 2 detections is 5 seconds. Battery type: 2 *AAA batteries)

Reset (Clearing out Settings)
To clear out all settings, press the Music Control Button for 5 seconds, you will hear a” pairing alert chirp” and see a SINGLE quick flash, then the music/chime of receiver will turn into the default one (Ding Dong) and pairing will be unset and cleared. You can trigger and press a transmitter to verify the unsetting.

Installation Methods

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

Receivers Installation

  • Plug-in receiver: Just plug receiver into standard outlet in room, then it will work. Please choose music/chime or make pairing first if you want to add more transmitters.
  • Battery-type receiver: Put in three 1.5 AAA batteries, then you can choose whether to hang it up or just put it on desk.

Frequently Asked Questions

Can I use other doorbell buttons with the receiver?

Yes, you can use Starpoint series doorbell buttons.

Can I use the receiver with other SadoTech products?

Yes, you can use it with SadoTech wireless doorbells, wireless sensors and wireless switches.

How do I pair the transmitter and receiver?

Please refer to the user manual for detailed instructions.

How long does the battery last?

The battery can last up to 2 years depending on usage.

What is the range of this product?

The range is up to 1000 feet in open area. It may be affected by walls and other factors.

How frequently should the battery be changed on average?

The waterproof transmitter uses a 12V 23A alkaline battery as its power source. If the push button is hit 10 times every day, it can be utilised for six months. –

Any distance is ideal, right?

They are expected to function up to 1,000 feet away. One of mine has a push button and a ringer separated by around 500 feet, and it still functions well!

Could I buy multiple of these and utilise them in a house (multi family) without them confusing one another? This may seem like a simple inquiry.

Yes, each set of waterproof SadoTech Model C has an own frequency to prevent interference. Each receiver and transmitter has a code series sticker. Only components with the same code can cooperate. To identify between different sets, you can purchase several sets in white or black and place a note inside the glass cover at the bottom of the transmitters. The SadoTech model C waterproof, however, cannot be expanded.

Will the chosen sound play constantly if I hold down the doorbell button till I let go of it? Consider the sound of the “school bell.”

The button doesn’t emit a single, continuous sound if you hold it down. However, if you keep holding it down, it will keep making the short bell noises until you release.

Can a different ring be used with a second transmitter?

It is conceivable, yes. You can configure a second transmitter to have a different ringtone by adding one.

How is the button installed?

Simple to instal Simply bolt the receiver to an exterior wall and plug it into an electrical socket.

Can a new button be purchased?

It appears that you can just buy an extra button if you browse down the page and look at it.

Does this require an electrical outlet? Or could it all be powered by batteries?

Yes, this model’s receiver needs to be plugged in. There is no set kit that comes with just 1 battery-operated receiver and 1 waterproof button. However, if you don’t mind the white hue, you can purchase them separately and pair them to operate together.

Can you set a timer using the doorbell?

No, you cannot set a timer using the doorbell.

How can you tell how much battery is still in it?

When the battery is low, the blue LED dims.

Can a lithium battery be used?

Lithium batteries are not compatible.
