Understanding the MI-CW074 Merkury Smart Doorbell Battery Status

Overview

This article is intended to help customers accurately determine the battery status of their MI-CW074 Merkury Smart Doorbell. One common source of confusion is the doorbell's behavior when it is out of battery.

Key Points

1. Chime Behavior When Out of Battery:

   • Even if the doorbell is out of battery, ringing the doorbell will still cause the chime to sound.
   • This can be misleading, as the chime sounding might make you think the doorbell is still powered on.

2. How to Verify the Doorbell is Powered On:

   • To confirm whether the doorbell has power, press the doorbell button.
   • Indicator Light: If the doorbell button lights up, the device is powered on.
   • No Light: If the button does not light up, the doorbell is out of battery.

Step-by-Step Guide to Check Doorbell Power Status

1. Press the Doorbell Button:

   • Approach your Merkury Smart Doorbell and press the button as if you were ringing it.

2. Observe the Button Light:

   • Light On: The doorbell is powered and functioning correctly.
   • No Light: The doorbell is out of battery and needs to be recharged.
