Legal Disclaimer

The Proximity Care Button is reliant on the cellular phone Bluetooth coverage to work. The Bluetooth capability may vary between phone models, tablet models, service providers and environmental locations where usage may occur. The types of Bluetooth devices (including mobile phones & tablets) that can be connected to the Proximity Care Button are limited and, even among compliant devices; there are some which may not operate reliably with your Button. It is the responsibility of the consumer to purchase a suitable Bluetooth product that will operate correctly with the Proximity Care Button . 

Although Bluetooth is intended to be a standard protocol, Bluetooth® device manufacturers may incorporate certain changes within this standard protocol over the course of the product lifecycle of the device (especially mobile phones). These changes are outside the control of Mercari Limited and may result in the Bluetooth functionality becoming impaired. Proximity Care Button requires Bluetooth 4.0 or upwards in order to connect. 

The Proximity Care Button App requires a modern Smart Phone with IOS or Android 4.3 or above to be able to connect to the button. 

Distance Limitations

Most Bluetooth devices, especially those that run on battery power, are Class 2 Bluetooth devices. Class 2 devices have a range of about 10 meters, or around 30 feet. The range limitations are meant to avoid the quick depletion of the battery. While the Bluetooth signal will work through walls, the more objects that are in between the devices, the less overall range the devices will have. Class 1 Bluetooth devices have a range of about 100 meters, but the size and power consumption needed to create a Class 1 signal means that small wireless devices could not use it and are confined to the 10 meters of the Class 2 protocol.


Bluetooth devices work with the 2.4 GHz radio band, which is the same unlicensed frequency used by many other wireless devices. If many devices in the same area are all using the same stretch of bandwidth, it can lead to overall network problems, as the signals collide and information has to be resent. The Bluetooth signal was designed to change it’s frequency many times per second to reduce this interference, but if enough devices are trying to use the same small stretch of bandwidth, interference is inevitable. Bluetooth 3.0, being used in devices created in 2010, uses the 6-9 GHz spectrum, so it will have much fewer interference issues. Bluetooth 3.0 devices are also capable of transmitting at 2.4 GHz to communicate with earlier Bluetooth technologies. Bluetooth 3.0, running at 2.4 GHz, has the same issues with interference as earlier Bluetooth technologies.
