If the nationally-used macere cannot display sleep record or no caller’s name. Please contact me online to get different versions of mecare

1: After download mecare APP, pls be sure to set the correct User info in Mecare app (Age, sex, Height, Weight),When measuring, if quit or can’t measure on the bracelet . Please change the skin color on app

2. When you open the MeCare app on your phone you need to scroll down the screen to see all of the menu options.

3. The ECG is initiated from the MeCare app on your phone (not from the KAIHAI H66). Have a finger pressed to the contact on the side of the KAIHAI H66 and then start the ECG from the MeCare app. The ECG should then start scrolling across the screen in the MeCare app. If the ECG is not showing a good reading try adjusting how your finger is pressed to the contact on the side of the KAIHAI H66, also try pressing down gently on the KAIHAI H66 to improve the connection of the two contact points underneath (against your wrist) or setting restore the factory settings on the APP

The reason that the phone cannot connect the bracelet . there are the following points
1:Mobele version is determined 4.4 or above . Ios 8.0 or above
2:wherher the mobile phone is a lot of garbage ,need to clean up
3:some android phones need to open the phone GPS
4: whether connected to many other devices on the Bluetooth . needs to be deleted
5:restart your phone and bracelet
6: Delete the device at Bluetooth . then lon in APP to reconnect
7:Whether the bracelet is connected to other mobile phones. (If connected, Bluetooth appears on the bracelet screen)

    The bracelet is excellent, the pressure shows exactly, they ordered mom as a gift. The box came crumpled, but inside the bracelet is packed firmly, came intact. In Nizhny Novgorod waited exactly a month.

    The order came quickly. All as in the picture. Pressure, pulse all accurate (error of several units 3-5)

    Nice bracelet. He arrived quickly and corresponds to what he bought. When I try, I’ll expand information.

  4. 5 out of 5

    Excellent view, good packaging as in the store, charged, the accuracy did not check, the convenience of the charge on the amateur, on one side is very convenient: you can always insert into the USB and charge, on the other hand, it is not very comfortable to remove the strap (it seems like it’s about to break). Delivery is fast, the goods met expectations. Chose from 10-20 different brands, did not regret.

    Ordered 24.05 shipping to Russia 16.06. received 30.06. Pressure measures very well. Through the mecare app, data is synchronized in the phone

  6. 5 out of 5

    It’s fine. I’m going to write down if the pressure is correctly measured.

  7. 5 out of 5

    The application for the smartphone is better with the instructions not to swing as it gives a link not to it.

    This is my second purchase. The first clock served 2 years. The clock still worked, but the charging place broke, this is their weak place. Wears their mom, the pressure measures often, day and night, first time checked with the tonometer, then she stopped. For Hypertonics is an excellent option, anywhere and at any time you can check yourself. It shows true values. Mom is very pleased, so they bought them the second time. The parcel went long, especially as it crossed our border. The store is average. Several times she wrote to him, specified the track number, answered, but everything was boring. Coincidence or not, but after my messages, the clock immediately started movement around the country))), before that, 2 weeks in one place were.

    The watch went a long, and a half months. And I think if I hadn’t started writing to the store, I might have waited as much. The watch was very liked, stylish, on the hands sit perfectly. Before synchronization with the phone, the pressure shows accurately, after synchronization it is necessary to play with the settings (age, pressure, etc.) then the measurements are very accurate. The seller is good, answers questions within a few hours. Watch recommend, 5 *****
