HOW DO I POWER ON MY SMARTWATCH?
Press and hold down the middle power button for at least three seconds.
Make sure the smartwatch is charged before trying to power it on. The
smartwatch will also power on when connected to the charger.
HOW FAR AWAY CAN MY SMARTWATCH BE FROM MY
PHONE AND STILL BE CONNECTED?
The range of the wireless Bluetooth connection between your phone
and your smartwatch can vary greatly depending on the environment.
In general, you should have at least 10 metres (or 30 feet) of connectivity.
IS MY SMARTWATCH WATER AND/OR DUST PROOF?
Your smartwatch is dust and splash resistant with a waterproof rating of
IP68. However, we recommend limiting exposure to dust and water
because certain materials on the smartwatch (such as leather straps) may
react poorly to exposure.
WHY CAN‘T I PAIR MY SMARTWATCH TO MY PHONE?
Ensure that your smartwatch is powered on and Bluetooth is enabled on
your phone. Launch the App and follow the on-screen instructions for
pairing your watch. If it fails to connect, check the Bluetooth menu on your
phone. If you see the smartwatch in the device list, remove it. Relaunch the
App and repeat the pairing process.
