Charging the Watch

Before using your watch, you need to charge its battery using the USB charging clip and either the optional AC adapter or a computer with a USB port capable of charging external devices.

It takes approximately 2.5 to 3.5 hours to fully charge your watch, depending on your charging method.

Charge your watch in an environment with a temperature from 41 to 95 °F (5 to 35 °C).
Note: If you charge your watch in an environment outside the required temperature range, you see this screen on your watch:


  1. Attach the USB charging clip to your watch as shown below. The charging clip should fit into the groove at the back of your watch.


    Caution:
    Do not attach the USB charging clip to your watch if either the clip or your watch are wet or dirty. This may cause corrosion, communication failures, or other problems.
  2. Connect the USB charging clip to one of the following devices:
    • AC adapter: Connect the USB charging clip to the USB port on the optional AC adapter and plug the AC adapter into an electrical outlet.


      Caution:
      Only use the optional AC adapter that is compatible with your product to charge your watch, or the watch may not charge or operate correctly.
    • Computer: Connect the USB charging clip to a USB port on your computer that is capable of charging external devices.


      Note: USB charging from a computer port may not work with all computers. Do not connect the USB charging clip to a USB hub or other intermediate device.
    Charging begins and you see a screen displaying the battery level on your watch.


    If you connected your watch to a computer where you have already installed the Epson View Uploader software, the software starts automatically on your computer. Close the software window as necessary.
  3. When charging is complete and the watch screen shows the battery level at 100%, you can open the clip fully and disconnect the USB charging clip from your watch.


    Note: If you continue to charge the watch after the battery level reaches 100%, the watch engages an overcharge prevention feature to protect your watch.
  4. Disconnect the USB cable from the AC adapter or your computer, and unplug the AC adapter if you used it. If this is the first time you have charged your watch, you see the Language screen:


  5. Press the  Up or  Down button to select your language and press the  Enter button. You see the Settings screen:


  6. Configure your watch using one of the available methods.
