Improving GPS Satellite Reception
• Frequently sync the device to your Garmin account:
◦ Connect your device to a computer using the USB cable and the Garmin Express application.
◦ Sync your device to the Garmin Dive app using your Bluetooth enabled smartphone.
◦ Connect your device to your Garmin account using a Wi‑Fi wireless network.
While connected to your Garmin account, the device downloads several days of satellite data, allowing it to
quickly locate satellite signals.
• Take your device outside to an open area away from tall buildings and trees.
• Remain stationary for a few minutes.
The temperature reading is not accurate
Your body temperature affects the temperature reading for the internal temperature sensor. To get the most
accurate temperature reading, you should remove the watch from your wrist and wait 20 to 30 minutes.
You can also use an optional tempe external temperature sensor to view accurate ambient temperature
readings while wearing the watch.
Maximizing the Battery Life
You can do several things to extend the life of the battery.
• Change the power mode during an activity (Changing the Power Mode, page 24).
• Turn on the battery saver feature from the controls menu (Viewing the Controls Menu, page 3).
• Reduce the backlight timeout (Changing the Backlight Settings, page 115).
• Reduce the backlight brightness.
• Use UltraTrac GPS mode for your activity (UltraTrac, page 103).
• Turn off Bluetooth technology when you are not using connected features (Connected Features, page 41).
• When pausing your activity for a longer period of time, use the resume later option (Stopping an Activity,
page 26).
• Turn off activity tracking (Turning Off Activity Tracking, page 73).
• Use a watch face that is not updated every second.
For example, use a watch face without a second hand (Customizing the Watch Face, page 109).
• Limit the smartphone notifications the device displays (Managing Notifications, page 43).
• Stop broadcasting heart rate data to paired Garmin devices (Broadcasting Heart Rate Data to Garmin Devices,
page 54).
• Turn off wrist-based heart rate monitoring (Turning Off the Wrist-based Heart Rate Monitor, page 54).
NOTE: Wrist-based heart rate monitoring is used to calculate vigorous intensity minutes and calories burned.
• Turn on manual pulse oximeter readings (Turning Off Automatic Pulse Oximeter Readings, page 69).
