• Reduce the backlight timeout (Changing the Backlight Settings, page 35). • Reduce the backlight brightness. • Turn off Bluetooth wireless technology when you are not using connected features (Bluetooth Connected Features, page 20). • When pausing your activity for a longer period of time, use the Resume Later option (Stopping an Activity, page 2). • Turn off activity tracking (Turning Off Activity Tracking, page 10). • 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 34). • Limit the smartphone notifications the device displays (Managing Notifications, page 20). • Stop broadcasting heart rate data to paired Garmin devices (Broadcasting Heart Rate Data to Garmin® Devices, page 11). • Turn off wrist-based heart rate monitoring (Turning Off the Wrist-based Heart Rate Monitor, page 11). NOTE: Wrist-based heart rate monitoring is used to calculate vigorous intensity minutes and calories burned. • Turn off the pulse oximeter feature (Turning Off the Wristbased Heart Rate Monitor, page 11). • Use UltraTrac GPS mode for your activity (UltraTrac, page 33). • Select the Smart recording interval (System Settings, page 35). 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. How can I manually pair ANT+ sensors? You can use the device settings to manually pair ANT+ sensors. The first time you connect a sensor to your device using ANT+ wireless technology, you must pair the device and sensor. After they are paired, the device connects to the sensor automatically when you start an activity and the sensor is active and within range. 1 Stay 10 m (33 ft.) away from other ANT+ sensors while pairing. 2 If you are pairing a heart rate monitor, put on the heart rate monitor. The heart rate monitor does not send or receive data until you put it on. 3 Hold . 4 Select Settings > Sensors & Accessories > Add New. 5 Select an option: • Select Search All. • Select your sensor type. After the sensor is paired with your device, a message appears. Sensor data appears in the data page loop or a custom data field. Can I use my Bluetooth sensor with my watch? The device is compatible with some Bluetooth sensors. The first time you connect a sensor to your Garmin device, you must pair the device and sensor. After they are paired, the device connects to the sensor automatically when you start an activity and the sensor is active and within range. 1 Hold . 2 Select Settings > Sensors & Accessories > Add New. 3 Select an option: • Select Search All. • Select your sensor type. You can customize the optional data fields (Customizing the Data Screens, page 31). My music cuts out or my headphones do not stay connected When using a Forerunner device connected to headphones using Bluetooth technology, the signal is strongest when there is a direct line of sight between the device and the antenna on the headphones. • If the signal passes through your body, you may experience signal loss or your headphones may become disconnected. • It is recommended to wear your headphones with the antenna on the same side of your body as your Forerunner device. • Since headphones vary by model, you can try moving the watch to your other wrist.
