Situational Awareness
Your Descent device can be used with the Varia Vision
™
device,
Varia
™
smart bike lights, and rearview radar to improve
situational awareness. See the owner's manual for your Varia
device for more information.
NOTE:
You may need to update the Descent software before
pairing Varia devices (
Updating the Software Using Garmin
).
Foot Pod
Your device is compatible with the foot pod. You can use the
foot pod to record pace and distance instead of using GPS when
you are training indoors or when your GPS signal is weak. The
foot pod is on standby and ready to send data (like the heart
rate monitor).
After 30 minutes of inactivity, the foot pod powers off to
conserve the battery. When the battery is low, a message
appears on your device. Approximately five hours of battery life
remain.
Improving Foot Pod Calibration
Before you can calibrate your device, you must acquire GPS
signals and pair your device with the foot pod (
).
The foot pod is self-calibrating, but you can improve the
accuracy of the speed and distance data with a few outdoor runs
using GPS.
1
Stand outside for 5 minutes with a clear view of the sky.
2
Start a running activity.
3
Run on a track without stopping for 10 minutes.
4
Stop your activity, and save it.
Based on the recorded data, the foot pod calibration value
changes, if necessary. You should not need to calibrate the
foot pod again unless your running style changes.
Calibrating Your Foot Pod Manually
Before you can calibrate your device, you must pair your device
with the foot pod sensor (
).
Manual calibration is recommended if you know your calibration
factor. If you have calibrated a foot pod with another Garmin
product, you may know your calibration factor.

• Decrease the calibration factor if your distance is too high.
Setting Foot Pod Speed and Distance
Before you can customize the foot pod speed and distance, you
must pair your device with the foot pod sensor (
).
You can set your device to calculate speed and distance using
your foot pod data instead of GPS data.

tempe
The tempe is an ANT+ wireless temperature sensor. You can
attach the sensor to a secure strap or loop where it is exposed
to ambient air, and therefore, provides a consistent source of
accurate temperature data. You must pair the tempe with your
device to display temperature data from the tempe.
