The device must send and receive several messages, which
takes longer than sending a single message during regular
use.

Iridium Satellite Network

Your device requires a clear view of the sky to transmit messages and track points over the Iridium satellite network. Without a clear view of the sky, your device attempts to send the information until it acquires satellite signals.
TIP: For the best connection with satellites, attach the device to a backpack or to your upper body.

inReach Features

To get the most out of your device, you should activate it. Activating the device allows you to use inReach features including messaging, SOS, and LiveTrack.

Messages

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.
Tips for Pairing ANT+ Accessories with Your Garmin Device
• Verify that the ANT+ accessory is compatible with your Garmin device.
• Before you pair the ANT+ accessory with your Garmin device, move 10 m (33 ft.) away from other ANT+ accessories.
• Bring the Garmin device within range 3 m (10 ft.) of the ANT+ accessory.
• After you pair the first time, your Garmin device automatically recognizes the ANT+ accessory each time it is activated. This process occurs automatically when you turn on the Garmin device and only takes a few seconds when the accessories are activated and functioning correctly.
• When paired, your Garmin device receives data from only your accessory, and you can go near other accessories.

Troubleshooting

Restarting the Device

If the device stops responding, you may need to restart it. This does not erase any of your data or settings.
Hold the power button for approximately 30 seconds.

About Heart Rate Zones

Many athletes use heart rate zones to measure and increase their cardiovascular strength and improve their level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted heart rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are calculated based on percentages of your maximum heart rate.

Fitness Goals

Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying these principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve cardiovascular capacity and strength.
If you know your maximum heart rate, you can use the table (Heart Rate Zone Calculations, page 19) to determine the best heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms and health centers can provide a test that measures maximum heart rate. The default maximum heart rate is 220 minus your age.

Heart Rate Zone Calculations

Zone % of
Maximum Heart Rate
1 50–60% Relaxed, easy pace,
2 60–70% Comfortable pace,
3 70–80% Moderate pace, more
4 80–90% Fast pace and a bit
5 90–100% Sprinting pace,
Perceived Exertion Benefits
rhythmic breathing
slightly deeper breathing, conversation possible
difficult to hold conversation
uncomfortable, breathing forceful
unsustainable for long period of time, labored breathing
Beginning-level aerobic training, reduces stress
Basic cardiovascular training, good recovery pace
Improved aerobic capacity, optimal cardiovascular training
Improved anaerobic capacity and threshold, improved speed
Anaerobic and muscular endurance, increased power
