SUUNTO t3 - Manual (Page 32)

• If you have been using the belt for some time, the battery may need changing. For instructions
on how to change the transmitter belt's battery, see Section 7.4.2. Replacing the battery of the
heart rate belt.
3.3. Heart rate limit settings
In the Heart Rate Limit menu, you can set the heart rate limits on or off, define the upper and lower
limits, and set the heart rate alarm on or off. You can set the heart rate limits to help you stay
within a defined heart rate range, which you can set to match the goal of your training.
While training, your real-time heart rate can be displayed in the center of the screen. If the average
heart rate shortcut is selected, your real-time average heart rate of the entire log at that point is
displayed in the bottom row as either beats per minute or a percentage of your maximum heart
rate. In the Settings menu, you can set alarms to notify you when you go above your set upper
heart rate or below the set lower heart rate.
When you have reached the set HR limit, the alarm turns on. If you don't lower the HR within 4
minutes, the alarm turns off automatically.

heart rate
Lower limit
When the Limit alarm is on, Suunto t3
gives you an alarm when your heart
rate rises above the upper limit or
drops below the lower limit. The alarm
continues for 4 minutes until you return
to your target heart rate range.
Upper limit
By checking your average heart rate you can adjust your training intensity to make sure the session
is as effective as possible.
