SUUNTO t1 - Manual (Page 15)

Whenever you enter Training mode or start the stopwatch, your Suunto t1 automatically searches
for signals from a heart rate belt. Once the device has found the signals, your heart rate will be
displayed in the center of the screen.
2.1.1. Heart rate signal troubleshooting
Although the heart rate transmitter belt can be used with gym equipment like treadmills and training
bikes, using the belt near overhead power lines or some magnetic or electronic devices may cause
interference with the belt's signal. If you can't see a heart rate signal, or lose the signal, try these
steps to fix the problem.
• Exit and then re-enter Training mode.
• Make sure that you are wearing the heart rate transmitter belt correctly. (See section 2.1.)
• Ensure that the electrode area on the back of the belt is slightly wet.
• Move away from any potential source of interference.
• 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 5.4.2.
2.2. Settings
Before you are able to make the most of your Suunto t1, it's worth taking some time to personalize
it to suit your individual needs. If you have already defined the settings based on the information
given in Section 1, you can skip to section 3.
To recap, this figure shows how to enter the Settings menu and its different items.
