SUUNTO t4 - Manual (Page 48)

NOTE Even though both the Suunto t4 and the transmitter belt are water-resistant,
the radio signal does not carry in water, which makes the communication
between Suunto t4 and the transmitter belt impossible.
7.3. Replacing the battery
Your Suunto t4 operates on a 3-Volt lithium cell, type: CR 2032. The life expectancy is approximately
12 months of operation with an average of 4 hours of training a week. The higher your average
amount of training hours a week, the shorter the battery's life expectancy will be. Your Suunto t4
will display the symbol
when the battery starts running low.
NOTE To reduce the risk of fire or burns, do not crush, puncture or dispose of
used batteries in fire or water. Only replace them with manufacturer-spe-
cified batteries. Recycle or dispose of used batteries properly.
7.3.1. Replacing the battery of the Suunto t4
To replace the battery:
1. Use a coin to open the battery compartment on the back of your device. Ensure that the O
ring and all surfaces are clean and dry.
2. Remove the old battery.
3. Place the new battery into the battery compartment with the positive side facing up.
4. Slide the battery gently against the contact plate on the side, ensuring that it does not break
or bend out of place.
5. When replacing the cover, rotate it carefully counter-clockwise with your thumb in order to
align the threads. The cover should rotate easily at first without having to use force. If you
have to use force right at the start, the threads are misaligned and may be damaged.
