Water resistance, Changing the strap length

5.2. Water resistance

Your Suunto t1 is water resistant up to 30m/100ft and the transmitter belt to 20m/66ft according to ISO 2281 standard (www.iso.ch). This means that you can use your Suunto t1 for swimming and other water sports activities but you must not use it for scuba diving or freediving.

To maintain water resistance and to ensure that the warranty remains valid, we strongly recommend that you have all service, except for battery change, performed by authorized Suunto service personnel.

NOTE	Never push the buttons while swimming or in contact with water. Pressing
	the buttons while the unit is submerged could cause the unit to malfunction.
NOTE	Even though both the Suunto t1 and the transmitter belt are water-resistant,
	the radio signal does not carry in water, which makes the communication
	between Suunto t1 and the transmitter belt impossible.

5.3. Changing the strap length

The strap length of some Suunto t1 models can be adjusted for a perfect fit. Follow the steps below:

•Remove the buckle by releasing the spring bars with a pin, paper clip or other sharp object.

•Remove both spring bars from the pin holes.

•Shorten the strap by cutting along the grooves on the inner surface. You can do this for instance with scissors. If you are unsure of the correct length, cut the pieces one by one and test the length after cutting each piece. Cut in turns from both sides of the strap to keep the sides equally long. Be careful not to shorten the strap too much.

•Replace the spring bars into the last pin holes of both sides of the strap.
