HOW TO CHANGE THE QUICK RELEASE STRAP
Suunto accessory straps with a quick release mechanism are easy to change without any additional tools. To detach a strap, pull the spring on the underside of the strap to release the pin and remove the strap. To attach a new strap, first insert the pin on the opposite end to the spring mechanism into its socket, then pull the spring and slip the other end into place. Release the spring and check that the pin goes all the way into the socket. You can also pull the strap gently to ensure the strap is in place.
