Despite an extensive pretesting program by Suunto and by independent divers all over the world, Suunto test program has found a software bug in the first series of Suunto Vytecs (products with serial numbers 205000-223700). It has been discovered that using Vytec´s SIMPLAN function may cause problems.
Although diving without using the SIMPLAN function does not cause problems and all features of the instrument work then normally, Suunto wishes that all users contact their local dealer, which contact information you can find here at www.suunto.com or Suunto HQ tel. +358-9-875870 to have their unit replaced with a new unit. Please note that the transmitter unit has no problems and is not to be replaced.
