Notes:
1. Terminology and test conditions are according to IEC standard IEC60679-1, unless otherwise stated
2. Oven supply VS1 can be switched on and off separately, while oscillator supply VS2 is on.
Oven will not work properly without VS1 applied !
3. In accordance with mentioned clauses of Cospas/Sarsat Specification C/S T.001
