The
Stop!
button is used to stop the clock. This reduces the clock's electrical
current requirement to a minimum and is useful when the video matrix or the CPU
card will be out of operation for an extended period. This feature prevents
premature battery discharge and the ensuing loss of settings.
With SIMATRIX NEO V2 this function is no longer necessary, as the real time clock
needs much less battery, if the SIMATRIX is switched off.

Summer time
option, the system clock is set an hour earlier at the change-over point and the
status changes to winter time.
The reverse applies in the case of winter time.
