If the green LED starts flashing now, there is a data transmission problem.
If there is no reaction, there is a hardware problem in the sensor head (f. i. pump, sensor, gas
generator, battery).
Now push button T to initiate a new self test. If SF goes off, the system is now ready again. If SF
 stays on, the sensor head must be checked with the diagnostic box.
