15.2. MAGNET MODE
When the magnet is applied:
 antiarrhythmia functions are inhibited (detection of rhythm
disturbances, charging, and therapy),
 pacing amplitude is set to 6 V,
 pulse width is set to maximum,
 pacing rate is set to the magnet rate,
 the following functions are disabled: Smoothing, Rate Response.
When the magnet is removed:
 the sensor rate is forced to the basic rate,
 arrhythmia detection algorithms and sequential therapies are
reinitialized,
 therapies start with the least aggressive program for each area.
The other parameters remain at their programmed value.
The magnet rate values are as follow:

15.3. RESPONSE IN THE PRESENCE OF
INTERFERENCE
If the defibrillator senses electrical noise at a frequency above 16 Hz, it
switches to an asynchronous mode at the basic rate. The programmed
mode is restored as soon as the noise is no longer detected.
Ventricular pacing is also inhibited by ventricular noise. It can be
restored by setting the parameter V pacing on noise to Yes.
