At each one of these intersections is where you'll need to pulse 1-3 times. On the belly I would recommend only pulsing once at each location so as not to negatively affect the good digestive bacteria inside the intestines. Keep box at least 1 foot away from you while it's turned on to prevent high frequency electro-magnetic field exposure. When using on the bed be aware that it will magnetize the bed springs. This will insure that the bedsprings will be magnetized to emit north pole energy into anyone lying on it which will be beneficial.
Magnetic media includes cassettes, computer disks, plastic cards with magnetic strips, etc.
Don't keep Pulser switched on when not using because the flash tube has a limited lifespan. Control the heavy cloth covered coil by handling it and not the wire. The connection there is prone to breaking if bent or pulled too much. It is not covered by the warranty because if left on continually it could burn out within a few days.
