OM265EN issue 16

Treatment using rigid capacitive electrodes
Attach the 5 cm or 10 cm capacitive electrodes to the arms and
secure in place by tightening the retaining sleeve. Connect the
electrode plugs to the output sockets on the Megapulse Senior 265
rear panel. Ensure that the electrode cables are kept apart from each
other using the cable retaining clips on the electrode arms.
Position the electrodes using the Megapulse arms so that the radio-
frequency electric field from the electrodes will pass through the
treatment site. Tighten the handwheels to prevent movement.
Make sure that the electrode type selected is the same as those
being used. To start treatment, turn the rotary control clockwise.
If the treatment time is zero, the unit will give a short alarm to
indicate that the output cannot be energised.
If the treatment time is not zero, the output of the Megapulse will be
energised. Once tuned (if necessary) the treatment icon will flash in
the bottom right window of the screen and the treatment time will
begin to count down. Advance the output control to the required level
- in continuous mode this is normally when the patient can feel
warmth from the treatment. The presence of output from the
electrodes may be verified using the fluorescent output tester which
will light when placed near the electrodes.
The Megapulse Senior 265 has automatic tuning in order to optimise
power transfer to the patient. While the unit is tuning, the treatment
timer will not count down, and a rotating tuning icon will appear in the
bottom right window of the display. Should the unit be unable to tune
to the load provided by the electrodes after 45 seconds an alarm will
sound and an error message appear. Turn off the output power using
the rotary control, reposition the electrodes and try again. When the
treatment time reaches zero, the shortwave energy from the
electrodes is terminated, the output display will show 0% and a three
second alarm is sounded.
