Introduction January 2000
1-4
The intensity can be adjusted step-less from about 5 to 150 watts and is shown on the LED
output power at the front panel meter to assist the operator.
The Radarmed 650 is suitable for use with the circular-field, through emitter and
longitudinal-field emitters.
Certain minimum distances from the surface of the body must be maintained with different
emitters.
- Circular-field emitter approx. 10 cm
- Longitudinal-field emitter approx. 5 cm
- Through emitter 0 cm
The required distance for the through emitter is determined by the internal design.
Circular-field emitter
The circular-field emitter can be used on restricted body areas to effect deeper penetration. It
is the most universal, and therefore the most used, emitter.
Longitudinal-field emitter
The longitudinal-field emitter is used to treat long parts of the body, such as limbs.
Through emitter
The through emitter is used to treat large areas. The special form of this emitter is well
adapted to the appropriate body contours. Restricted regions, such as the shoulder and knee
joints, can likewise be advantageously treated with this emitter, as can large muscular areas
such as the pectoral girdle. For reasons of hygiene, a cloth should always be placed
between the patient and emitter.
The Radarmed 650 has been designed and manufactured to ensure the highest level of
safety; the unit fully complies with the IEC 601-1 (general standard), IEC 601-2-6 (microwave
equipment) and IEC 601-1-2 (EMC) standards.
