Make sure a soundhead is rmly plugged into the device before turning the device ON. When changing to a dierent size
soundhead, turn the machine o rst, remove the soundhead, plug in the desired soundhead, then turn the machine on
again. Please acquaint yourself with the following terms and device features prior to delivering an Ultrasound treatment.
Soundhead Warming
Soundhead Warming is an optional feature used to maintain a comfortable soundhead temperature for the patient. When
Soundhead Warming is ON, the soundhead should remain in its holder as a small amount of Ultrasound output is emitted
from the soundhead (0.1 W/cm
2
). e soundhead warming mode is automatically stopped during a treatment, and resumes
automatically as needed aer a treatment has ended. Although the Soundhead Warming feature defaults to OFF, it can be
turned ON at any time by going to the Setting Screen and pressing the WARMING key.
Coupling
e term “coupling” refers to the ability to deliver ultrasonic waves from the soundhead to the skin surface with as little
impedance or dissipation of power as possible. Coupling (contact between the soundhead and the treatment site) may be
provided by a coupling agent such as a gel or lotion. Any material used as a coupling agent must be highly conductive of
ultrasonic waves. Air is a very poor conductor of ultrasonic waves. Holding the soundhead in the air while a treatment is
running may also damage the soundhead crystal and/or stress electronic components in the device.
If any part of the soundhead is exposed to air during the treatment, coupling is decreased. e air bubbles in a whirlpool, for
example, can decrease the eective Ultrasound therapy to the patient. Avoid allowing any air between the soundhead and
the treatment area. Water is an excellent conductor of ultrasonic waves; therefore, underwater treatments provide excellent
coupling.
During any Ultrasound treatment the soundhead should be moved continuously, covering an area approximately 2-4 times
larger than the size of the soundhead. e full surface of the soundhead should maintain contact with the patient’s skin
(except with underwater treatments).
CAUTION
• Do not drop the soundhead on hard surfaces.
• Do not cool the soundhead with ice water or ice packs.
• Do not allow the soundhead to overheat repeatedly.
• Do not hold the soundhead in the air while a treatment is running.
All of these conditions are likely to damage the soundhead crystal and/or to stress electronic components in the
device. Damage caused by these conditions is not covered by warranty.
