13. Modes of Operation
13.1. ON MODE
To turn the device ‘ON’ press and hold the Power Button for at least 1 second. Press
the Toggle Button on the right side of the sam Power Controller to set the treatment
duration. The treatment duration may be set for 1, 2, 3 or 4 hours. The battery indicator
LED and treatment timer LED will be displayed on the control panel (see section 8: LED
Display). The applicator indicator LED will be displayed on each attached applicator
(See Figure 2, page 10). Each connected applicator will emit ultrasound energy
immediately upon the sam Power Controller entering the ‘ON’ mode of operation. A
powered sam Applicator will always emit ultrasonic energy unless it enters the sam
Sensing Mode or the treatment duration concludes.
13.2. OFF MODE
When the device is ‘OFF’, the LEDs on the applicator will not be illuminated, the LEDs
on the sam Power Controller will not be illuminated, and no ultrasound energy will
emanate from the device. Always turn the device ‘OFF’ when not in use or if pain or
uncomfortable heating is indicated by the patient.
13.3. SAM SENSING MODE
In the event that the treatment site underneath the applicator reaches the temperature
threshold, the applicator will pause ultrasound output and vibrate once with a red LED
notification to signify that the device has begun a cooling or rest cycle. sam Applicator
will automatically resume treatment with a blue LED notification after the site
has cooled.
Warning: Should the patient ever report discomfort or a painful sensation from the site
under the sam Applicator, the applicator should be removed immediately.
Caution: At no time during treatment should the applicator be covered by thick
insulating material such as a coat, blanket or sports wrap. This may cause
sam to disable and remain disabled throughout the therapy session.
13.4. END OF TREATMENT MODE
At the end of treatment, an amber-colored “Treatment Complete” LED will illuminate
on the sam Power Controller and all other displays (battery indicator, treatment timer,
indicator LED, and applicator LEDs) will be inactive. All ultrasound emissions from
the applicator will cease. The “Treatment Complete” LED will remain illuminated for
approximately 8 hours after completion of therapy, at which point it will time out and
turn off. To set the sam Device for a new treatment, assess whether the sam Device
requires recharging.
