7.5 Meaning of Indicators
7.5.1 Intensity lock
If you do not adjust the intensities for 10 seconds, the intensities are automatically locked to avoid accidental intensity
modification. When the intensity lock is on, the lock symbol appears next to the intensity displays. To unlock the intensities,
press either of the Intensity Decrease
buttons. You can then re-adjust the intensity.
7.5.2 Sequence indicator
The sequence indicator is the set of three chevron symbols on the upper middle of the screen. These symbols indicate when
the program is in warm up (first chevron), treatment (second chevron), and cool down (third chevron) modes. Each chevron is
filled as that portion of therapy occurs. For TENS (P3) and Edema (P4) treatments, there is only one sequence.
7.5.3 Work/rest indicator
The work/rest indicator is the curved line on the upper right of the screen. When the treatment is active, this indicator will
show whether the therapy is in "work mode" (contraction) or "rest mode" (low frequency stimulation). During the "work
mode", the upper line of the symbol will blink. During the "rest mode", the lower part of the symbol will blink. TENS (P3) and
Edema (P4) treatments do not have a rest mode.
7.5.4 Timer indication
The timer indicates the remaining time of the active sequence. For the TENS program (P3), the timer indicator displays
—: —
as the program duration is unlimited, and does not automatically shut off after a set time. (To end a TENS program, press the
ON/OFF
button twice.)
7.5.5 Low battery indicator
When the battery voltage drops below a predefined limit, the battery symbol appears.
If you are in the middle of a treatment, you may complete your treatment and change the batteries
before starting a new treatment. Don't start a new treatment without changing the batteries if the low
battery symbol is present. Please refer to section 7.3.1 for proper battery replacement.
7.5.6 Open circuit icon
The Open Circuit icon appears when the resistance between the device and the skin is too high. The
symbol appears next to the channel bar graph where the open circuit has been detected.
The Open Circuit icon might appear due to a poor electrode attachment or an interrupted electric
circuit. When the electric circuit is interrupted, the intensity drops to 0 and the program is paused. In
this case check whether the electrode lead wire is correctly connected to the device and whether the
electrodes are properly connected.
