system. During the entire treatment period, the MOU
continues to monitor system operation. It detects whether:
• sufficient gel is present on the transducer surface,
• the internal battery has reached a low battery condition,
• the device is operating properly.
If an alarm occurs, do not turn the device off. The
MOU display indicates the type of problem by
displaying a message on the LCD display along with
an audible tone. The following alarm displays may
occur during system operation.
1. Add Gel
A blinking addition (+) symbol with an audio tone
means you need to add gel to the transducer face.
This display will last for 30 seconds after which the
device turns “off.”
Correct this condition as follows:
1. Remove the transducer from the RAF Strap Assembly.
2. Add gel to the transducer surface. Avoid overloading
with gel.
3. Re-insert the transducer and snap on cap making
sure it properly snaps in place.
If the problem has been corrected within 30 seconds
of the alarm, the blinking symbol will turn off and the
treatment countdown will continue. If the problem is
corrected after 30 seconds have passed, the device
will turn “Off.” It will be necessary to press the
“On/Off” button to turn the device back “On” for a
new, complete 20-minute treatment period.
