of major discomfort. The Heatpad will feel hot during use. If a lower temperature is used, after
several uses, return to the "High" mode to see if the discomfort has been reduced.
11. CUFF SEALING
The "Sealing Cuff" message is displayed while the vacuum
motor runs. The bar along the bottom shows the vacuum
level; when the bar reaches the length of the Display Panel,
the full vacuum has been achieved.
IMPORTANT NOTE: The seal on the bottom of the Vacuum Chamber may have become
dislodged during shipping and unpacking. If the seal is not properly in place, the Vacuum
Chamber will not seal. Refer to the "Troubleshooting" section of this User Guide for simple ways
to correct this issue.
12. HAND PRESSURE INDICATOR (HPI)
When the unit seals properly, the top line of the display
will show the remaining therapy time and the temperature
level indicator. The bottom line of the display will show
the Hand Pressure Indicator (HPI). The HPI shows if you
have the right amount of hand pressure. You are in the
optimal zone when the double column indicator is near
the middle.
Too much pressure will set off an alarm (beep) and display
"Lift Hand Slightly".
Too little pressure will set off an alarm (beep) and display
"Push Hand Down Slightly". Keeping the HPI in the middle
will ensure ideal function.

An enlarged view of the bottom row of the Display Panel below shows the number of points that
are awarded per second. The number of points earned is based on the position of the HPI. More
points are scored by keeping the HPI in the center of the screen. If the "Lift Hand Slightly"
message or the "Push Hand Down Slightly" message are displayed, the user will hear an audio
beep, and 10,000 points are subtracted from the total score every second.
The highest number of points awarded is 60,000 points per minute. Therefore the user could
accumulate as many as 1,200,000 points in a 20-minute therapy session (more or less points
depending on the length of the session). A score of half the highest possible score (i.e. 600,000
for a 20-minute session) would indicate that the user did a very good job of keeping their hand
properly seated on the heat pad. The final score can also be used as a gauge of proper hand
position during unattended patient therapy sessions. The unit must be used for a minimum of 10
minutes in order to qualify for a high score.
At the end of the session the final score is shown, along with the current high score. If a new high
score was earned, this will be shown. Pressing the ✔ button changes the display to show a
random message. This message falls into one of three basic groups, that vary based on the
average points per second that was scored by the user. If the average points per second is high, a
"Great Job" message will be displayed. If the average points per second was in the middle
(acceptable but not "high"), a "Good Job" message will be displayed. If the average number of
points per second is low, a "Try Harder" message is displayed. These messages can be viewed at
the end of the session (along with the final score) to see how well the user did at keeping their
hand in the correct place on the hand pad during the therapy session.
"Great Job" messages:
"Major league performance! Wow" "Super! That's how it's done!"
"You got some serious skills!" "You did great!"
"Awesome Job!"
"Good Job" messages:
"Nice! beat this score next time!" "Well done, keep up the good work!"
"Next time get the high score!" "Steady hand - good job!"
"You did pretty good!"
"Try Harder" messages:
"I remember MY first time..." "Did you actually try?"
"Come on! Try harder!" "My grandma could do better!"
"Yay! You got the new low score!"
Pressing the ✔ button again causes the unit to turn off or go back into standby mode.

20. TROUBLESHOOTING AND FAQ
If you are having problems using the AVACEN device, review this section to see if a solution is
described. If you are still having trouble, call AVACEN Medical at (888) 4-AVACEN
(888-428-2236) and select "Customer Service" or email: Customer[email protected]. When
you call, have your AVACEN ready and make note of the device serial number (marked on the
bottom of the device).
A. How long should treatment last?
The AVACEN device is designed to comfortably and noninvasively provide dry heat therapy for a
period between 10 and 30 minutes. For many conditions 15 minutes twice daily is sufficient.
Treatment time and/or use frequency can be increased to accommodate professional
recommendations or absence of response to treatment. The best times for treatment are in the
early morning and prior to bed. Suggested use should be: 15 minutes first thing in the morning
using the LEFT hand (reminder hint: "Left is for day Light") and 15 minutes before bed using the
RIGHT hand (reminder hint: "Right is for Night"). Switching hands assumes both hands are equally
healthy. If not, use the healthy hand only.
Any level of major discomfort (after adjusting temperature) is not normal. Stop using the
AVACEN right away and report the problem to AVACEN at (888) 4-AVACEN (888-428-2236) and
select "Customer Service" or email: [email protected].
B. How important is the placement of my hand?
It is critical to make sure that the palm is completely inside the vacuum chamber and resting on
the Metal Heatpad. The raised, egg-shaped portion of the Heatpad should be cupped in the
center of the palm.
C. Is it necessary to wear the AVACEN Mitt?
The AVACEN device design requires a special Mitt. Without this mitt, the AVACEN may not seal
properly. Using the mitt also provides a sanitary environment for multiple family members or
clinic users. In addition, the Mitt keeps dirt and hand oils off of the critical metal Heatpad and
from inside the vacuum chamber. This prolongs the efficiency and extends the useful life of the
AVACEN.
D. Do I need a new a Mitt every time I have a treatment?
No. As long as the Mitt appears to be in good repair and clean, the same person may use it for
months.
E. Do I need to purchase the Mitts from AVACEN?
The AVACEN was developed and tested for FDA Clearance using a very specific Mitt material and
design. We have priced the Mitts to be very affordable and therefore recommend that Mitts be
purchased by contacting AVACEN at: [email protected]

F. The AVACEN unit powers down while the 'Sealing Cuff' message or 'Lost
Vacuum Seal' message is displayed
If the AVACEN is not able to reach the proper vacuum level
after 60 seconds, the "Unit Did Not Seal Properly" message
is displayed and the unit will automatically power down. If
vacuum is lost during a therapy session the "Unit Has Lost
Vacuum Seal" message is displayed and the unit will
automatically power down. This can occur if:
(i) The Inflatable Cuff is not properly sealed at the wrist.
- See Item P: "Checking the inflatable cuff for leaks"
(ii) A Mitt is not being used.
- Put on a Mitt.
(iii) The end of the Mitt does not extend beyond the sealed cuff.
- Pull the mitt on your hand and make sure the end of the mitt is outside the cuff.
(iv) The user's hand is not properly positioned.
-It is critical to make sure that the heel of the palm (where the palm connects to the wrist) is
completely inside the vacuum chamber and touching the palm end of the Metal Heatpad (closest
to opening).
(v) The Vacuum Chamber is not properly positioned.
- See section 23: " PERIODIC MAINTENANCE" for taking the Vacuum Chamber on and off.
If your skin is very dry, put a small amount of hand lotion on your wrist and rub it in to improve
sealing after your hand is placed into the mitt. If you are still having trouble, call AVACEN Medical
at (888) 4-AVACEN (888-428-2236) and select "Customer Service" or email:
[email protected].
G. "Rest Palm On Heatpad" message
To make sure the device calculates the proper pressure of your hand against the Metal Heatpad,
it is important during the initial sealing and calibration process that you apply slight pressure with
your palm against the Heatpad. Without this base pressure, the onboard computer will not be
able to properly measure the pressure of the palm against the Heatpad and "Rest Palm On
Heatpad" message will continue to appear for 30 seconds and the AVACEN will power down.
It is very important that the AVACEN is placed on a level surface and your hand is NOT inside the
Vacuum Chamber when you turn the unit on. If your hand is inside the vacuum chamber (resting
on the Heatpad) when the unit is turned on, the onboard computer will not measure your hand
pressure correctly. If you turn the unit off (by mistake or on purpose), remove your hand from
the Vacuum Chamber before turning the unit back on again.

H. "Calibration Failed" message
It is very important that the AVACEN is placed on a level
surface and your hand is NOT inside the Vacuum Chamber
when you turn the device on. If your hand is inside the
vacuum chamber (resting on the Heatpad) when the device
is turned on, the onboard computer will not measure your
hand pressure correctly. If you turn the device off (by
mistake or on purpose), remove your hand from the
Vacuum Chamber before turning the device back on again.
To make sure that the device computes the proper weight of your hand against the Metal
Heatpad it is important during the initial sealing and calibration process to apply slight pressure
with your palm against the Heatpad. Without this base pressure, the onboard computer will not
be able to properly manage the pressure of the palm against the Heatpad. At that point the
"Calibration Failed" message will appear and the device will shut down.
After the weight of the hand is measured during the calibration phase, the onboard computer
monitors if there is too much or too little palm pressure against the Heatpad. This will be
displayed on the Hand Pressure Indicator (HPI). After a number of uses, it will become much
easier to judge the proper pressure of your palm against the Heatpad. If you are still having
trouble, call AVACEN at (888) 4-AVACEN (888-428-2236) and select "Customer Service" or email:
[email protected].
I. "System Error" Message
The device is always checking and adjusting the
temperature of the Heatpad. If for some reason it can not
measure the Heatpad temperature, a warning message will
be displayed. This can happen for a few reasons:
(i) The device is very cold.
- Turn off the device and allow it to warm to room temperature before turning on.
(ii) The device has been stored somewhere very hot.
- This may have damaged the device. Unplug the unit, then plug back in and try again. If the
message is displayed a second time, call AVACEN at (888) 4-AVACEN (888-428-2236) and select
"Customer Service" or email: [email protected].
J. There is noise while the AVACEN device is running
There is an air pump inside the AVACEN that runs during therapy. Some motor noise is normal,
and the noise will vary as the AVACEN adjusts the air pressure of the inflatable cuff and inside the
vacuum chamber. This improves the comfort of the inflatable cuff.
K. The inflatable cuff is too tight
The inflatable wrist bladder is designed to work on almost any size wrist and therefore it may feel
tighter to some people than others. The first inflation exerts the most pressure to assure a proper
seal every time. This highest pressure will only last for less than a minute. After that the pressure
will relax to a more comfortable level. If the pressure does not relax there may be a vacuum leak.

L. I keep getting a "Push Hand Down Slightly" or "Lift Hand Slightly"
message
It is very important that the AVACEN is placed on a level surface and your hand is NOT inside the
Vacuum Chamber when you turn the device on. If your hand is inside the vacuum chamber
(resting on the Heatpad) when the device is turned on, the onboard computer will not measure
your hand pressure correctly. If you turn the device off (by mistake or on purpose), remove your
hand from the Vacuum Chamber before turning the device back on again.
To make sure that the device calculates the proper pressure of your hand against the Heatpad it
is important that during the initial sealing and calibration process that you apply slight pressure
with your palm against the Heatpad. Without this base pressure, the onboard computer will not
be able to properly manage the pressure of the palm against the Heatpad and "Push Hand Down
Slightly" or "Lift Hand Slightly" message will continue to appear along with a beeping sound.
During treatment there is a chance the heel of your palm will be pushing too hard against the
palm end of the Metal Heatpad (end nearest the wrist opening). This condition is not wanted and
will cause the "Lift Hand Slightly" message to appear along with a beeping sound. At this point
just retract your hand into the cuff to its original position and the alerts will stop. To make it
easier to shift your hand, briefly press in the pressure release button on the bottom of the cuff to
deflate the cuff slightly.
One of the top features of the device is to monitor and display too much or too little pressure of
the hand on the Metal Heatpad. Correct hand pressure on the Heatpad increases heat transfer.
After the weight of the hand is calculated during the calibration phase, the onboard computer is
responsible for monitoring the palm pressure. If there is too much or too little palm pressure
against the Heatpad, it will be displayed on the Hand Pressure Indicator (HPI). After a number of
uses, it will become much easier to judge the proper pressure of your palm against the Heatpad.
If you are still having trouble, call AVACEN at (888) 4-AVACEN (888-428-2236) and select
"Customer Service" or email: [email protected].
M. The AVACEN Heatpad is too hot (or too cool)
For the most benefit "High" is recommended. Select "Med" or "Low" only in the case of major
discomfort. The Heatpad will feel hot during use. If a lower temperature is used, return to the
"High" mode after several uses to determine if the discomfort has been reduced. If the heat does
not recede to a more comfortable level RIGHT AWAY stop using the device and call AVACEN
Medical at (888) 4-AVACEN (888-428-2236) and select "Customer Service" or email:
[email protected] After using the device for some time, you hand may get used to
the heatpad temperature, so that it does not "feel" as hot as it used to. This is normal and does
not mean there is a problem with the device.
N. The Heatpad seems "loose"
For proper measurement of hand weight on the heatpad, the heatpad must be free to move up
and down and side-to-side slightly. This is normal and does not mean there is a problem.

200226 AVACEN 100, AVACEN 100-E User Guide 15
O. The Display Panel Power LED does not illuminate after pushing the ON
Button
Make sure that the power cord is plugged into the unit and the light on the Power Supply (black
box between the device plug and wall plug) is on. If the light on the Power Supply is not on;
check the ends of the power cord to make sure it is plugged into both the Power Supply and the
wall plug. If the power Supply light is still not on, make sure that the wall plug is working
properly. Do this by plugging in another device or lamp that you know works into the wall plug. If
you are still having trouble, call AVACEN Medical at (888) 4-AVACEN (888-428-2236) and select
"Customer Service" or email: [email protected].
P. Checking the inflatable cuff for leaks
This test can be found in USER SETTINGS. Refer to section 21: "USER SETTINGS" in this Guide for
details on starting the test.
Q. Excessive swelling of the hand
The AVACEN device is designed to comfortably and noninvasively provide dry heat therapy. Any
level of major discomfort is not normal. Right away stop using the AVACEN and report the
problem to AVACEN Medical at (888) 4-AVACEN (888-428-2236) and select Customer Service.
R. Red or purple spots on the hand
Red or purple spots on the hand (usually the backside) after the first couple of AVACEN device
uses can be caused by a minor hemorrhage (petechia). These spots are harmless and will likely
vanish within a few days. Should they not disappear or if they are accompanied by any level of
major discomfort; this is not normal. Right away stop using the AVACEN and report the
problem to AVACEN Medical at (888) 4-AVACEN (888-428-2236) and select Customer Service.
S. Hand itches or tingles
It is common and normal for the hand to slightly itch or tingle during a treatment session as
circulation in the hand increases. If this at any time becomes uncomfortable or painful,
immediately stop the treatment session and call AVACEN Medical at (888) 4-AVACEN
(888-428-2236) and select Customer Service.
T. My hand is reddish-colored like it has been in hot water
This state is normal and you will likely see this on every treatment. It is due to the increased
microcirculation (blood in the capillaries).
U. Sweating when using the AVACEN
The AVACEN device is designed to comfortably and noninvasively provide heat therapy. Mild
sweating is not typical but seldom may occur and is not a serious indication. Any level of major
discomfort pain is not normal. Right away stop using the AVACEN and report the problem to
AVACEN Medical at (888) 4-AVACEN (888-428-2236).
V. Discomfort in wrist or forearm during use
Raise or lower forearm or adjust rear device feet to increase comfort.
