Auto Power Down
To increase battery life, the unit will
automatically shut off the display and
go to a standby mode if no activity is
sensed for approximately 30 seconds.
The display will turn on when any
compression or ventilation activity is
sensed. You can also reactivate the
display by pressing the mode or start
button.
TEST MODES:
To begin a test, press the start button.
Pressing the start button will clear
all registers.
Compression Rate
In the compression rate mode, the unit
will display the average rate in com-
pressions per minute of the last five
compressions. The unit will continue to
update this average until you change
modes or push the stop button. Upon
pushing the stop button, the unit will
calculate and display the average com-
pression rate of all compressions from
the start of the present cycle.
Example: For the first compression
cycle of 15 compressions, an aver-
age rate of 60 compressions per
minute (CPM) was obtained. Then
two ventilations were applied to the
manikin. Then a second compres-
sion cycle of 15 was applied, at an
average rate of 100 CPM, and then
the stop button was pushed. The
unit would calculate and display the
overall average of 80 CPM.
Ventilation Duration
In the ventilation duration mode, the
unit will display the duration in sec-
onds of the last ventilation. The unit
will continue this display mode until
the mode is changed or the stop but-
ton is pushed. Upon pushing the stop
button, the unit will calculate and
display the average duration of all
ventilations from the start of the pres-
ent cycle.
Ventilation Volume
In the ventilation volume mode, the
unit will display the volume in liters
of the last ventilation. The unit will
continue this display mode until the
mode is changed or the stop button
is pushed. Upon pushing the stop
button, the unit will calculate and
display the average volume of all ven-
tilations from the start of the present
cycle.
TROUBLESHOOTING:
Low battery light remains on.
1. Turn power off.
2. Replace batteries.
3. Turn power on.

Child
Good = Over 0.50 liters (800 cc’s)
High = Over 2.00 liters (2000 cc’s)
Low = Under 0.50 liters (80 cc’s)
Compression Depth
In the compression depth mode, the
unit will display the average depth in
inches of the last compression. The unit
will continue this display mode until the
mode is changed or the stop button is
pushed. Upon pushing the stop button,
the unit will calculate and display the
average depth of all compressions from
the start of the present cycle.
