Time Adjustment and Timer Operation:
The run time may be set from 30 seconds to 99 minutes
and 30 seconds. Press the up and down arrow buttons next to the time display to adjust the run time.
Adjustments may be made prior to a run or after a run begins. A quick tap will adjust the time by 30
seconds. Hold down the button for 1 minute adjustments - continue to hold for 5 minute adjustments.
Press the down button once while 00:30 is displayed to access the “hold” feature. When a “hold” run
is initiated, the timer will count up to keep track of total run time. The unit will run for a maximum of 99
minutes and 30 seconds and will then shut off automatically. The “hold” run may also be terminated
by pressing the STOP/OPEN button. The total run time during a “hold” run is displayed on the time
display until the operator unlocks the lid by pressing the OPEN button or opens the lid (during the
automatic unlock after the run ends).
Speed Adjustment / RCF Display:
Press the up and down arrow buttons next to the speed
display to change to run speed. Adjustments may be made prior to a run or after a run begins. A quick
tap will adjust the speed by 50 RPMs. Hold down the button for 100 RPM adjustments. Continue to
hold for 500 RPM adjustments.
Press the RCF button at any time to convert the current speed setting to the corresponding force
value (xg). The speed may be set by RCF by holding down the RCF button while using the up/down
speed set buttons. The jumps made in the RCF value while holding down the RCF button and pressing
the up and down arrow buttons correspond to 50 RPM adjustments in speed. Since the RCF is a
function of the square of the speed, this jump size will vary.

a run. Press the STOP/OPEN button at any time during a run to terminate it.
