6. OPERATION
INSTRUCTIONS
NOTE
: Install
APT
for arms or legs exercise as described in the previous chapters.
6.1. Active mode - ISOKINETIC operation
Step 1:
Insert the handgrips or footrests in one of the four mounting holes according to the radius and range of
motion required.
NOTE:
As the effective crank arm length is reduced in the ACTIVE mode, the amount of effort required increases
while the range of motion decreases, and vice versa.
Step 2:
To activate the active mode from the stand by position (after the electrical power is supplied to the
APT
):
press the
button. The green ACTIVE mode indicator (Figure 3-2) will light up.
Step 3:
Set the desired load level by pressing one of the five load selection push switches (Figure 3-4).
Step 4:
Rotate the
APT
handgrips or footrests forward or backward. Actual exercising force is displayed as a
percentage (%) on the Bar Indicator (Figure 3-5).
NOTE:
In this mode, an increase in the rotation speed (RPM) will lead to an increase in the exercising force (
Ta-
ble 1, Appendix 1
).
6.2. Active mode - CONSTANT FORCE Operation
Step 1:
Press the
button to activate the CONSTANT FORCE FUNCTION in the ACTIVE mode. The green
indicator will light up.
Step 2:
Set the desired load level by pressing one of the five load selection push switches (Figure 3-4).
Step 3:
Rotate the
APT
handgrips or footrests forward or backwards. The exercising force as displayed on the
Bar Indicator (Figure 3-5) will now remain constant at 50% for the selected load level, irrespective of the
crank arm rotation speed (
Table 2, Appendix 1
).
