9. OPERATION INSTRUCTIONS
NOTE: Install APT-1 for arms or legs exercise as described in the previous
chAPT-1ers.
9.1. 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-1): 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 se-
lection push switches (Figure 3-4).
Step 4: Rotate the APT-1 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 (Table 1, Appendix 1).
9.2. 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 se-
lection push switches (Figure 3-4).
Step 3: Rotate the APT-1 handgrips or footrests forward or back-
wards. 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).
