1. INTRODUCTION
The APT is an electric exercise machine used for the improvement of physical abilities. The APT provides the user
with a variety of exercise options and modes of operation that meet a broad range of physical needs.
A wide range of accessories are available that offer many exercise options and make the APT suitable for the
maintenance of fitness and physical well being.
The APT can be operated in either the ACTIVE mode at varying degrees of resistance or in the PASSIVE mode at
adjustable speed and torque levels. In the PASSIVE mode it is also possible to combine PASSIVE with ACTIVE train-
ing by using physical effort in conjunction with the electrical operation of the motor. The APT functions forwards or
backwards and is suitable for arm or leg exercises (upper or lower limbs).
The APT’s light weight makes it portable, easy to store and convenient to use in the comfort of one’s home. The unit
is also suitable for use in health care institutions.
Use of the APT is recommended for the maintenance of muscle strength, flexibility, muscle tone, endurance and gen-
eral fitness for users of all ages.

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).

APT – User’s Manual Rev.C_11/19/13 16
6.3. PASSIVE mode
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 PASSIVE mode, the range of movement is reduced
and the degree of resistance that the motor can overcome is increased.
Step 2: To activate the passive mode from the stand by position (after the electrical power is supplied to the
APT): Press the button two times, until the green PASSIVE mode indicator (Figure 3-3) will light up.
From the ACTIVE mode – press once only.
Step 3: Set the desired rotation force and speed by pressing one of the five exercise level selection push switch-
es (Figure 3-4). 1 = lowest force, 20 rpm / 5 = highest force, 60 rpm
Step 4: Hold onto the handgrips (for arm exercise) or secure both feet to the footrests (for legs exercise). Make
sure that APT is placed at a comfortable distance for exercise by turning the crank arms one complete
revolution.
Press the button for forward rotation.
Press the button for backward rotation.
NOTE: There will be a short delay before the APT begins to turn in the chosen direction.
Step 5: The operation force of the crank arms should rotate the arms or legs of with no effort on the part of the
user. This rotation force varies according to exercise level and crank arm mounting hole location selected
(Table 3, Appendix 1).
Step 6: To stop the rotation of the crank-arms and exit the PASSIVE mode, press the button. The indicators
will turn off and the APT will return to the stand-by position.

APT – User’s Manual Rev.C_11/19/13 17
6.4. COMBINED active/passive mode
Step 1: Operate the APT in the passive mode and work against the force of the motor by applying resistance to
the rotation of the crank arms.
Step 2: The resistance force to the rotation is displayed on the on the Bar Indicator as a percentage (%) at each
level.
Step 3: If the resistance force stops the crank arm rotation completely, the Bar Indicator (Figure 3-5) reaches
100% and the red indicator will light up. After holding this position for approximately 2 seconds, the crank
arm rotation will stop automatically.
NOTE: To restart, Press the button for forward rotation, or the button for backward rotation.
6.5. Passive mode - AUTO-REVERSE function
Step 1: Push the button to activate the AUTO-REVERSE function in the PASSIVE mode. The green indica-
tor will light up.
Step 2: Operate the APT as in usual passive or combined active/passive mode.
Step 3: When the resistance force stops the crank arm rotation completely, the Bar Indicator (Figure 3-5) reach-
es 100% and the red indicator will light up. After holding this position for approximately 2 seconds, the
crank arm rotation will stop automatically. After a short delay the DIRECTION OF ROTATION WILL BE
REVERSED. This feature also serves as an ANTI-SPASM function, stopping the motor in case of muscle
spasm and reversing the direction of rotation after a short delay.
Step 4: As long as the button indicator is lit, this function will continue to operate in the PASSIVE mode.

APT – User’s Manual Rev.C_11/19/13 18
6.6. Shut down
Step 1: To turn off the APT, from the PASSIVE mode- press the button once. From the Active mode –
press twice. The indicators will turn off and the APT will return to its stand-by position.
Step 2: Disconnect the power from the APT by first disconnecting the mains electrical plug from the electrical
socket outlet. Disconnect Power supply output connector from the APT power input socket.
CAUTION: For safe disconnection always take the mains plug out of the electrical socket before disconnecting
the Power supply from the APT.
6.7. Emergency Switch
In the event of the need to stop the APT quickly, press the red mushroom headed button (Figure 14-1) situated
on the top of the trainer body (above the control panel). This will immediately cut the electrical supply to the APT.
The button will stay de-
pressed and as long as it is
in this position the APT will
not function.
In order to restore the elec-
trical supply to the APT, turn
the knurled black disc un-
derneath the red button (Fig-
ure 14-2) in the direction of
the white arrow (Figure 14-3)
on the red button (clock-
wise). The red button will
then return to its original po-
sition.
The APT may then be re-
started as previously de-
scribed.
