A. PERFORMANCE CONTROL SETTINGS
1. It is vital to match performance control settings to your level of function and ability.
2. Consult your health care professional and your supplier to select the best control set-
t
ings for you.
3. Check and adjust the settings every six to twelve months (or more often, if needed).
4. Adjust the control settings immediately if you notice any change in your
ability to:
• Control the joystick.
• Hold your torso erect.
• Avoid running into objects.
5. Control Settings are adjusted through the use of the DTT Programmer. See your sup-
plier if you do not own a DTT Programmer.

board Programmer or RNET PC Programmer. (See RNET OBP Owners Manual for full pro-

Programming the Chair:
a. Access via OBP (On-board Programmer), DTT (Diagnostic Test Tool), or the PC
Programmer. Each of these require inline connection to the communication cable.
b. Program as needed.
c. Remove Dongle or recycle power.
NOTE– Review the RNET OBP Owner’s Manual for more details on how to program your chair.
C. THERMAL ROLL-BACK
Your chair has a thermal roll-back circuit. This protects the controller from damage due to
overheating. In extreme conditions (such as repetitive hill climbing) the circuit will decrease
the power to your motors. This allows the chair to operate at a reduced speed. When the
controller cools, the chair will return to normal speed.
