4 Wireless InertiaCube3 Power Requirements (Battery)
The Wireless InertiaCube3 requires 5.2 to 9 VDC at a drain of 60 mA. Voltages above 9 Volts
can cause permanent damage to regulators. Voltages below 5.2 VDC will cause the accuracy of
the InertiaCube3 to degrade. The green LED will flash when the detected voltage is at 5.2 VDC,
indicating a low power situation and will continue flash until the power is raised above 5.5 VDC.
If the detected voltage drops below 4.5 VDC, the device will stop operating and go into a very
low drain mode. A non-rechargeable (alkaline) 9 VDC high performance battery can last over 8
hours. Four, non-rechargeable (alkaline), AA or AAA will work as well. Rechargeable AAA
batteries typically only produce 1.2Volts so 4 of them are not sufficient.
5 InertiaCube3 Mounting Recommendations
Magnetometers in 3 axes of the InertiaCube3 are used to establish an absolute heading reference
and to correct for heading gyro drift. To get the best accuracy, the InertiaCube3 should be
mounted as far away from large magnetic sources; either ferrite materials like steel, some types of
batteries or magnets sometimes used in Head/Helmet Mounted Displays (HMDs). For this same
reason you should use the nylon mounting screws supplied with the IC3. Even long non-
magnetic metal screws can effect the magnetic calibration.
Please review the detailed information about mounting and orienting the InertiaCube3 for
optimum performance in Section 3.6 of the InertiCube3 Manual.
