Use
Each MxEncoder requires a Battery Pack to operate. Be sure the power cable is routed
as shown in Figure 19 to prevent any damage to the wires.
MxEncoders need to have routine battery changes in order to ensure proper function.
It is recommended that the MxEncoder battery be replaced once a week during typical
use. Follow the Best Practices Guide (Page 54) for help on performing battery
changes. Changing a battery pack does not erase stored events on the MxEncoder’s
on-board memory.
During use, an MxEncoder Battery Pack may fall below a full charge in which case a
Low Battery Warning will be displayed in the HIT Analyzer software (Page 16). Under
typical conditions, an MxEncoder will function for 1-2 hours after this initial warning.
NOTE: To ensure continuous head impact exposure monitoring, recharging or
replacing the battery is recommended after a warning is received.
All MxEncoders have an automatic On/Off switch that helps conserve battery
life. The switch is a “proximity sensor” that senses the presence of a head in
the helmet. When not in use on the field, the MxEncoder can be activated by
placing a hand directly over the proximity sensor as indicated in Figure 20.
MxEncoders can be used on the field without the presence of the Field Case.
However, there is only on-board memory storage for 100 events. Once the
on-board memory for the MxEncoder is full, no more events can be stored,
and all subsequent events will not be recorded. The typical number of
recorded events per player, per session is 20-40, however during certain
types of play this can be much higher, so it is recommended the Field Case
always be in use during data collection.
Service
MxEncoders may be removed for routine cleaning as needed. A mild soapy solution can be used to remove dirt
from the MxEncoder surfaces. MxEncoders are not water resistant and should never be submerged in liquid.
This will cause permanent damage to the internal electronics and will render the MxEncoder non-functional.
MxEncoders have no serviceable parts. If an MxEncoder is suspected of not working, please follow the
Troubleshooting Guide (Page 47) for assistance with a non-functional MxEncoder.
