How to install MyChron 3
Now you can start installing MyChron 3 on your kart.
It is recommended to follow these instructions in order to preserve your
instrument and to capture consistent and accurate data.
Installing and changing the display batteries
Two AAA alkaline batteries power MyChron 3. The batteries provide
approximately 40 hours of use. When the batteries require replacement ( < 2
Volt ), a battery indicator will appear in the top right hand corner of the display.
If battery voltage is very low ( < 1.7 Volt ) it will also appear the text:
LOW BATTERY
If battery voltage is really too low, the system will automatically shut down.
Replace both batteries when the battery indicator appears to avoid the system’s
shutting down during a test.
To change batteries, remove the two screws on the back of the display unit. To
remove the battery pack, hold each corner of the circuit board and pull the board
away from the display unit. When inserting the battery pack, ensure that the
batteries face the centre bolt and the circuit board faces the side of the unit. The
white connector should be positioned in the top right hand corner of the display
unit, if looking at the display unit from behind.
Do not over-tighten the screws when mounting the battery cover to the
back of the display unit.
