CHARGING TOOL
The TECH450 is shipped with a charged battery. It is recommended that the tool is charged 2+
hours before first use. For optimum performance, always keep it sufficiently charged.
The TECH450 will notify the user when the battery has low power, and the battery icon will
change colour from white to red. When there is an insufficient amount of power remaining in
the battery, the TECH450 will save all of the TPM Data and then power itself off.
POWER ON/OFF SEQUENCE
Press and hold the power button for two seconds to power on the tool. To power off the
tool, press and hold the power button for three seconds.
Auto power off is after 10 minutes of inactivity. This can be changed in the Settings menu.
The unit automatically powers up when the charger or USB port is in use – auto power off is
not operational. The tool cannot be operated when plugged in.
