Initial Power On 

Upon initial power-on, the unit will display the company logo, battery status and software 
version.  If the battery is not installed, has failed self-test, or is in a low-temperature state, the 
battery life will show 0%.

Thermal Stabilization 

On initial power-on, the various internal sensors must thermally stabilize.  While this is 
occurring, the corresponding indicator area will be covered by a red X.  At room temperature, 
this process takes approximately 1 minute.  At colder temperatures, this may take longer.   

If the ambient temperature is below 10°C, the battery will enter a heating cycle and the battery 
status icon will be red-X’ed with a BAT HEATING indication as follows:
