● Remark about battery indicate:
When there is a battery communication error:
1. Display will estimate the power according to the voltage and show the battery level
accordingly;
2. No battery percentage information shown
3. Range information show hypen - - - -

19
4. When the voltage is lower than the under voltage（considering the current influence the
voltage, change to the voltage value when the current is 0）.
Before communicate build after turn on the display, display will not show battery percentage
information. Battery bar show full level and blink at 2Hz. When the battery information read,
battery bar stop blink and show the percentage information. If communication have not built
successfully, battery bar will stop blink and not show the percentage information.
