If the touchscreen is held for 10 seconds on power-up, it will enter a forced firmware upgrade mode.
This state can be confirmed by listening to the startup beeps. If the normal startup tone (3 quick
ascending beeps) is followed by a 10 second delay, then a single long beep, then there is pressure on the
touchscreen which the main processor interprets as a request to force a firmware upgrade.
Screen protectors or mounting methods cannot result in pressure being applied to the LCD touchscreen.
If mounted “under deck” or in any way squeezed by the mounting method, make sure the pressure is
light, otherwise it can deflect the display bezel far enough to apply pressure against the LCD touchscreen.
To test, loosen the mounting method to relieve the pressure, then press firmly in all 4 corners of the LCD
with your finger – this will ensure the LCD pressure is removed by creating clearance between the plastic
case and the touchscreen.

SYMPTOM: Fuel gauge reading changes drastically as charge/discharge current changes
SOLUTION:
This is most likely caused by an incorrectly configured BumpTag.
The fuel gauge primarily relies on pack voltage to determine the fuel level of the pack. However, it fine-tunes that
reading by compensating for any internal voltage drop/rise in the pack due to the amount of current flowing through the
pack. This calculation uses the rated Cell Internal Resistance which gets its default value from the Pack Max C-Rating
and rated Capacity.
So if either the Pack Max or Capacity fields of the BumpTag are set incorrectly, then the Fuel Gauge readings will not
be accurate when the pack is being charged or discharged. The solution is to make sure your all of the Factory Ratings
fields are programmed correctly in the BumpTag.
