The firmware update optimizes the charging process when you charge the battery directly inside the ST2.

• Flashing of the ST2 lights in the locked mode is reduced. Only the daytime running lights now flash.
• Display of system messages is optimized.
• Other adjustments
• The firmware update supports new functions of the myStromer smartphone app (from app version: Argentum / August 2014 ):

1. The remote locking and unlocking function is replaced by the “AUTOLOCK” function. With “AUTOLOCK”, you can activate a timer for the automatic lock on the ST2. Via app, you can determine a period of time after which your ST2 is automatically locked. To unlock your bike again, you must enter the PIN when you switch it on.
2. You will now feel the adjustments that you can make when fine-tuning the assistance mode 2 via app much more strongly than before. Speed, torque and agility.
3. New features are that you can make ST2 system settings such as time, language and units via app.

• Optimization of communication when ST2 is switched on:

1. Position is updated every 10 minutes
2. Status is updated every 10 minutes

• Optimized energy management when locked

1. Reduced energy demand when locked
2. More accurate indication of the battery charge level after unlocking
3. Bike flashes only for the first 5 minutes after locking

• New error handling

1. Smartphone recharged at the USB charging socket without generating an OMNI error
2. General stability improvements

• Battery charge display:

1. A more accurate calculation approach for the battery charge display ensures the battery is fully charged up at the end of the charging process.
2. IMPORTANT: For optimum charging results, the battery should ideally be charged and stored at room temperature. The battery cannot reach its full capacity in a cold environment.

• New indicators to display mobile network reception:

1. New indicator for GSM signal strength in the riding display
   The more bars are solid, the better the signal strength is
2. New indicator for GSM signal strength in the riding display
   Circle with a line through it = GSM and GPRS offline
   G = GPRS online
   No G = GPRS offline
   NOTE: The ST2 can only communicate via the mobile network if there is a GPRS connection. So even if the bars indicate maximum signal strength, communication will not be possible if no "G" is displayed.
3. New indicator for exchanging data packages
   - A flashing arrow pointing down means the ST2 is receiving data.
   - A flashing arrow pointing up means the ST2 is sending data.
4. New indicator if new firmware is available for your ST2
   Flashing arrow in box = update being loaded
   Arrow in box = update ready for installation. The next time you switch on/off, you will be asked whether you would like to install the firmware.

• The PIN input display disappears if there is no activity for 1 minute in the locked mode.
• Responsiveness of the touchscreen has been optimized so that commands can be input more precisely and incorrect inputs are minimized.
