How to preserve the battery: When not in use over an extended period of time, store the headlight in a
cool and dry environment as well as with approx. 30 - 50 % residual capacity.
If the battery is discharged to below 10% capacity and then fully charged again, the battery recalibrates
itself. Occasional calibration helps to ensure that the remaining lighting capacity is always displayed as
accurately as possible.
Duration of charging
Original Busch + Müller power supply unit: approx. 3 h
Alternative USB power supply units/USB connection to computer: up to approx. 5 h
We do not assume any liability for damage caused when using alternative power supply units.
Battery charging with energy generated by cycling
With E-WERK (type 361) or USB-WERK (type 361BW) from Busch + Müller, the current of a hub dynamo
can be used to charge the IXON Rock while cycling.
8 Operation & display
High-Power: abt. 100 Lux, more than 2.5 h run time, consistently bright light
Mid-Power: abt. 50 Lux, more than 6 h run time, consistently bright light
Low-Power: abt. 15 Lux, 25 h approx. run time, consistently bright light

When the battery is low, the light mode is automatically switched off. Higher light modes and the
power bank function are therefore no longer possible for protection against exhaustive discharge.
Switch ON/OFF
ON/OFF: Press switch for 2 seconds
To switch between High Power/Mid Power/Low Power functions: Press button briefly.
Battery level indicator for lateral indicator LEDs
5 blue LEDs = 100-80 %
4 blue LEDs = 80-60 %
3 blue LEDs = 60-40 %
2 blue LEDs = 40-20 %
1 blue LED = 20-10 %
1 blue & red LED = < 10 %
The accuracy of this display depends on the charge level, temperature and operating mode. When
the headlight is switched off, the battery level can be displayed by briefly pressing the switch.
Light mode indication by LED in switch
High-Power mode: Indicator LED in switch light up blue.
Mid-Power mode: Indicator LED in switch light up blue & red.
Low-Power mode: Indicator LED in switch lights up red.
