Indicator LED – works when rear light is switched on
The indicator LED 2 is positioned inside the rear light on the left side (when viewed in driving direction), beneath the main LED. It can best be seen when looked at from the left, not frontally.
Shines green permanently
Sufficient battery power
Green LED extinguishes
Battery must be charged (according to German road traffic regulations)
Some time after the indicator LED extinguishes, the rear light deactivates automatically to protect the battery against depth charging.
Mounting
Apply the rubber casing to the seat post with the ON/OFF symbol pointing upwards. Even though the rear light sits on the sear post at an angle, the main operating direction is aligned parallel to the road. Insert rubber mounting strap into the left clasp for a loss-proof fit of the strap. Firmly pull the mounting strap around the seat post and hook it into the right clasp. Adjust the rear light so it points exactly backwards. Suitable for seat post diameters 20-35 mm.
When the red rear light is removed from the black rubber casing, it has to be reinserted with its ON/OFF switch located beneath the ON/OFF symbol on the rubber casing.
Charging the battery
The IXXI has a firmly installed rechargeable lithium battery.
To charge it, fold open the bottom cap on the rear light. Connect the enclosed USB cable to the rear light’s micro-USB socket 3 . Connect the USB cable to the IXXI’s mains adaptor (if included), to another standard USB mains adaptor (max. 100 mA, 5 V) or to a computer. During charging, the indicator LED inside the rear light shines green. When the LED extinguishes, charging is complete. Overcharging is not possible, as the power supply is cut off automatically. When charging with other mains adaptors, no guarantee can be granted.
Charging time
With original Busch & Müller mains adaptor (ref. 447/4N) or other standard USB mains adaptors: approx. 2.5 hours When using a computer’s USB port, charging may take up to 3 to 4 hours.
Charging the battery using dynamo power
Using the E-WERK (ref. 361, setting 4.9 V/1A) or the USBWERK (ref. 361BW), a hub dynamo’s power can be used to charge the IXXI while cycling. Please note that during charging, the rear light is neither splash- nor rainwaterproof. Only charge at temperatures of at least 0°C.
