Safety information

This Instruction Manual uses signal words to alert you regarding potential hazards or important
information.

The meaning of the signal words is listed below:

Describes a hazardous situation which, if not avoided, could result in a fatal accident or serious injury.
Indicates information considered important, but not hazard-related (e.g. information related to property damage).
The symbol is used to provide other useful information about your new bicycle component.
Products made by Busch + Müller are suitable for use on bicycles cycling on a firm surface. Avoid any extreme use, and never ride down stairs or perform jumps, stunts, tricks, bunny hops or vertical descents on rough terrain.

Legal regulations

Before cycling on public roads you must, at any time, be aware of and observe the applicable national laws and statutes as well as local regulations. For information, either consult the Road Traffic Regulations or – depending on your respective place of residence – other sources for information.

Assembly

General information

Make sure your headlight is not covered under any circumstances. Take care that the headlight has been mounted and aligned as prescribed. For headlights with a separate reflector, make sure that the make sure that the reflector is aligned perpendicular to the road surface.

In Germany, the prescribed mounting height for headlights 1 and reflectors ranges between about 400 and 1,200 mm. For details, consult your national Road Traffic Regulations or contact a local bicycle specialist retailer. Always make sure the headlight is mounted and aligned in a way to ensure that oncoming traffic is not blinded.

To avoid falls, accidents and severe injuries, always use the enclosed Busch + Müller assembly bracket. If unsuitable or improperly positioned brackets are used, the headlight may probably come loose, slide down and, in the worst case, get caught in the wheel spokes.
Never mount brackets on forks or seat stays!
Never mount brackets on conical components!
Make sure to tighten all screws in a way to ensure the headlight cannot move all by itself. This is especially important when cycling on uneven terrain.

Headlight alignment

Align the bicycle headlight in a way to ensure that oncoming traffic is not blinded. On a completely flat road, the horizontal light edge (cut-off line) must always be visible on the road!

Do not use the bicycle if the light beam of your headlight is misaligned or the headlight is too loose.
Only align or tighten the bicycle headlight when the bicycle is not moving. Blinding oncoming traffic can lead to accidents. Before aligning the bicycle headlight loosen the bracket retaining screw. Make sure to retighten this screw again after aligning the headlight so that neither the screw nor the headlight can come loose or move all by themselves.

Never look directly into the light of the bicycle headlight when switched on .

IQ-X Assembly

Securely attach the headlight to the bicycle using the enclosed Busch + Müller bracket so
that it does not adjust itself, and its position on the bicycle cannot change. This adjustment must be checked before initial use. If other brackets are used, no guarantee can be given for secure attachment. Never mount on the fork leg or on conical components.
Mounting example fork crown: First loosen the existing screw on the fork crown of your bicycle.
Insert this screw through the screw hole provided at the lower end of the Busch + Müller bracket and then tighten it again to ensure the the headlight cannot come loose or move all by itself.

Suspended assembly

ATTENTION: If the headlight is to be mounted in a suspended position, please ensure to not simply turn it or place it upside down. Other road users would be dazzled!
In order to align the headlight correctly in a suspended position, loosen the plastic ring around the headlight and turn it by 180°. For this purpose, detach the headlight 1 rom the Busch + Müller bracket first and then slightly spread the circumferential plastic ring and move the ring around the headlight 1 by 180°.

IMPORTANT: Make sure that the cable outlets on the headlight always point straight down. This is the only way to ensure that the light pattern of the headlight 1 is ideally aligned and protected from water penetration in the best possible way.
The headlight must be mounted either upright (Busch + Müller bracket and the cable outlet pointing in exactly the same direction) or suspended and rotated by 180° (Busch + Müller bracket
and the cable outlet pointing in exactly the opposite direction). Otherwise, there is a risk that the headlight might adjust all by itself.

For suspended assembly, the reflector must not be mounted „overhead“. Please mount the the reflector elsewhere parallel to the road at a height between 400 and 1,200 mm.

Connection

Two double cables of different lengths are mounted in the headlight Connect the long cable with the hub dynamo (shorten if necessary), and the short cable (with plugs) with the rear light. For this purpose, tilt the headlight forward, if necessary, and either use the existing cable on the bike or connect it with the enclosed double cable.
If you do not use the rear light cables, the plugs should be insulated in order to prevent malfunction.
Always ensure correct polarity.
Black wire = current / white/black wire = mass.
Cables on the headlight must never be cut off completely. The headlight is only suitable for use with hub dynamos, not for side running dynamos.

Standlight

The stand light function is always ready for operation, entirely maintenance-free, and it works without batteries or accumulators.
While cycling, a small amount of the energy supplied by the dynamo is stored in a capacitor. After about minutes of cycling, the capacitor is fully charged. When stationary, this stored energy supplies power to the headlight LED, the LEDs in the lateral light slots and the blue indicator LED in the rear button of the headlight They keep on shining. The stand light can be switched off prematurely by pressing the button on the rear side of the headlight .

Operation

By pressing the button on the rear side of the headlight it is switched ON or OFF. When switched on, the headlight is always in the SENSO mode. (A prerequisite for a functioning SENSO operation is a constantly running hub dynamo). Even if the headlight was switched off while cycling, it is switched on again in the SENSO mode when cycling again after an extended stop. Exception: If the headlight is switched off while stationary in order to shut down the standlight function prematurely, it remains switched off initially even when continuing the ride. In bright light, the headlamp operates in the daytime mode. The headlight provides dimmed light on the road while the additional LEDs shine with full brightness ensuring maximum visibility for oncoming traffic! (The indicator LED in the rear button lights up blue with full intensity while the light emerging from the lateral light slots is white.)

At dusk and in darkness, the headlight automatically switches to the night mode. The headlight shines on the road. The additional LEDs do not light up. Maximum visibility on the road, additional visibility for oncoming traffic! (The indicator LED in the rear button provides a blue-dimmed light, and white-dimmed light shines through the lateral light slots). The headlight‘s light/dark sensor has a changeover delay of approx. 8 seconds from the night to the day mode. This provides additional safety. At night, the headlights of passing cars do not affect the sensor. The headlight cannot accidentally switch to day mode.

Never adjust the range of your headlight while cycling. This may cause severe falls and injuries.

Additional information

Cleaning: Protect your headlight from the effects of high pressure water. For example, never point a water hose or high-pressure cleaner directly at the headlight.
Transport: If you transport your bicycle by car in rainy weather, cover the headlight with a plastic bag, for example, to protect it from moisture.
Teletachimetri: The electronics of radio speedometers and LED headlights can interfere with each other. Interference can be reduced by keeping the distance between the LED headlight and the radio speedometer as large as possible, and the shortest possible distance between the transmitter and receiver of the radio speedometer.
Disposal: Electronic components must not be handled as household waste but are to be disposed of as hazardous waste.
Overvoltage protection: Overvoltage protection of the headlight is also active without a rear light connected.

Liability

In addition to the above-mentioned exclusions of warranty, we do not assume liability for any and all other damage caused by improper handling (e.g. dropping the system, inadequate safety of assembly and its consequences, submersion in water or other liquids etc.). Likewise, warranty is excluded if products are opened.

Have fun with your headlight and enjoy safe cycling!
