Safety notes
This device is intended for use as a multifunctional lighting instrument with movable mirror.
Use the device only as described in this user manual. Any other use or use under other oper‐
ating conditions is considered to be improper and may result in personal injury or property
damage. No liability will be assumed for damages resulting from improper use.
This device may be used only by persons with sufficient physical, sensorial, and intellectual
abilities and having corresponding knowledge and experience. Other persons may use this
device only if they are supervised or instructed by a person who is responsible for their safety.
DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!
Ensure that children do not detach any small parts (e.g. knobs or the like) from
the unit. They could swallow the pieces and choke!
Never let children unattended use electrical devices.

DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never
remove any covers.
There are no user-serviceable parts inside.
DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a pro‐
tective contact plug. Do not modify the mains cable or the plug. Failure to do so
could result in electric shock/death or fire. If in doubt, seek advice from a regis‐
tered electrician.

WARNING!
Eye damage caused by high light intensity
The lamp used in this device produces an intense beam of visible and invisible
light radiation.
Do not start the operation of the device without completely fixed covers. Never
look directly into the light source.
WARNING!
Risk of epileptic shock
Strobe lighting can trigger seizures in photosensitive epilepsy. Sensitive persons
should avoid looking at strobe lights.
Safety notes
LED scanner
10

WARNING!
Risk of burns
The surface of the device can become very hot during operation.
Do not touch the device with bare hands during operation, and after switching
off wait for at least 15 minutes.
Safety notes
JunoScan MK-II
11

CAUTION!
Risk of injury due to mirror movements
The mirror mounted at the device head may perform very fast movements (pan,
tilt) and reflect very bright light. This is also the case immediately after switching
on the device, with automatic or remote operation, and while a connected DMX
controller is in off state. Persons who are in the immediate vicinity of the device
may be injured or frightened by this.
Make sure that there are no obstacles within the movement range of the mirror,
and that no persons are in the immediate vicinity of the device before switching it
on and during its operation. If any work is to be carried out within the movement
range or in the immediate vicinity of the mirror, the device must remain switched
off.
NOTICE!
Risk of fire
Do not cover the device nor any ventilation slots. Do not place the device near
any direct heat source. Keep the device away from naked flames.
Safety notes

NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and
strong vibrations.
NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.
Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.

Installation
Unpack and check carefully there is no transportation damage before using the unit. Keep the
equipment packaging. To fully protect the device against vibration, dust and moisture during
transportation or storage use the original packaging or your own packaging material suitable
for transport or storage, respectively.
You can install the device on the wall, the ceiling or the floor.
Installation
JunoScan MK-II
15

WARNING!
Risk of injury caused by falling objects
Make sure that the installation complies with the standards and regulations in
your country. Always secure the unit by a second fastening, such as a retaining
cable or safety chain.
The load capacity of trusses or other fixtures must be sufficient for the intended
number of devices. Note that the movement of the head will cause additional
loads to the load-bearing parts.
NOTICE!
Risk of overheating
The distance between the light output and the illuminated surface must be more
than 0.5 m (19.7 in).
Always ensure sufficient ventilation.
The ambient temperature must always be below 40 °C (104 °F).
Installation

NOTICE!
Possible data transmission errors
For error-free operation make use of dedicated DMX cables and do not use ordi‐
nary microphone cables.
Never connect the DMX output to audio devices such as mixers or amplifiers.
The unit offers a 3-pin XLR socket for DMX output and a 3-pin XLR plug for DMX input. Please
refer to the drawing and table below for pin assignment.

Setup
Establish all connections as long as the unit is switched off. Use the shortest possible highquality cables for all connections.
Setup
LED scanner
18

Connect the DMX input of the device to the DMX output of a DMX controller or another DMX
device. Connect the output of the first DMX device to the input of the second one, and so on
to form a daisy chain. Always ensure that the output of the last DMX device in the daisy chain
is terminated with a resistor (110 Ω, ¼ W).
Connections in DMX mode
Setup
JunoScan MK-II
19

While the device and the DMX controller are in operation, a flashing white rectangle (DMX
indicator) in the display shows that a DMX signal is present at the input.
When you configure a group of devices in master/slave mode, the first unit will control the
other units for an automatic, sound-activated, synchronized show. This function is ideal when
you want to start a show immediately. Connect the DMX output of the master device to the
DMX input of the first slave device. Then connect the DMX output of the first slave device to
the DMX input of the second slave device and so on.

Operation
7.1
Starting up the device
CAUTION!
Risk of injury due to mirror movements
The mirror mounted at the device head may perform very fast movements (pan,
tilt) and reflect very bright light. This is also the case immediately after switching
on the device, with automatic or remote operation, and while a connected DMX
controller is in off state. Persons who are in the immediate vicinity of the device
may be injured or frightened by this.
Make sure that there are no obstacles within the movement range of the mirror,
and that no persons are in the immediate vicinity of the device before switching it
on and during its operation. If any work is to be carried out within the movement
range or in the immediate vicinity of the mirror, the device must remain switched
off.
Operation

To start up the device, connect it to the mains. After a few seconds, the fans start to work, the
mirror at the device head moves to the pan and tilt home positions and the display indicates a
system reset. After a few more seconds, the device starts to operate in the most recently set
mode.

Troubleshooting
NOTICE!
Possible data transmission errors
For error-free operation make use of dedicated DMX cables and do not use ordi‐
nary microphone cables.
Never connect the DMX output to audio devices such as mixers or amplifiers.
In the following we list a few common problems that may occur during operation. We give you
some suggestions for easy troubleshooting:
Troubleshooting
LED scanner
50

Symptom Remedy
Device not working, no light, fan
not working
Check mains connection and fuse.
Not responding to DMX controller 1. The DMX indicator in the display should flash during
data transmission. If not, check DMX connectors and
cables for proper matching and fit.
2. If the DMX indicator in the display is lit and there is no
response, check address settings and DMX polarity.
3. Try using another DMX controller.
4. Check whether the DMX cables run near or parallel to
high-voltage cables that may cause damage or interfer‐
ence to the DMX interface circuit.
If the procedures recommended above do not succeed, please contact our Service Center. You
can find the contact information at www.thomann.de.

Cleaning
Clean the optical lenses and mirrors which are accessible from the outside periodically to opti‐
mise light output. The cleaning frequency depends on the operating environment: damp,
smoky or particularly dirty environments can cause greater accumulation of dirt on the unit’s
optics.
n Clean with soft cloth using normal glass cleaning fluid.
n Always wipe dry the parts carefully.
