Protection from fire:
1. Take care of not placing the unit near sources of heat (e.g.
powerful amplifiers, fog machines).
2. Take always care of sufficient air convection in the unit’s
environment to avoid overheating, especially when mounting in a
closed environment. Make sure air convection slots are not
blocked. Do not operate this unit in environmental temperatures
exceeding 40 degrees Celsius.
3. Check the total maximum power of your AC wall outlet if you
connect several units to one wall outlet and avoid any overloading.
Protection from injury and damage:
1. Never use any accessories or modifications not authorized by the
manufacturer of this unit.
2. Choose a location for operation where the unit is protected from
vibration and where a fixed mounting position is provided. In case
of overhead-mounting, follow appropriate rigging rules and your
country’s regulations for rigging safety. See appendixes if any.
3. Before plugging the AC cord in the wall outlet, check whether the
AC mains voltage and frequency is the same as this product is
specified for. Whenever your AC plug should not match the wall
outlet, contact you dealer immediately.
4. If fluids have spilled into the unit or small parts have intruded the
unit, immediately switch off the unit and hand it over to the
authorized service for a security check.
5. Disconnect the unit from AC supply by pulling the AC plug out of
the wall outlet or the unit’s AC socket during a thunder-storm in
order to avoid any damage on the unit due to AC voltage peaks.
6. In cause of not correct function of this unit or damaged AC cord or
other damaged parts, pull immediately the AC plug out of the wall
outlet and hand the unit over to the authorized service for a
security check.
7. To meet all aspects of functionality and security during mainte-
nance work to be preformed on this unit, all parts should be
replaced by genuine spare parts. Consequently, take care of your
dealer or maintenance company to be authorized by the
manufacturer.

Health advice
This unit produces and absorbs electromagnetic radiation. The strength of radiation and
the sensitivity for disturbing interference matches the CE and FCC requirements. A
corresponding sign is printed on the backside of the unit. Any change or modification
may affect the behavior of the unit concerning electromagnetic radiation, with the CE
requirements eventually not to be met any more. The manufacturer takes no
responsibility in this case.

The pre-programmed soft fade or hard switching patterns can be chosen by means of
CH1 whilst CH2 is used as a dimmer channel. CH3 allows to set the fade time or
pattern speed from slow (value 50) to very fast (value 255). If channel 4 reaches a DMX
value of 50 or above a strobe will be added to the chases. The strobe speed can be
adjusted from slow (value 50) to 23 flashes per second (value 255).
Note:
Whether the unit works in static colour mode or pattern mode only depends on
the value of channel 3. So make sure the value of channel 3 is lower than 50 to be in
static colour mode. Otherwise you will be in pattern mode.
In this mode the potentiometer (1) is disabled.
Addressing has to be done as follows:
001 first device
(CH 1-4)
*factory default*
005 second device
(CH 5-8)
009 third device
(CH 9-12)
013 fourth device
(CH 13-16)
and so on.
This setting is stored even if the device is switched off.
Display on/off
If you wish the display to be lit only when a change in operation is made, the DIP switch
(10) should be in the position off. Now if any of the buttons is not pressed for more than
approximately 25 seconds the display is switched off. As soon as one of the buttons is
pressed again, the display switches on immediately. In this case the first touch of the
button is ignored in respect to the normal function of that button.
Key lock
Pressing the MODE button (5) for longer than 3 seconds locks all the buttons (5-7) and
the potentiometer (1). The display shows “LOC” in alteration to the mode (changing
every 2 seconds). Pressing the MODE button again for more than 3 seconds unlocks
the button- and potentiometer-functions. Please note: If the display is in OFF-mode it
will take approximately 25 seconds before the display switches off. It will be switched
on again if any key is touched and will switch off again after 25 seconds if the keys are
not unlocked by the procedure mentioned above.
Termination
To avoid interference the last unit of a DMX-chain should be terminated. Therefore the
DIP switch (9) of the last unit in the DMX-chain must be switched ON.
