shielded cable (This cable may be purchased at almost all professional
sound and lighting stores). Your cables should be made with a male
and female XLR connector on either end of the cable. Also remember
that DMX cable must be daisy chained and cannot be split.
Notice: Be sure to followfigures two and three when making your own
cables. Do not use the ground lug on the XLR connector. Do not con
nect the cable's shield conductor to the ground lug or allow the shield
conductor to come in contact with the XLR's outer casing. Grounding
the shield could cause a short circuit and erratic behavior.

Special Note: Line Termination. When longer runs of cable are
used, you may need to use a terminator on the last unit to avoid erratic
behavior. A terminator is a 110-120 ohm 1/4 watt resistor which is con
nected between pins 2 and 3 of a male XLR connector (DATA + and
DATA -). This unit is inserted in the female XLR connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator
(ADJ part number Z-DMX/T) will decrease the possibilities of erratic
behavior.
Termination reduces signal errors and
avoids signal transmission probloms

Fuse Replacement
First unplug the power. The fuse holder is located next to the power
cord. Using a flat-head screw driver unscrew the fuse holder. Remove
the bad fuse and replace with a new one.

Cleaning
rv
Fixture Cleaning: Due to fog residue, smoke, and dust cleaning the
internal and external optical lenses and mirror should be carried out
periodically to optimize light output. Cleaning frequency depends on
the environment in which the fixture operates (I.e. smoke, fog residue,
dust, dew). In heavy club use we recommend cleaning on a monthly
basis. Periodic cleaning will ensure longevity, and crisp output.
1. Use normal glass cleaner and a soft cloth to wipe down the out
side casing.
2. Use a brush to wipe down the cooling vents and fan grill.
3. Clean the external optics and mirror with glass cleaner and a soft
cloth every 20 days.
4. Clean the internal optics with glass cleaner and a soft cloth every
30-60 days.
5. Always be sure to dry all parts completely before plugging the unit
back in.

Trouble Shooting
Trouble Shooting: Listed below are a few common problems that
you may encounter, with solutions.
No light output from the unit;
1.
Be sure the external fuse has not blown. The fuse is located on
the rear panel of the unit.
2. Be sure the fuse holder is completely and properly seated.
Unit does not respond to sound;
1. Low frequencies (bass) should cause the unit to react to sound.
Tapping on the microphone, quiet or high pitched sounds may
not activate the unit.
