Q: The projector has been exposed to rain during
an outdoor show without the Rain Cover installed.
What shall I do next?
A: It is necessary to remove the laser projector from its
flight case as soon as possible - within 24 hours at the
latest after the show, and let both projector and flight case
fully dry out.
NEVER turn ON the projector before it is 100% dry inside
out.
When ready, please check the status of the anti-humidity
cassette containing silica gel. For more information about
this topic, go to the User manual (chapter Maintenance).
Insufficient drying of the projector and its flight-case
can cause permanent damage to the projector (mould,
corrosion) and voids the warranty. Powering up wet
or dump projector can cause electrical shock, injury, or fire
risk. It can also cause permanent damage to the projector,
in which case the warranty is voided.
Q: Is the Rain cover accessory suitable for long term
protection against outdoor weather conditions?
A: No. The Rain cover was designed as emergency
protection against rain or snow for short term outdoor
use. During intense precipitation and winds, it can
get soaked with water. Therefore, removing the
rain cover from the projector after every use and
letting it dry together with the projector is necessary.

can cause permanent damage to the projector (mould,
corrosion) and voids the warranty. Powering up wet
or dump projector can cause electrical shock, injury, or fire

in which case the warranty is voided.
Q: Is it possible to use the Rain cover for a projector
that is set other than horizontally (i.e. when projecting
upwards)?
A: No. Our Rain cover works efficiently ONLY for projectors
set in a horizontal position - that’s with rubber feet towards
the ground.
If the Rain cover is used any other way, it won’t protect your
equipment.
Q: At low temperatures, the laser projector won’t start.
A: The operating temperature range for Kvant laser
projectors is +10°C (50°F) to +35°C (95°F).
If used outside of this range, we recommend
using the Kvant Monsoon. This robust and durable
enclosure will protect your delicate equipment,
such as laser projectors, against harsh weather
conditions, extreme temperatures and high humidity.
As a temporary solution, you can use an electric heater
to pre-heat the air entering the laser projector. Place the
heater at the correct distance from the projector, so when
the air enters the laser projector, it is within the range
+10°C (50°F) to +25°C (77°F). The projector may get damaged
if the heater is placed too close to the projector’s airflow
inlets or rear control panel.
Q: Laser projector stops working or even won’t start
at high ambient temperatures.
A: The operating temperature range for Kvant laser
projectors is +10°C (50°F) to +35°C (95°F). Using projectors
in an environment with air temperatures within 35°C (95°F)
to 45°C (113°F) is not harmful to the projector, but limits its
ability to disperse the heat efficiently, resulting in lowered
nominal power output or complete cutoff.
There is a risk of permanent damage to the laser
projector if used in temperatures exceeding 45°C (113°F),
in which case the warranty is voided.
Never place and use projectors near objects that
generate excessive heat, such as radiators, powerful
discharge lighting, or warm air outlets.
For the use in temperatures exceeding 35°C (95°F),
installing the projector into the Monsoon box with a built-
in AC unit is highly recommended.
As a temporary solution, you can use a small AC unit and
direct it ’s output towards the projector’s intake fans.
Q: Is it possible to do modifications to the electronic
circuitry of the laser projectors?
A: It is not allowed to modify the electronic circuitry
of laser projectors without prior authorization and
approval of Kvant’s technical support representative.
Any unauthorized modifications will result in immediate
warranty termination.
There is a risk of electric shock and the risk of injury
or property damage by laser radiation. Unauthorized
modifications of the circuitry may cause a change in the
projector’s functionality and specifications, making
it incompliant with regulations and standards of Class
IV laser devices.
Q: What if I feel a small electric shock when touching the
metal parts of the projector’s housing?
A: Turn off the projector immediately. Disconnect the
projector from the AC mains power supply. A qualified
electrician must check the mains power cable and the
socket.
The two common reasons are:
1. Too long AC mains power cable with joined cables
N (blue) and PE (yellow-green). The 3-wire connection
is essential.
2. Disconnected, not connected, or interrupted PE wire
in AC mains power cable or AC wall plug.
Q: What if I feel a pretty strong electric shock when
touching the metal parts of the projector’s housing?
A: There is a danger of fatal electric shock! Turn off the
projector immediately. Disconnect the projector from the
AC mains power supply. A qualified electrician must check
the mains power cable and the socket.
