About this User Guide

This User Guide describes how to set up and operate the following projectors:

 NERO 4S GS

Except where otherwise indicated, the information in this guide applies to all the
projectors listed above, that will be referred to as “NERO 4S GS”.
Information contained in this User Guide may be updated from time to time due to
product improvements and customer feedback. Visit www.sim2.com to find the latest

Safety

rear panel before removing the glass cover or side panels of the
projector. For technical service refer to trained personnel authorized by
the manufacturer.

Read this manual

Read all chapters of this manual carefully before switching on the projector. This
manual provides basic instructions for operating the NERO 4S GS projector.
Installation, preliminary adjustments and procedures that necessitate the removal of
the glass cover and the contact with electrical components, must be performed by
authorized trained technicians. To ensure safe operation and long term reliability use
only the power cord supplied by the manufacturer. Observe all warnings and
precautions. Keep the manual for future consultation.

Do not touch internal parts of the projector

Inside the housing there are electrical parts carrying dangerously high voltages and
parts operating at high temperature. Never open the housing. Entrust all servicing and
repair work to a SIM2 Authorized Service Center. Opening the housing voids the
warranty.

Disconnect the projector from the power supply

The device that disconnects the projector from the electrical outlet, is the power plug.
Ensure that the power cord plugs and the electrical outlets are easily accessible during
installation operations. Pull the plug, not the cord, to disconnect the projector from

NERO 4S Gold Series

User Guide

the electrical outlet. Use only the specified power supply. Connect the projector to the
electrical supply with rated voltage of between 100-240 V AC, 50/60 Hz and equipped
with a protective earth connection. If you are not sure of your domestic electrical
outlet, contact an electrician. Take care to avoid overloading the power socket and any
extension leads.

Switching the projector off

Pay attention to the switch off procedure for the projector. The projector must always
be brought back to the standby state to allow the projector to carry out the cooling
procedure. Should this not happen, for example due to a power cut, the projector may
enter a state of protection that leads to switch-on being blocked. This block will last
until the internal components of the projector have completely cooled down. Allow 90
seconds for the projector to cool down.

Be careful with cables

Make sure cables are routed so that people are not impeded or become a trip hazard.
Keep all cables away from children. Install the projector as close to the wall socket as
possible. Avoid stepping on power cords, make certain they do not become tangled,
and never jerk or tug them; do not expose them to sources of heat, and make sure
they do not become knotted or crimped. If the power cords become damaged, stop
using the projector and request the assistance of an authorized technician.

Disconnect the projector from the electrical outlet during storms and when not in
use

To prevent damage from lightning strikes in the vicinity, disconnect the projector
during storms or when the projector is going to be left unused for a long time.

Avoid contact with liquids and exposure to damp

Do not use the projector near water (sinks, tubs and so on); do not place objects
containing liquids on or near the projector and do not expose it to rain, humidity,
drops of water or sprays; do not use water or liquid detergent to clean it.

Place the projector on a stable surface

Place the projector on a stable surface or use a suitable ceiling mounting bracket.
Never place the projector on its side or rear, on the lens or top panel or rear.

Do not allow the projector to overheat

To prevent overheating, allow a free space of at least 0.20 m (5 in) on the rear, on the
top, and on the right and left sides of the projector. Do not obstruct the ventilation
slots. Do not place the projector near heat sources such as heaters, radiators or other
devices (including amplifiers) that generate heat. Do not place the projector in an area
where there is insufficient space (shelving units, bookshelves and so on) and in
general avoid placing it in poorly ventilated areas as this may prevent sufficient
cooling and significantly reduce lamp life.

Take special care regarding movement of the lens

Do not place objects in the slots on the side of the lens and also ensure that vertical
lens movements are not impeded by external objects.
Do not hold the projector by its lens.

Do not pickup the projector by its lens.

Do not insert objects through the openings in the projector

Make sure that no objects are inserted inside the projector. If this should occur,
disconnect the projector from the power supply immediately and call an authorized
technician.

Power saving

We advise disconnecting the projector from the power supply when not in use. In this
way you will achieve considerable power savings while at the same time protecting
internal electrical parts from wear.

Do not use under the following conditions:

 In extremely hot, cold or humid environments

◦ Ensure that the ambient room temperature is within 5°C ~ 35°C
◦ Relative humidity is 10% ~ 85%

 In areas susceptible to excessive dust and dirt.
 Near any equipment generating a strong magnetic field.
 In direct sunlight.

Notice

The projector has been subjected to exhaustive operating tests by SIM2 to guarantee
the highest quality. The projector light source life should thus initially be around 30-60
hours. In addition to the customary checks, the Quality Control department also runs
additional statistical tests before shipment. In such cases, the packaging may show
signs of having been opened, and the hours of light source operation may prove to be
higher than those normally shown when only standard tests are performed.

As the optical system of the NERO 4S GS is extremely compact and has the purpose of
developing very high brightness and contrast, it is possible that a small quantity of
light is visible outside of the projection area and will vary depending the zoom and
shift setup. This characteristic of the optical system is to be deemed as normal. In
order to reduce this effect SIM2 recommends that the area surrounding the
projection screen is as dark as possible.

4 Installation

This section provides instructions for the installation of the NEOR4 projector.

Important: Installation procedures should be performed by a qualified AV system

specialist.

Location

When installing the NERO 4S GS projector, take the following considerations into
account.

Installation Type

Select the installation type that best suits your needs:

 front or rear projection
 floor or ceiling mount

Cooling

Make sure that the planned location for the projector has adequate ventilation. Check
that room temperature is below 35° C and that the projector is away from heating
vents. Ensure a minimum 0.20 m (5 inch) clearance on the left, right and rear sides of
the projector.

Power Outlets

Verify that the powers outlets are grounded and preferably shielded from power
surges and fluctuations. A UPS is optional. NERO 4S GS power supply operates on any
nominal line voltage between 100-240 V AC, 50-60 Hz.

Cables

Check planned cable lengths for video and control cables and make sure these lengths
do not exceed specifications.

Ambient Light

Avoid or minimize light sources directed at the screen to preserve the quality of the
projected image.

NERO 4S Gold Series

User Guide

19

Mounting

The projector can be Floor mounted (upright) or Ceiling mounted (inverted). Choose
the method that best suits your installation.
The NERO 4S GS projector has been design to be submit the EN60950/UL950 Safety
Norms with it's glass cabinet.
Nevertheless, even if the best materials and adhesives available in the market, in
order to guarantee a safe application on the long long run, exclusively for the ceiling
mounting applications, SIM2 has equipped the projector with glass safety screw that
are aesthetic part of its cabinet (see K at page 15).
To determine where to position the projector, consider the size and shape of your
screen, the location of your power outlets, and the distance between the projector
and the rest of your equipment.

Important: The projection lens is centered to the chassis . Make sure the centerline of

the lens is centered horizontally to the center of the screen.

Floor Mounting

Place the projector on a secure and flat surface (such as a table or a shelf). Adjust the
two elevator feet at the bottom of the projector until the projector is level on all sides.
Rotate the adjustable feet counter clockwise to raise the projector or clockwise to
lower it. Repeat with the remaining feet as needed.

NERO 4S Gold Series

User Guide

20

Ceiling Mounting

Invert the projector and suspend it from the ceiling using a specific brkt4 bracket,
described in the chapter 10, at page 55.

Orientation

By default, the NERO 4S GS is configured for a Front installation (projector installed
upright and in front of the screen). If the projector is installed behind the screen or
inverted, you can use the image orientation function of the projector.

Vertical Lens Shift

Ideally, the projector should be positioned at a right angle to the screen and in such a
way that:

 the lens center and screen center are aligned with each other
 the projected image fills the screen perfectly

Keystone

If the projector is ceiling-mounted and the screen is lower than the projector, you may
need to tilt the projector by adjusting the ceiling mount. If you do so:

 the top and bottom borders of the image will be unequal in length
 the sides of the image will be inclined

Use the Allen Screw (of 2.5mm or 0.0984 inch) available in the standard accessories in
the package. When the horizontal and vertical shifts are centered to the lens, the leds
signal this status with a flashing.

If you want to use the Perfect-Fit function, your setup should not have any horizontal
optical shift.

NERO 4S Gold Series

User Guide

22

Connections

Proceed as follows to connect the NERO 4S GS to video sources, control devices,
screen control systems and AC power.
When connecting your equipment:

 turn off all equipment before making any connections
 use the correct signal cables for each source
 make sure cables are routed so that people are not impeded or become a trip

hazard

 ensure that the cables are securely connected (tighten the thumbscrews on

connectors that have them)

HDMI The major benefits of this signal type are:
 best image quality, because the signal is carried in the digital domain throughout

the entire signal path

 highest available resolution, because video sources can deliver full resolution

content via HDMI only

 optimization of several image parameters (color space, aspect, signal range, over

scan), thanks to auxiliary information (AVI infoframe) sent by the source device

together with the signal.
If your source has dual HDMI outputs, we would recommend direct connection to the
projector from one of the HDMI connections and the second HDMI output to the
input of an appropriate AV receiver/processor for audio.
Sources with a DVI-D output can be connected to the HDMI input of the projector
using a suitable DVI-D to HDMI cable. In this case no auxiliary information is sent from
the source to the projector.

Note: HDMI uses a code known as HDCP (High-bandwidth Digital Copy Protection),

which protects the recorded supports from being copied illegally. The connection
between the source and display requires that the two devices perform a handshake
and exchange code keys before being able to display an image. The InstaPort
technology allows a simultaneous pre-authentication of every attached device at the
same it is connected, reducing drastically the time required for HDMI source
switching. For this reason you may note a slight delay before the image appears on the
screen, but it is perfectly normal.

 DispalyPort is a digital display interface developed by the Video Electronics

Standards Association (VESA). The interface is primarily used to connect a video

source to a display device. DisplayPort can be used to transmit audio and video

simultaneously, but each one is optional and can be transmitted without the

other.
 Graphics RGB Input for Personal Computer and other sources that outputs RGB or

YPrPb signals. These sources must be able to provide separate H/V sync or

composite H+V sync.

NERO 4S Gold Series

Live Colors Calibration software (LCC)

To aid calibration, the NERO 4S GS projector, feature the new SIM2’s advanced Live
Colors Calibration 5.0 software that enables professional calibration of many
projection parameters such as complete adjustment of the primary, secondary and
white point color coordinates. This PC-based software gives calibration experts
unprecedented control over the projector image quality.
SIM2 recommends the use of LCC software to calibration experts only, by using
spectrophotometers or color probes to correctly analyze and adjust the colorimetry.

Any NERO 4S GS is factory adjusted to reach the DCI standard in SIM2 premises:
selecting Display Mode “Natural” (or “HDR10” or “HDR-HLG”), and Color Gamut “LCC­DCI”, (Color Temperature is “D65”). These setup reproduce, as close as possible, the
image the way the movie director intended; colors, color temperature, brightness and
gamma settings are all configured to standard reference levels. However, some fine
tuning would be necessary to adapt NERO 4S GS to your screen, environment and
source. The NERO 4S GS is compatible with Klein K10-A Colorimeter.

Display Mode

There are many factory presets optimized for various types of images:
NATURAL: this mode is intended to reproduce, as close as possible, the image the way
the movie director intended.
DYNAMIC: this mode is suitable for showing PowerPoint presentations when the
projector is connected to the PC.

BRIGHT: maximum brightness from PC input.
CINEMA: default settings for home theater.
SPORT: select this mode to increase the brightness and response time level for

enjoying sporting events and video games.
HDR10: this mode is intended to reproduce the images in High Dynamic Range. This
mode is the default mode for the HDR images and it will recalled every time the
projector will detect an HDR content inside the signal.

UserHDR10: user's settings for the HDR signals.
HDR-HLG: this mode is intended to reproduce the images processed with the Hybrid

Log Gamma curve.

UserHDR-HLG: user's settings for the HLG signals.
USER: user's settings.

Note: When the projector recognize an HDR content, in the signal, it will switched the

Display Mode in HDR or UserHDR10. Between these two last modes, it will selected the
last one selected from the user. Example: if the projector is displaying a video, not
HDR, and the present Display Mode is Natural, when the user will switch to an HDR
signal, also the projector will change the present Display Mode in HDR10 or
UserHDR10. At the moment that the user will come back to the signal without HDR
content, also the projector will select the previous Display Mode, for this example, the
Natural.
Same behavior when the projector recognize a video processed with the Hybrid Log­Gamma: it will switched the Display Mode in “HDR-HLG” or “UserHDR-HLG”.

Note: The HDR10 signals are processed only if they coming from the HDMI2 input, that

is compliant with the standard HDMI v.2.0a - HDCP 2.2.

Note: The HDR-HLG signals are processed only if they coming from the HDMI2 input.

Note: The Display Mode depends on the input source and timings. For example, the

display mode will be different from HDMI and VGA. If you change any of the image
settings, the display mode presets will be changed and saved automatically. If you
want to return to the factory default display mode, select RESET from the menu

dimensions of 100 inches, selects the preset HDR3.

Note: HDR behavior has been deeply revised. Since the launch of the NERO 4 HT

market, one of the very first 4K UHD HDR products in its category, a vast range of
contents and signal sources have become usable. This vastness of content and players
has led to a profound revision of the HDR video behavior of NERO 4, now optimized in
all situations in which it is used to project a 4K UHD HDR image.

6 Perfect-Fit

The Perfect-Fit function improves the optical light engine including a fully­programmable zoom, focus and lens shift feature, which enables a lens-free option to
create 2,40:1 images.
There is the possibility to save the settings for the positions of zoom and focus
corresponding to a video format for 10 different configurations.
To set the custom settings zoom and focus is necessary to enter the SETUP menu and
than in the Lens Functions menu.
To set the custom settings lens shift is necessary to enter the DISPLAY menu.

In the case of off-axis projection, zooming in and out, you get a changing of the center
of the image corresponding to the amount of the off-axis. This changing amount must
be compensated with the vertical and/or horizontal shift (regulated manually).

A correct setup for 2,35:1 image format, with a 16:9 format inside, is to do not have
an horizontal optical shift. The digital vertical lens shift has at maximum the 15% of
regulation, without loose in image resolution. The vertical optic lens shift reduces this
value.

The Lens Memory Save menu give you the possibility to store ten different
configuration of Zoom & Focus & Image Shift. Similarly, in the Lens Memory Load
menu there are ten different recall configurations: they are disabled until you will
saved one. The number of enabled memories, in the Load menu, corresponding to the
number of filled memories in the Save menu.

The F1, F2 and F3 buttons function, in the RC, have the possibility to recall one of the
first three Zoom & Focus & Image Shift memories.

Save and Load the Lens Memories

Follow the procedure below:

1) Install the projector (see the installation chapter) in your room.

2) Adjust the Zoom and Focus to match your screen format at 2,35:1.

3) Store this configuration, by the Lens Memory Save menu, in one of ten possible
positions.

4) Display a source format at 16:9.

5) Adjust the Zoom, Focus and Image Shift, in order to match your vertical screen
dimensions, and center it.

6) Store this new configuration, by the Lens Memory Save menu, in a different
position compared to previous.

7) Recall the two lens memories by the Lens Memory Load menu, or by one of
Remote Control buttons function (if programmed), or by an RS232 command.
