Introduction

This document provides technical information for assisting Christie qualified technicians in the

servicing of the Cinema 4K-RGB projector.

Every effort has been made to make sure the information in this document is accurate and complete.

However, due to continuing research all information is subject to change without notice. Christie

assumes no responsibility for omissions or inaccuracies.

Site requirements

To safely install and operate the Cinema 4K-RGB projectors, the installation location must meet these

minimum requirements.

Physical operating environment

• Ambient temperature (operating) 10°C to 35°C (50°F to 95°F)

• Humidity (non-condensing) 10% to 80%

• Operating altitude 0 to 3000 meters (0 to 9843 feet)

External exhaust ducting

Sufficient ventilation is required around the projector to regulate the temperature of the internal laser

module. If necessary, air intake and exhaust HVAC ducts can be installed.

An exhaust duct is also available for purchase as an optional accessory (P/N: 163-102104-XX).

Instructions for installing the exhaust duct are included with the accessory part.

The installation site must provide an airflow 450 cubic feet per minute (CFM) at 1 to 1000 meters

elevation, and must accommodate a heat load of 4 kW.

For each additional 1000 meters above sea level, increase the airflow (CFM) value by 15%. If an

extraction duct is not used, the operating temperature range is restricted to 10°C to 25°C at a maximum

altitude of 3000 meters.

Permanent power connection

A 30 A maximum rated, certified wall circuit breaker is required. It must be part of the building and

easily accessible.

The projector must be connected to power using a hard-wired connection. The projector light source

requires the permanent AC connection to operate. There is also an available connector for an

uninterruptible power supply (UPS) to provide backup power for the projector electronics only.

Service setups

Understand the special internal hardware and software adjustments and related details that may

require the attention of a qualified service technician, whether done periodically or after a specific

module replacement.

Turning the projector on or off

Turn on the projector to display content, or turn off the projector to conserve energy or service the

projector.

To operate the projector, the circuit breakers must be in the ON position. If you are servicing the

projector or removing the protective covers, ensure that the MAIN and UPS circuit breakers are in the off

position.

• In the right toolbar, tap and hold Power.

If the light source is on when turning off the projector, the light source enters a ten-minute

cool-down period automatically.

Calibrating the Intelligent Lens System

On Cinema 4K-RGB projectors, the Intelligent Lens System (ILS) is activated by default.

Use the Auto Calibrate feature of the ILS to find and compensate for motor backlash, and to determine

the movement range for the currently installed lens.

1. In the left navigation menu, tap Image Settings > ILS File Setup.

2. From the ILS File list, select an available ILS file.

3. Tap Auto Calibrate.

4. Tap Continue.

The system performs the lens calibration.

Adjusting boresight

A boresight adjustment balances the tilt of the lens mount to compensate for screen-to-projector tilt.

Warning! If not avoided, the following could result in death or serious injury.

• Do not look directly into the lens when the light source is on. The extremely high brightness can

cause permanent eye damage.

• FIRE HAZARD! Keep hands, clothes, and all combustible material away from the concentrated

light beam of the projector.

Caution! If not avoided, the following could result in minor or moderate injury.

• This procedure must be performed by Christie qualified technicians.
