CrystalEyes is designed to be worn with or without prescription eyewear with no adjustment needed. A compatible stereo
computer graphics or video system must be available to check the operation of the eyewear. Each pair of CrystalEyes eyewear
includes two fresh batteries, which are installed at the factory. To activate the eyewear, unfold the temple pieces; to turn off the

eyewear, fold the temple pieces. Always fold the eyewear when not in use to maximize the battery life.

Installing the StereoGraphics Emitter

StereoGraphics CrystalEyes requires the use of an infrared emitter in order to synchronize the eyewear in conjunction with the left
and right image sequence on screen. The infrared receiver (located in the center of the eyewear) must be in line of sight and in
range of the emitter for successful operation of CrystalEyes. Please consult the documentation accompanying your emitter for
installation and operation details. For best results in using CrystalEyes with standard workstation
displays, set the emitter slightly behind the top edge of the monitor, as shown in Figure 1. In addition:

INSTALLATION & SETUP

Figure 1. Display and Emitter

• For EPRO, ESGI and ELR emitters, make sure the emitter is switched to the ON
position. Depending on the emitter range needed, switch the emitter to either the high
or low setting.

• The ENT emitter will switch on and off automatically whenever a sync signal is
presented by the graphics card.

• Users of the EPC-2 must switch the emitter from BYPASS to STEREO MODE and
set the emitter range separately.

Optional add-on Nosepiece

The new optional nosepiece has been designed to give a better fit for people with smaller noses or who wear prescription eyeglasses
and where the CrystalEyes do not rest comfortably on the nose bridge.

The nosepiece simply ‘sticks on’ over the current built-in nosepiece. To attach the nosepiece, remove the backing tape to the
adhesive strip on the add-on nosepiece and slide the nosepiece into position with the flange facing out. Press into place until the
adhesive ‘sticks’ (approximately 2 seconds).

Battery Indicator -- New for CrystalEyes 3

The battery indicator light is positioned inside the CrystalEyes frame above the right lens. The LED indicator will illuminate for
approximately 2 seconds only when the eyewear is switched on (by opening the right temple). After approximately 2 seconds the
LED will switch off and remain off until the temple reactivates the on/off switch.

Indicator light: ON for 2 seconds: battery OK

Flashing for 2 seconds: batteries should be replaced
OFF: batteries are dead or on/off switch reactivated within 2 seconds;

replace batteries.

Note: If temples are closed and re-opened within 4 seconds, the battery indicator will not illuminate. Wait 4 seconds to check the battery.

MAINTENANCE

As with any eyewear, take care to prevent scratching the lenses and protect the electronic circuits within the eyewear from damage by
excessive moisture or immersion in liquids.

Battery Replacement

CrystalEyes uses two 3-volt lithium/manganese dioxide (CR 2032) batteries.
To replace the batteries, first fold the temple pieces of the eyewear. Locate the battery holder at

the hinge-point of the left temple piece. Using a paper clip or ballpoint pen for help (as shown
in Figure 2), swing the battery holder out from the eyewear and remove the existing batteries,
noting their orientation.
Place both fresh batteries into the battery holder making sure that the positive (+) sides of each
battery face in opposite directions, as indicated. Each position will accept its battery in only
one orientation.

Follow the installation instructions located inside the battery holder.
If the holder will not close easily, do not force it! Check the batteries to make certain they are seated in the holder and oriented in

opposite directions. If the battery holder will not close, reverse both batteries and try again.

Cleaning

CrystalEyes lenses have hard-coated plastic surfaces and if cared for properly will remain in good condition for many years. Using
a soft chamois cloth or lens tissue intended for plastic lenses, gently wipe the lens surface.

Warning: Do not immerse the eyewear in water or liquid. Avoid spraying cleaner directly onto your
eyewear. The use of excess moisture can destroy the electronic circuits within the eyewear and may
invalidate your warranty.
