Power On and Battery Charge Indicator
Press and hold the button until the red LED comes on, then release the button. The red LED will then
blink in a pattern that indicates battery charge state. In general, the shorter and slower the LED blinks
the more charged, and less in need of charge, the glasses are.
Blink activity after power-on blink
Three long blinks after initial power on

Six medium blinks after initial power on

Twelve fast blinks after initial power on

If the glasses are powered off but charging, the LED will display a slow "heartbeat" signal when the
glasses are fully charged.
Powering Off
The glasses must be powered off using the Auto Power Off method.
Auto Power Off
If the glasses do not detect an emitter, the LED will blink on and off once per second for five minutes
and the Optoma 3D-RF Glasses will auto power off. If the emitter is activated (the emitter is only active
when then TV is in 3D mode) before the five minute period expires, the glasses will stop blinking and
remain on. If the glasses auto power off, the power on button press is required to turn them back on.
Pairing to an emitter
With the device off, press and hold the power button. After 1-2 seconds the red LED will come on.
(Normally, you would release the button at this point to power on the glasses.) Do not release the
button after the red LED comes on, keep holding down the button. After about 10 seconds of the LED
on solid the LED will start to pulse with the same "heartbeat" pattern used by the emitter in pairing
mode. (When you see the heartbeat pattern, you must release the button within 20 seconds or the
device will go into Restore Factory Defaults mode.)
The glasses will stay in pairing mode until they successfully pair with an emitter, or until one minute
expires. While in pairing mode, the LED will display the "heartbeat" pattern. If the glasses find an
emitter in pairing mode, then the glasses will pair with the emitter and resume normal operation as
described in Power On and Battery Charge Indicator. If an emitter is not found in pairing mode, the

remaining.
Battery is 10% or more charged, 4 hours or more remaining
Battery charge is less than 10% or less, risk of glasses
needing to be wired to charger before end of a long movie or
