Operation Modes of XPAND Pi Cinema 3D Glasses

Off Mode - In this mode the lenses appear green since they are not driven by 

the electronic circuit which remains powered and checks for a presence of a 

synchronization signal.

Warm-up Mode - Glasses enter Warm-up Mode from Off Mode when exposed to an 

IR signal. During Warm-up mode the lenses remain opaque for the entire Warm-up 

period which lasts about three seconds. At the end of Warm-up period the glasses 

transition into Clear Mode. 

Clear Mode - When in Run Mode, after the glasses lose a valid synchronization 

signal, they go into Clear Mode (both lenses appear clear). Glasses also transition into 

Clear Mode after Warm-up Mode. In Clear Mode both lenses remain open, so that the 

viewer can see normally through the glasses. The lenses remain open until a valid 

sync signal (re-)appears at which point they transition to Run Mode. If the glasses do 

not receive a valid signal in five minutes they go into Off Mode.

Run Mode - In this mode, the lenses open and close in sync with the projector to 

deliver 3D experience to the viewer.

Low-Battery Mode - The glasses check for low battery condition just before going 

to Off Mode and also before going to Warm-up Mode. If battery level is low, the 

lenses will begin blinking slowly (both lenses are closed and briefly flash open 

simultaneously once every two seconds) to indicate the Low-Battery condition and 

will prevent the glasses from going to Run Mode. The control circuit is designed so 

that the low battery condition does not appear during Run Mode when watching 3D 

content. The only possibility to exit Low-Battery Mode is by replacing the battery.

Before First Use

Brand new XPAND Pi Cinema 3D Glasses come with a pull-tag inserted between the 

battery and the battery contact on the circuit. The pull-tag ensures the battery is not 

empty when the glasses arrive. In order for the glasses to work the pull-tag must be 

removed. A simple pull will remove it from the glasses and they will be ready for 3D 

viewing. The pull tab is located on the left side of the glasses and is sticking out of 

the battery compartment.

Testing the Glasses

Testing of the glasses can be performed prior to handing them over to the user who 

will be watching 3D content. This is done by using the AT100 Active Glasses Tester. 

The AT100 is “ON” if the “ON/OFF” button is pressed and the red LED is lit. The 

AT100 is designed to generate a low intensity IR signal that, when passed within 2 

feet (60 cm) of the glasses, causes the lenses to flicker in response to the IR signal.
