What do the different colored lights on the front of the device mean?

• Black/off means -  Unit is disconnected or camera is inactive

• Red means – Camera may be in use, but test has not yet begun and the clear arm holding the spheroid is not fully inserted*.

• Yellow means – Camera is in use, test has begun, but the clear arm holding the spheroid is not fully inserted*.

• Green means – Camera is active and the clear arm is fully inserted.

*There is a line etched into the clear arm that will be flush with the top of the camera base when the arm is fully inserted.  If the light is red or yellow, push down firmly (but not enough to break the plastic) on the clear arm until the light either turns off, or becomes green.

Thank you,
