Narrative:

On gear retraction after takeoff we got an amber 'gear' light and a 'gear disagree' EICAS message. Per the QRH; we observed the gear extended speed limit of 270 KIAS; although the actual gear position was unknown. Page one of the landing chapter of the aom states that the illumination of an amber gear light and an EICAS message is an 'abnormal landing gear condition' with no further guidance. We elected to see if the gear could be safely lowered for a '3 green' indication which we were able to do. We declared an emergency; burned down to max landing weight and landed uneventfully at our departure airport.
