An analyst with Morgan Keegan & Co. Inc. downgraded Symbol Technologies Inc. Tuesday morning after a regulatory filing made clear that the pending acquisition by Motorola Inc. will proceed as planned.

Tavis McCourt, who covers technology companies for the Memphis- based investment bank, said in a research note that he had kept an "outperform" rating on Symbol on the "potential, although unlikely" chance that another suitor would top Motorola's $15-per-share bid for Symbol.
