Motorola president Robert Growney called the performance of its wireless handset business "unacceptable", and reported a big slowdown in orders across its business lines.
However he claimed that the weakness is the result of "current industry-wide conditions and not a loss in [Motorola's] market share".
The forecast follows a number of profit warnings from US technology firms, signalling a slowdown which Growney said is "bleeding very quickly into Europe" .
