Minnetonka, MN ---- August 9, 2011----- Communications Systems, Inc. (NASDAQ: JCS) today reported financial results for its second quarter and six months ended June 30, 2011.

William G. Schultz, President and CEO, commented: “Our outstanding quarterly results were bolstered by the previously announced large orders received by our Transition Networks’ business unit early this year. This one- time project contributed $19.4 million in revenue for the quarter. Transition Networks also received additional orders from the same large customer for $1.3 million in June and $4.7 million in July. Orders received from this customer totaled $27.9 million for the six months ended June 30, 2011. While pleased with our quarterly results, apart from increased sales to this customer, we saw a decrease in some of the traditional business in our two larger business units compared to the same quarter last year.”
