Exhibit 99.1

Press Release

RELM Wireless Reaches Agreement to Settle Lawsuit

WEST MELBOURNE, Fla, March 10, 2004 - RELM Wireless Corporation (OTC Bulletin Board: RELM) today announced it has reached an agreement to settle an 11-year-old lawsuit that was originally filed against its predecessor, Adage Incorporated, in 1993. Under the terms of the agreement, the Company will pay to the plaintiff cash totaling $120,000 and issue to the plaintiff 6,452 shares of restricted RELM common stock valued at the closing price on March 1, 2004. This agreement is the result of recent pretrial discussions. As previously announced, this matter relates to the note of a former affiliate totaling $1.7 million plus $2.6 million in alleged accrued interest. The case had been scheduled for jury trial on March 22, 2004. The settlement will eliminate the potential for an unfavorable verdict in the total amount of the note, accrued interest and legal fees. The settlement is subject to the execution by both parties of a written agreement and release.  

Under generally accepted accounting principles this settlement must be included in the Company’s results for the fourth quarter of 2003 rather than the first quarter of 2004. Therefore, in accordance with GAAP, the Company has recognized an additional expense related to this matter totaling $140,000. Including the impact of this agreement, net income for the fourth quarter ended December 31, 2003 was $832,000, or $0.08 per diluted share. For the year ended December 31, 2003, including the impact of this agreement, net income was $868,000, or $0.09 per diluted share. As previously reported, net income for the fourth quarter ended December 31, 2003 was $972,000, or $0.09 per diluted share and net income for the year ended December 31, 2003 was $1,008,000, or $0.11 per diluted share.

RELM President and CEO David P. Storey commented, “We are pleased to settle this matter for little more than anticipated litigation costs and eliminate the possibility, however remote, of an unfavorable verdict in a jury trial. This was the last in a series of legacy issues inherited years ago from RELM’s predecessor that are completely unrelated to the operational excellence achieved in our present core business. With this agreement, the last of these old matters has finally been settled, and we can move forward completely focused on our land mobile radio business.”

RELM Chairman George N. Benjamin III added, “The final resolution of this old claim removes the last distraction from the past, allowing our management and board to give its full attention to the company’s strategic initiatives and increasing shareholder value. While RELM struggled in recent years to reengineer its operations and develop next-generation digital product technology, these claims still lingered and impacted the company’s progress. Now all these matters are resolved, and the company’s recent string of new product introductions, technical approvals and federal contracts opens the way to a bright future without any of the old baggage.”  

For more than 55 years, RELM Wireless Corp. has manufactured and marketed high-specification two-way communications equipment for use by public safety professionals and government agencies, as well as business-band radios for use in a wide range of commercial and industrial applications. Revolutionary advances include new low-cost digital portable two-way radios compliant with APCO Project 25 technical specifications.
