Dynatronics Laser Corp. said net income for the first fiscal quarter of 1991 ended Sept. 30 was $81,544, down from $106,111 for the same period last year.

Sales for the three months were $1.55 million, down from $1.67 million for the first quarter last year."While the education process for our new products has taken longer than we had anticipated, management is optimistic about recent penetration with our existing product line into new medical markets," said Kelvyn H. Cullimore, president.

"This expansion and penetration should boost both revenues and profits for the fiscal year 1991."

Dynatronics designs, manufactures and markets advanced-technology medical devices.
