PRO-2009 (200-0109) Troubleshooting Faxback Doc. # 16759 The PRO-2009 is a ruggedly built electronic unit, with all parts conservatively rated. However, you should treat it with care; don't subject it to excessively rough handling. You will find it will give you long life if kept free from dirt and excessive humidity. The 9-volt Battery (used to maintain the program memory) should be replaced every 6 months. Use only an Alkaine type, such as Radio Shack's Catalog Number 23-553 (replace only while the AC line cord is connected). Problem Possible Cause Inoperative No power - check to see that unit is plugged into a working AC outlet. Will not scan Improper squelch setting - turn SQUELCH control clockwise to slightly past point where rushing sound ceases (while no signal is present). Scan locks - in on "Birdies" frequencies where no clear signal is present If none of these suggested remedies solves the problem, return your set to your nearby Radio Shack. It will be repaired by a qualified technician and you'll have it back ASAP! (LB/all-08/29/95)
