CHAPTER 8 System Walk-Thru Now that you have successfully set up your RTS Wireless Intercom System and turned on any auxiliary equipment, you are ready to test the overall performance by walking the RTS system through the areas in which you will be using it. Before you begin your walk-thru, check the following: ❐ ❐ Beltpack Battery Check. Set microphone gain in both the beltpack(s) and the base station.
74 System Walk-Thru BTR-800, TR-800, TR-825
CHAPTER 9 Troubleshooting Reread the sections of this manual to make sure you have completed system set up properly PROBLEM If you are unable to solve the problem, contact the dealer from whom you purchased the system for assistance. SOLUTION DISTORTION - System’s audio quality seems distorted at medium to high input levels. Reduce microphone gain by adjusting microphone gain control. HISS - System seems to produce a “hiss” which is undesirable. Check the gain setting on all beltpacks and the base.

CHAPTER 10 Tech Tips Frequency Interaction Unfortunately, radio frequency (RF) channels cannot be randomly selected for use in radio devices. They must be selected to avoid know frequencies in use, FCC restrictions on the location of devices, and even interference between your own RF devices. The factory defined frequencies (Groups 01A-24) selected by RTS for this wireless system are chosen to minimize possible interference.
78 Tech Tips BTR-800, TR-800, TR-825
CHAPTER 11 Battery Information Improper battery selection, use, installation and care are the cause of numerous wireless system failures. Alkaline Batteries: Alkaline batteries such as Eveready’s ENERGIZER®1 and ENERGIZER INDUSTRIAL provide the most reliable operation in wireless transceivers. The use of low cost carbon-zinc batteries is NOT recommended. Nickel-Metal Hydride Batteries - These batteries can save you money in the long run, as they can be recharged.
