FrontRow Systems Troubleshooting Check batteries • Rechargeables will only last 1 to 2 school years. • Front Row products require nickel metal hydride (NiMH) batteries. They do not create a “memory” so they can be charged each night. • Charging alkaline (non-rechargeable) batteries is our #1 repair cause. • Fresh batteries are the easiest troubleshooting tool. No sound • Check power and batteries. Is green light on? • Batteries dead, not charged, placed the wrong way? • The “toGo” tower battery may need to be replaced every 3 years. • Is the transmitter turned on? Receiver on? Volume too low? • Do the transmitter and receiver channels match? • Does the mic or transmitter have a “mute” switch? Is it on? • Use the mic with another working system to test. Interference/Static • Microphones are our #1 problem source for static or buzzing. • Intermittent static, loud crackle or popping sounds are usually a broken mic jack • Is there a new installation in the school interfering? • Are channels A and B both on, but one is not in use? • Two transmitters on the same or similar channels. Change channel. • Does it make a sound when you walk by something specific? • How does it sound with the lights out? Computer off? • Use mic from another working system to test. • Is the receiver antenna attached? • Batteries could be old, low or missing. • Is the antenna missing? Feedback • Is the tone set too high? Is the volume too high? • Is the mic too far from the teacher’s mouth? This causes increased volume. • Are the speakers (Pro Digital) installed too low? They should be above 6 feet and angle down at 45 degrees. • Lapel mics are more susceptible to feedback, which is why the overthe-ear boom mic is recommended.
