There are transmitters on the microphones that transmit an infrared signal. To ensure optimal
performance, don’t cover or block the infrared transmitters. There must be a clear line of sight
between the microphones and the infrared sensor in order for the audio system to work
properly.
Microphone Chargers
If you use the included rechargeable batteries, you can
recharge the microphones by connecting a microphone charger
when the battery indicator light changes from green to red.
Fully charged batteries last approximately eight hours in the
teacher microphone. For the handheld student microphone,
fully charged batteries last approximately six hours when you
set it to High and approximately nine and a half hours when you
set it to Low. It takes approximately eight hours to fully recharge
the batteries.
Infrared Sensors
Infrared sensors detect microphone signals and send them to
the receiver. You can use either the infrared sensor on the
front of the receiver or the infrared sensor for the ceiling.
Ensure that there is a clear line of sight between the infrared
sensor and the infrared transmitter on the microphones.
Speakers
Your SMART Audio system comes with four wall or ceiling
speakers. The speakers mute if the signal from the
microphones is blocked or weak. This prevents unwanted
static and noise from occurring.
