• Turn the body-pack Transmitter and/or the Hand-held
Microphone OFF whenever leaving the classroom.
• Recharge batteries each night. Operating time (actual usage) for
the Transmitter when using the rechargeable batteries should be
more than adequate for a typical school day. Your rechargeable
batteries should last for a normal school year if properly cared for.
• Do not recharge disposable batteries as they can overheat and
explode, creating a significant hazard. This may also damage
the Battery Charger or Transmitter, voiding the warranty.
• Try to avoid bumping or dropping the Microphone and/or
Transmitter. Treat cords (particularly near the attachments),
microphones, and batteries gently. These are usually the areas
that tend to malfunction first from misuse.
• Avoid winding the Microphone cable around the body-pack
Transmitter. This can damage or break the connecting cord,
producing static or noise in the FM system.
• Avoid blowing into the microphone when testing it. Instead, rub
fingers over the foam microphone cover, or snap fingers near the
microphone. Or conduct a consonant test by saying “ah, bah, s,
sh, th”, etc. These consonant sounds represent some of the softer
frequency ranges of speech and if they can be heard and distin-
guished, your equipment is working effectively.
• The Receiver/Amplifier has two auxiliary sound source input
jacks that may be used to amplify additional complimentary
audio from a VCR, CD-ROM, computer, cassette tape player,
etc., with a simple connecting cable (not included).
