ese helpful suggestions are provided
to maximize the successful use of your
new 705iR Portable Infrared Wireless
Amplification System.
• Speak in a natural voice. A normal
conversational speech level will provide
an adequate signal. It is not necessary to
increase the intensity of your voice—the
amplification system provides adequate
amplification (approximately 5 - 10 dB)
above ambient room noises.
• Avoid wearing jewelry that may rub or
bump against the microphone.
• Turn the LightMic OFF during private
conversations with a student, parent, or
other classroom visitor. You can also
cover the LED lens on top of the
LightMic to block the signal.
• Recharge batteries each night. When
recharged nightly, operating time
(actual usage) for the transmitters will
last through a typical school day. Your
rechargeable batteries will last for a
normal school year when cared
for properly.
• Do not use or attempt to recharge
disposable alkaline batteries—they will
overheat and expand, creating a signifi-
cant hazard and damaging the transmit-
ter. (is type of damage is not covered
under warranty.)
• Connecting the 705iR into a standard
electrical socket using the supplied 16 V
DC power supply/charger charges the
batteries. It can also be used as a direct
power source for the amplifier.
