LightSpeed Technologies 705iR - Manual (Page 13)

1. DC POWER INPUT JACK:
This input connects to the 16 V
AC/DC adaptor that comes with
the 705iR. The adaptor is used to
either charge the internal battery
pack or power the 705iR with
AC power.
2. EXTERNAL IR SENSOR JACK:
This jack is provided for connection
of an additional sensor (for larger or
odd-shaped rooms).
3. TRANSMITTER CHARGING
JACKS: This connector is used to
connect the charging cable to the
LightMic transmitter or the optional
HM-70 handheld microphone for
daily battery recharging.
4. CHARGING LED: This LED glows
red when the 705iR battery is charging
and glows green when fully charged.
4. BASS: This knob controls the low-
frequency sound of the 705iR.
5. AUX IN VOLUME: This knob
controls the volume level of an external
audio source that is plugged into the
AUX IN jack. An example would be a
computer, TV, VCR, CD or
cassette player.
6. AUX OUT VOLUME: This knob
controls the audio level going to
external equipment when plugged into
the AUX OUT jack. For example, a
personal FM transmitter or tape
recorder.
7. AUX INPUT JACK: This 3.5 mm
jack is used to connect to an external
audio source.
8. AUX OUTPUT JACK: This 3.5
mm jack provides a line-level audio
output that can be connected to a
personal FM system or tape recorder.
9. The LED light located above the
CH A POWER knob turns red
momentarily when the system power
is turned ON.
When a transmitter/microphone
set to Channel A is turned on, the
Channel A LED glows green to
indicate your transmitter’s signal is
being received by the amplifier.
0. The LED above CH B VOLUME
turns green to indicate a signal is

These 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. (This 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.
