When Using Battery Power:
Charging the 705iR
a. Ensure the power switch (CH A POWER)
on top of the 705iR is turned off.
b. Plug the power supply/charger cable into
a standard AC outlet.
c. Plug the other end of the power supply/
charger into the DC power jack on
the back of 705iR. e LED above
the DC will glow red. A solid green LED
indicates the 705iR is fully charged.
d. Charge the batteries completely prior to
first use. Charging time can take as
long as 10 to 14 hours. When fully
charged, the circuit switches to a trickle
charge, which will not overcharge or
damage the batteries.
705iR Receiver/Amplifier
[ Positioning ]
e 705iR has a built-in speaker, which
should be directed toward the area of the
classroom where the students are sitting. e
unit can be placed on a table top or book
-
shelf at a height of 36 to 60 inches.
e ideal position in the classroom is cen
-
tered along the longest wall. However, due to
different classroom setups, this is not always
possible. Here is a quick guide to choosing
a location:
Best: Centered on the longest wall
Good: Centered on the short wall
Okay: In a corner
Avoid: Placing the unit directly in front of
a window.
[ Two Power Options: AC or Battery ]
e 705iR operates with battery power in
a portable application, or you can leave the
system connected to AC power for a more
permanent application.
When using AC power:
a. Plug the power supply into a standard
AC outlet.
b. Plug the other end of the power supply/
charger into the DC power jack.
c. Turn the CH A POWER on and set
an appropriate volume level. e 705iR
may be left on at all times when using
AC power.

If the 705iR will primarily be
used in a fixed location within
the classroom, LightSPEED
recommends using AC power.
If the 705iR will be moved within a
classroom or to different class-
rooms, battery-powered will provide
the most flexibility.
