6 LES 600 OPERATING INSTRUCTIONS
4 NiMH batteries will usually maintain their charge for a full
day of normal classroom use. Always switch the Transmitter
OFF when not in use (lunch hour, quiet times, etc.).
Should the batteries in the Transmitter need to be changed,
open the lower plastic cover by pressing the ribbed
portions on both sides of the cover (located near the center
of the Transmitter) towards each other. At the same time,
pull forward on the cover, rotating it on the hinges located
at the bottom of the cover. Insert the new batteries (paying
attention to the + and - as indicated inside the case).
Rotate the cover back toward the Transmitter center and
snap it back into a locked position.
5 To attach the Microphone to the Transmitter, align the
microphone plug over the belt-pack connector jack. With
the black plastic dot facing forward, gently guide the con-
nector into the jack. Be sure not to put undue stress on the
wire or connector. To remove the Microphone, simply press
inwards on the black plastic dot located on the microphone
connector. Holding the connector rather than pulling on the
wire, gently remove the connector from the Transmitter jack.
6 A switch on the top of the Transmitter case activates the
Transmitter. When turned ON, the red POWER indicator
will flash briefly.If the indicator remains lit continuously,
the battery charge is getting too low and must be recharged.
When the Transmitter power is turned
OFF, the microphone audio to the
Receiver is automatically muted.
Note There is a delay
of about one-second from
the time the Transmitter
switch is turned ON until
the Receiver sends a signal
to the Amplifier. This is
normal.
