20 LES 600 OPERATING INSTRUCTIONS
• Check to confirm speaker wires are in the correct wire
terminals on the back of the Receiver/Amplifier and confirm
that the speaker switch for that speaker output is in the ON
position. Black (or black stripe) to black terminal. White or
gray wire to red terminal.
Transmitter Care
• Cleaning the microphone jack and battery contacts will
help ensure that your system gives you years of reliable
service. We recommend using “deoxidizer” or contact
cleaner every 2 or 3 months.
Battery Maintenance & Care
• Battery should fit snugly against the contact points inside
the battery compartment.
• Batteries are to be charged each night and over the
weekends. They should not be left charging over the
summer or during Christmas and Spring Breaks. Prior to
extended breaks, systems should be fully charged and
batteries removed from Transmitters. After extended breaks,
reinstall batteries and recharge batteries before using again.
• Battery removal in the Handheld Transmitter is achieved
by sliding down the battery cover and lifting the black
“ribbon” to pop the first battery out. Then pull the white
plastic battery guide towards the bottom of the Transmitter
while guiding the remaining two batteries out of the battery
compartment. Slide the white guide back into the Transmit-
ter to install batteries.
If you have gone through this checklist and are still having
