LR-400 Wall Transformer Operation
The LR-400 will operate normally when connected to a wall transformer. Use Listen part number
LA-202, available from any Listen dealer. Connect the wall transformer to the jack on the side of
the LR-400 marked “PWR/CHG” and plug the wall transformer into a grounded AC outlet.
You do not need to have batteries installed in the
LR-400 to operate it with a wall transformer.
NOTE: If batteries are in the unit ensure that the
battery selection switch is set properly as shown on page
29. Please review the information on page 38 for
important information regarding battery type and
charging.
The LA-202 wall transformer
plugs into the side of your
portable transmitter or receiver.
