LR-300 Wall Transformer Operation
The LR-300 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-300 marked “PWR/CHG” and plug the wall transformer into a grounded
AC outlet.
You do not need to have batteries installed in the LR-300 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 39. Please review the information on page 42 for important information
regarding battery type and charging.
