LR-500 Wall Transformer Operation

The LR-500 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-500 marked “PWR/CHG” and plug the wall transformer into a grounded AC outlet.

You do not need to have batteries installed in the LR-500 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 9. Please review the information on page 19 for important information regarding battery type and charging.

The LA-202 wall transformer plugs into the side of your portable transmitter or receiver.
