CLN

Cln appears on the display when a cassette is inserted and the cassette player needs to be cleaned. The player will still play tapes. Clean the player in order to prevent damage to the tape and the player. Refer to Cleaning Tape Head and Capstan, Cassette Cleaning Service and Repair

After you clean the tape player, press and hold EJECT for 5 seconds. The radio will display four dashes to show that the clean feature is reset.
