yellowblue Playing a Cassette Tape Your tape player is built to work best with tapes that are up to 30 to 45 minutes long on each side. Tapes longer than that are so thin they may not work well in this player. Once the tape is playing, use the knobs for VOLUME, BAL, FADE, BASS and TREB just as you do for the radio. REV: Press the SEEK left arrow to reverse the cassette tape. Press the SEEK right arrow to stop reversing the tape. FWD: Press the SEEK right arrow to advance the cassette tape. Press the SEEK left arrow to stop forwarding the tape. RECALL: Press this knob to switch tape sides. EJECT: Press this button to remove the tape or stop the tape and play the radio. CLN: If this message appears on the display, the cassette tape player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to the tapes and player. See "Care of Your Cassette Tape Player" in the Index. After you clean the player, press and hold EJECT for five seconds to reset the CLN indicator. The radio will display --- to show the indicator was reset. CD Adapter Kits It is possible to use a portable CD player adapter kit with your cassette tape player after activating the bypass feature on your tape player. To activate the bypass feature, use the following steps: 1. Turn the radio on. 2. Insert the adapter into the cassette slot. 3. Within five seconds, press and hold the REV and FWD buttons at the same time for three seconds. The tape symbol on the display will flash, showing that the cut tape detection feature is no longer active. This override routine will remain active until EJECT is pressed. 3-13
