Parts: MD-Mechanism Type: MT-MZR55-161, Optical Pick-up Type: KMS-280A

Mis-features: Contrary to what is stated in the manual, the battery cannot be recharged while the unit is in use. When the unit is in the ``stopped'' state, pressing the stop button will start the battery charging. In manual recording level mode, unit must be paused to change the level setting (as with all Sony portables).

Notes: The MZ-R55's remote can be used with the MZ-R50, but in this case the backlight is inoperative (only the MZ-R55 emits the command codes needed to control the backlight). The MZ-R55 remote is completely interchangeable with the MZ-R37 remote. -Gerald Tomyn

Tips: Take special care to close the rechargeable battery compartment hatch carefully and completely; the plastic tabs at the corners have been known to break when they are not grasped completely by the metal hook edge inside the player.

Problems: Hoshing Kwong describes a circuit board fix for the Sony MZ-R55 self recording-start problem.
