A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.
Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!

Troubleshooting Guide
PROBLEM
No sound can be heard, or the volume is low.
POSSIBLE CAUSE
Attenuator is turned on. The fader or balance settings are set all the way to one side. The input/output wires or wiring harness are connected incorrectly. The cassette tape is bad. The values of Volume offset are low. Turn off Attenuator.
SOLUTION
Reset the fader or balance settings. Reconnect the input/output wires or the wiring harness correctly. See the section on "Connecting Wires to Terminals". Try playing another cassette tape. If works fine, the first tape was bad. Increase the values of Volume offset. (see p. 7) Press the Eject button.
The tape does not go in. / No sound can be heard even though the tape display is made. The sound quality is poor or distorted.
The car ignition was turned off during tape eject; or the tape was pulled out during loading, switching the mode to tape mode even though no tape is in. The tape head is dirty. One of the speaker wires is being pinched by a screw in the car. The speakers are not wired correctly.
Clean the tape head, referring to the section on "Cleaning the tape head" (see p. 4). Check the speaker wiring. Reconnect the speaker wires so that each output terminal is connected to a different speaker. The tape can only be removed within 10 minutes of the ACC switch being turned OFF. If more than 10 minutes has elapsed, turn the ACC switch ON again and press the Eject button.
Can�t remove tape.
The cause is that more than 10 minutes has elapsed since the vehicle ACC switch was turned OFF.
