THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR
;
Very Good! All the diagram are easy to read, and its complete.
;
This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!

7.1.2 Display of the Error History
� The type, date and time, and the number of occurrences of errors of the player can be recorded. Up to 8 types of errors can be recorded, and the number of occurrences can be counted up to 255 per error type. The date and time of the latest error is recorded per type. The date and time are based on the real-time clock built into the player. If the real-time clock has not been set or the setting is wrong, the dates and times of occurrence recorded will be those of the clock at that time. � An example of the error history display is shown below: Example of the error history display
How to display the error history
� Press the ESC, TV/LDP, then SIDE A keys on the remote control unit for service use, in that order.
How to clear the data of the error history
� While the error history is displayed, press the CLEAR key on the remote control unit for service use.
Display of power-on and playback duration
� The power-on duration and playback duration of the player can be recorded.
See below for how to display power-on and playback duration.
� Power-on duration: Accumulated power-on duration of the player. � Playback duration: Accumulated playback duration of the player. Duration is counted even in Pause and Still modes. This playback duration can be considered to be the spindle motor's duration of rotation or duration of use of the laser diode. Note: The power-on duration and playback duration are measured using the CPU clock of the player, so you should allow for about 2% error. Use these displays merely as a guide for servicing. � The data of the power-on and playback duration are not cleared if the player's software upgrade is downloaded from the dedicated web site. (As for the DVD-V700, the data of the power-on and playback duration are cleared when the player's software is upgraded.)
Date and time of occurrence of the latest error: 16:02, Nov. 5 Error count: Up to 255 ("FF"), in hexadecimal
11111337 11051602 00000000 00000000 00000000 00000000 00000000 0E 03 00 00 00 00 00
Error code
11 C3 00 00 00 00 00
How to display power-on and playback duration
� In the above example, two types of errors are recorded, and six other types of errors can be further recorded. In the above two cases (error codes "11" and "C3"), the error history will be recorded until their error count becomes "FF." � The data of the error history can be cleared if the number of error types reaches eight or the number of errors reaches 255. After the data of the error history are cleared, new errors can be recorded. (Cleared data of the error history cannot be restored. It is recommended that the data of the error history be written down before clearing.) � While pressing the DISPLAY key of the main unit, set the POWER switch to ON. (This is also explained in the Operating Manual.)
