  • Page 12 SD-SH111H Notes for handling the mechanism unit Since the pickup semiconductor laser can easily damaged by the static electricity, handle the mechanism unit with care. To prevent damage by the static electricity during transportation, the LD terminals are short-circuited at 2 points on the PWB.

  • Page 14 SD-SH111H 2. DVD Test Mode Outline: The key code of the test mode 1 is transmitted to the DVD unit to start up the test mode. Hereafter, the system microcomputer only sends the key code to the DVD unit. Although operations of the main unit can be commenced in the same manner as the DVD/CD functions, nothing has to be controlled except for monitor output.
  • Page 15 SD-SH111H Supplementary notes: 1. The DVD/CD cover cannot be opened or closed (loading or unloading discs) in this test mode. After loading a disc, turn the power off to enter this test mode. 2. Operations of keys unrelated to the DVD operations are not accepted except for the POWER key. Therefore, you cannot switch functions, control volume, or control DSP, etc.
  • Page 16 SD-SH111H 4. KEY Test Mode Outline: This is to check that the system microcomputer properly acknowledges the key operations on the main unit. Operation: In this test mode, the power is supplied only for the display, and all the FL indications are turned off as in the test menu mode.
  • Page 17 SD-SH111H 7. TUNER Test Mode Outline: Start up the unit as set to the TUNER function in the same procedure as the normal operation. Operations and indication after startup are identical with the normal operations. However, what is different is that the frequencies as shown in the table below are set to the tuner preset memory in advance.
