    XL-505/505C,CP-505B TEST MODE The Test Mode for this microcomputer has two variations, namely "regular Test Mode" for adjustment and measurement and "self- diagnosis Test Mode" for self-judgment in final inspection of products. 1. Entering the Test Mode To enter the each Test Mode, press the POWER key, holding down the following two keys in the regular standby mode (power off state).
  • Page 12 XL-505/505C,CP-505B 2. Step 2 Mode When the PLAY key is pressed in the mode above, the laser lighting is turned on. In this state the laser is only turned on, and other operations are not performed. When the following operation key is pressed in this state, the following operation is performed.
  • Page 13 XL-505/505C,CP-505B 5. Step 5 Mode The tracking servo is turned on, groove is traced, mute is set to off, and playback is started. Even when the outermost periphery of disc is reached in playback mode, it does not stop. The LCD display indicates playback lapse time as in case of regular CD playback.
