Text is displayed for the first 50 track only and will not be displayed from the 51st track onwards. Do not suspect a fault in this case. In some cases, some special characters will not be displayed and may be replaced by other characters. Do not suspect a fault in this case. Cold Reset The cold reset clears all data including preset data stored in the RAM to initial conditions. Execute this mode when returning the set to the customer. Procedure : 1. When the power ON, press the ?/1 button (TA) while pressing the TUNING MODE button (ST) and ML buttons (CDP) together. 2. “COLD RESET” is displayed on the fluorescent indicator tube and reset is executed. Hot Reset This mode reset the preset data kept in the memory. The hot reset mode functions same as if the power cord is plugged in and out. Procedure : 1. When the power ON, press the ?/1 button (TA) while pressing the TUNING MODE button (ST) and lm buttons (CDP) together. 2. Turn off the unit and reset is executed. GC Test Mode Procedure : 1. When the power ON, press the ?/1 button (TA) while pressing the TUNING MODE button (ST) and PLAY MODE buttons (CDP) together. 2. LCD are all turned on. 3. Press TUNING MODE button (ST) to enter the model destination indecation mode. “SP55 CE2” or “SP55 ASIA2” appears. 4.Every pressing of TUNING MODE button (ST) changes the display in the following order. MC Version t CD Version t ST Version t TC Version t TA Version t TM Version t model destination display. 5.Press DISPLAY button (ST) and the date appears as “ 00615a ” Every pressing of DISPLAY button (ST) changes the display in the Version display and model destination display. 6. Press TUNER/BAND button (ST) to enter the key check mode. 7. In the key check mode, the fluorescent indicator tube displays “Key 0 Vol 0”. Each time a button is pressed, “Key” value increases. However, once a button is pressed, it is no longer taken into account. “Vol” Value increases like “1, 2, 3 .” if rotating VOLUME knob (TA) in the clockwise direction, or decreases like “0, 9, 8 .” if rotating in the counterclockwise diretion. 8. To exit from this mode, disconnect the power cord. This unit cannot be repaired by itself. When repairing, connect the whole system except for the speaker. 12 SECTION 4 EXPLODED VIEW 4-1.
