A symbol "" in the key column indicates that the key should be pressed and held for 1 second or longer.
How to enter the test mode
Procedure Press and hold the [1] key and [3] key and reset. Note While " " is displayed, power can be turned ON for only 30 minutes. (KDC-W3537AY/W3537GY/W4037Y only)
All lamps blink when it is detected that the sub-clock resonator is disconnected. Do not display "CODE_OFF", "CODE_ON" or "CODE_NG" when Power is ON. When having started up in the test mode, change the LINE MUTE inhibition time from 10 seconds to 1 second. When operating in the test mode, even if a DC offset error occurs, detection information is not written in the E2PROM. When operating in the test mode, CD mechanism error log information clear mode, and DC offset error detection information clear mode, do not perform DEMO mode operations. Also, do not display DEMO ON/OFF option items in the MENU in STANDBY source in the above modes. Forced disc ejection is prohibited in the test mode.

ROM data transfer
When replacing front-end (A1), this function is used to transfer E2PROM data (ROM correction, security and other data) to front-end (A1) to E2PROM of to mother unit (X34-), used for saving data, and, after completing replacement of front-end (A1), to recover data from the E2PROM of the mother unit (X34-), and for saving data to the new front-end (A1). Refer to "ROM data transfer processes" on the next page for details on frontend (A1) replacement procedures and on the data to be transferred. Procedure While pressing and holding [1] key and [3] keys, reset-start Press [B.BOOST] key (MENU) Press [ ] key or [ ] key

ROM DATA TRANSFER PROCESSES
When replacing front-end (A1) of mother unit (X34-), or when adding or replacing ROM correction (program correction with ROM IC (IC10)), the following activities are required.
Operation procedure
Operation procedure is different depending on the conditions. Proceed with the appropriate operation procedure depending on the specific condition.
Overview
When replacing front-end (A1) in the model where ROM correction and security data have been written into E2PROM, included in the front-end (A1) pack, the transfer function of the E2PROM data itself in the replaced front-end (A1) is required. This function in the above system configuration is used to allow for complete replacement of the front-end at any service center. 1. In case of replacing front-end (A1) without an applicable ROM correction. 2. In case of replacing front-end (A1) with an applicable ROM correction. 3. In case of applying new ROM correction at the same time when front-end (A1) is replaced. (No ROM correction has been carried out.)
q Mother unit (X34-) FRONTEND (A1) E2PROM SYSTEM µ-COM (IC1)
Overview of specifications
Procedures for replacement are as follows: To install the E2PROM to the mother unit (X34-), and replace front-end (A1) with new front-end after copying the data in the E2PROM (such as ROM correction data and other data) in the front-end (A1) to the mother unit (X34-) by operating the system, and then copy the data (such as ROM correction data and other data) into the mother unit to the E2PROM of the front-end (A1), operating the main body. Tuner adjustment data was inserted during the tuner pack manufacturing, and data will not be transferred because frontend (A1) is built-in. In addition, tuner adjustment data for new front-end (A1) is supplied as a service part in which data was inserted.

· DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.
CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list). Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.
