How to enter the test mode
Procedure Note
Press and hold the [1] key and [3] key and reset.
• All lamps blink when it is detected that the sub-clock resonator is disconnected.
• 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, the serial number shall not be written with the serial number writing-in tool.
• 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.

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
front-end (A1) replacement procedures and on the data to be transferred.

ROM DATA TRANSFER PROCESSES
Overview
When replacing front-end (A1) in the model where ROM cor-
rection 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 re-
quired.
This function in the above system configuration is used to
allow for complete replacement of the front-end at any ser-
vice center.
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.
