Item List In Test Mode - Sony DWT-B30 Service Manual

1-5. Item List in Test Mode

The item list in the test mode used for operation confirmation is described below. To enter each item,
hold down the [SET] button. The setting of each item can be switched using [+] and [_] buttons. There
are items in which the change in setting brings a violation of the law. For the item whose change is
prohibited, therefore, do not change the setting. Turn on the power again when you changed the setting
incorrectly. The change in setting may be able to be recovered.
Entering the test mode
1. Turn on the power of this unit.
2. Move a menu to VERSION.
3. Hold down the [SET] button for two seconds or more.
4. Press the [+], [_], and [+] buttons sequentially.
5. Lastly, hold down the [_] button for two seconds or more.
Exiting the test mode
1. Turn off the power of this unit.

Function
Displays the firmware version of CPU (IC402) on the DPR-396 board.
Displays the firmware version of FPGA (IC201) on the DPR-396 board.
Displays the firmware version of remote CPU (IC2000) on the RM-215 board.
Displays the version of the channel plan built in EEPROM (IC813) on the
TX-172 board.
Displays the serial number of this unit.
Sets the destination of the RF circuit. Change is prohibited.
Not used for maintenance service.
Changes the GAIN of the amplifier circuit of the RF circuit per frequency. The
value cannot be changed. In the service, the transmission frequency can be
changed by moving the screen to B (C), B (L) and B (H) used for the setting
of frequency during the measurement of RF.
The changed status of the TX-172 board is written in EEPROM (IC813).
Notice that the status cannot be recovered when it is written incorrectly.
Change is prohibited. Not used for maintenance service.
The remote mode can be changed. Not used for maintenance service.
CH used for pairing can be changed. Not used for maintenance service.
Displays the remote control ID of this unit.
Displays the remote control ID of a pairing partner.
This is used for design and investigation. Not used for maintenance service.

This is used for design and investigation. Not used for maintenance service.
This is used for design and investigation. Not used for maintenance service.
IQ DAC (IC300) on the DPR-396 board can be put into the SLEEP state.
In the SLEEP state, a non-modulated signal is output from the RF circuit.
Used during RF frequency measurement.
This is used for design and investigation. Not used for maintenance service.
Lights up all dots of the organic EL display.
All lights during ALL LIGHT setting.
The transmit frequency of the RF circuit can be changed in units of 6 MHz.
Not used for maintenance service.
