Switches ON/OFF at one end of BU1.5V line which is separated into 2 direc-

tions.

Uses output voltage as D1.5V.

Lowers signal level by about 1.2V so that Lo level signal that turns the regula-

tor ON/OFF surely becomes Lo judgment level of the regulator SW.

Prevents reverse bias which is applied to laser.

The output voltage in which the power supply that diverges from the BU1.5V

line is turned on and off is used as D1.5V.

The output voltage in which the power supply that diverges from the BU3.3V

line is turned on and off is used as D3.3V.

Because the detection logic of LOE/LIM_SW is different in the mechanism

μ-com and the system μ-com, the logic to the mechanism μ-com side is

reversed.

Prevents reverse bias which is applied to laser.

Laser destruction prevention.

The potential difference between DGND and AGND is absorbed, and the mal-

function by static electricity is prevented.

How to transfer to the mode

●

Perform the reset operation while pressing and holding [B.BOOST] + [SEARCH] to transfer to the test mode.

How to clear the mode

●

Clear the test mode with the conditions below.

• Reset

• Momentary power down detection

• ACC OFF operation

• POWER OFF operation

Limitation/ special remarks in the mode

●

• When detecting the disconnection of the oscillator for sub-clock, all lights ON display ﬂ ashes.

• When the unit starts with the test mode, change the LINE MUTE inhibit time from 10 seconds to 1 second.

• In the test mode, do not write serial with the serial write jig.

• In the test mode, the DC error detection information is not written in Data Flash even if the DC error detection is performed.

• DEMO mode shall not operate in the test mode. Also, when the source is STANDBY, do not display DEMO ON/OFF switching

items in the FUNCTION.

• DISC forced load operation prohibited in the test mode.

DPX304/DPX308U/DPX404U DPX-MP3120/U5120/U5120S

TEST MODE

• In the test mode, even if the prescribed period of time elapses, the backup memory items are not written in save area (Data

Flash/ E2PROM).
