3.Safety instruction

1. General safety

Safety regulations require that during a repair:

. Connect the unit to the mains via an isolation transformer.

. Replace safety components indicated by the symbol

by components identical to the original ones. Any

only

other component substitution (other than original type)

may increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, you must

return the unit in its original condition. Pay, in particular,

attention to the following points:

. Route the wires/cables correctly, and fix them with the

mounted cable clamps.

. Check the insulation of the mains lead for external

damage.

. Check the electrical DC resistance between the mains

plug and the secondary side:

1) Unplug the mains cord, and connect a wire between

the two pins of the mains plug.

2) Set the mains switch the “on” position (keep the

mains cord unplug).

3) Measure the resistance value between the mains

plug and the front panel, controls, and chassis

bottom.

4) Repair or correct unit when the resistance

measurement is less than 1M

5) Ve

rify this, before you return the unit to the

customer/user (ref. UL-standard no. 1492).

6) Switch the unit “off”, and remove the wire between

the two pins of the mains plug.

¡

.

2.Laser safety

his unit employs a laser. Only qualified service personnel

T

,

may remove the cover, or attempt to service this device

(due to possible eye injury).

Laser device unit

Type : Semiconductor laser GaAlAs

Wavelength : 650nm (DVD)

: 780nm (VCD/CD)

Output power : 7mW (DVD)

: 10mW (DVD /CD)

Beam divergence: 60 degree

Note: Use of controls or adjustments or performance of

procedure other than those specified herein, may result in

hazardous radiation exposure. Avoid direct exposure to

beam.

11. Software upgrade & procedure to restore product setting

eset to defaults：

1. R

n, long press “Stop” button quickly, it will display the software version. Then short press the

Plug i
“Stop” button, it will display “Reset”, and access “STANDBY” in a while. When it displays “--”,
it has been reset to defaults.

2.Check the software version:

Plug

in, long press the “STOP” button quickly, it will display the software version.

3.Software-upgrade method:

the updated software(boot.ali and nemo.bin) into USB, insert it into the CD MINI, you

Copy
will hear “Do” sound for two times, which means it starts to upgrade. About 40 seconds later, you
will keep hearing “Do” sound which means the upgrade is done. At this time you can unplug the
power and remove the USB. Noted: Should not blackout during the upgrade, otherwise the
machine will crash (it can not start up and the display shows nothing.). After the crash, the only
solution is to remove the FLASH IC (U4, EN25F20), rewrite the software on programmer or
directly replace a new FLASH with effective program.
