- No sound is heard when the power is turned on.
- Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and
negative speaker connection wires are
"shorted", or if speaker systems with an impedance less than the indicated rated impedance of
the amplifier are used.
If this occurs, follow the procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.
Note:
When the protection circuitry functions, the unit will not operate unless the power is first turned
off and then on again.
6. Precaution of Laser Diode
CAUTION :
This product utilizes a laser. Invisible laser radiation is emitted from
the optical pick up lens when the unit is turned on.
Wavelength : 662nm(DVD)/785nm(VCD/CD)
Maximum output radiation power from pick up : 100
Laser radiation from pick up unit is safety level, but be sure the
followings:
1. Do not disassemble the optical pick up unit, since radiation from
exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pick up unit. It was
already adjusted.
3. Do not look at the focus lens using optical instruments.
4. Recommend not to look at pick up lens for a long time.
