7、ENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. The label on the right is applied on the rear panel. 1.This unit is a CLASS 1 LASER PRODUCT and employs a laser inside the cabinet. 2.To prevent the laser from being exposed, do not remove

8、 the cover. Refer servicing to qualified personnel. For British models Replacement and mounting of an AC plug on the power supply cord of this unit should be performed only by qualified service personnel. IMPORTANT The wires in the mains lead are coloured in accordance with the following code: As th

9、e colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black. The wire which i

10、s coloured brown must be connected to the terminal which is marked with the letter L or coloured red. IMPORTANT The plug is fitted with an appropriate fuse. If the fuse needs to be replaced, the replacement fuse must approved by ASTA or BSI to BS1362 and have the same ampere rating as that indicated

11、 on the plug. Check for the ASTA mark or the BSI mark on the body of the fuse. If the power cords plug is not suitable for your socket outlets, cut it off and fit a suitable plug. Fit a suitable fuse in the plug. For European Models Declaration of Conformity We declare, under our sole responsibility

19、5/255DAB Service Procedures - 3 ABOUT LEAD FREE SOLDER (PbF) Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PbF printing on the PCB. (Please refer to figures.) Caution: Pb free solder has a higher melting point than standard solder; Typically the melting point is 86oF

20、104oF(30oC40oC) higher. Please use a soldering iron with temperature control and adjust it to 650oF 20oF (350oC 10oC). In case of using high temperature soldering iron, please be careful not to heat too long. Pb free solder will tend to splash when heated too high (about 1100oF/ 600oC). All products

21、 with the printed circuit board with PbF printing must be serviced with lead free solder. When soldering or unsoldering, completely remove all of the solder from the pins or solder area, and be sure to heat the soldering points with the lead free solder until it melts sufficiently. Recommendations R
