Page 6: Important Service Safety Precaution
LC-22LE240 IMPORTANT SERVICE SAFETY PRECAUTION Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow: WARNING 1. For continued safety, no modification of any circuit should be attempted. 2.
Page 7 LC-22LE240 PRECAUTIONS FOR USING LEAD-FREE SOLDER 1 Using lead-free wire solder When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage or accident due to cracks. As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
