  • Page 2 1. ABOUT LEAD FREE SOLDER (PbF: Pb free) Note: In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that contains lead. We will use PbF when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn), Silver (Ag), and Copper (Cu).
  • Page 3 1.1. Suggested PbF Solder There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper (Sn+Ag+Cu), you can also use Tin and Copper (Sn+Cu) or Tin, Zinc, and Bismuth (Sn+Zn+Bi). Please check the manufac turer’s specific instructions for the melting points of their products and any precautions for using their product with other materials.
  • Page 4 ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions. 1. Cover the plastic parts boxes with aluminum foil. 2. Ground the soldering irons. 3. Use a conductive mat on the worktable. 4.
  • Page 5 The handset which power is off will be turned on automatically when it is placed on the base unit. In normal use, the handset and the base unit should be powered on at all times. Note for Service: The battery strength may not be indicated correctly if the battery is disconnected and connected again, even after it is fully charged.
  • Page 6 - Do not use non-rechargeable batteries. If no-rechargeable batteries are fitted and start charging, it may cause the leakage of the battery electrolyte. Please use only Panasonic P03P(Ni-MH) or P03H(Ni-Cd) batteries. 5. LOCATION OF CONTROLS 5.1. Base Unit...
