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 solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn), Silver (Ag), and Copper (Cu).

This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used.

Caution

· PbF solder has a melting point that is 50°F ~ 70°F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron with

temperature control and adjust it to 700°F ± 20°F (370°C ± 10°C). In case of using high temperature soldering iron, please be careful not to heat too long.

· PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C).

· If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible

and be sure that any remaining is melted prior to applying the Pb solder.

· W hen applying PbF solder to double layered boards, please check the component side for excess which may flow onto the

opposite side (See the figure below).

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 manufacturer’s specific instructions for the melting points of their products and any precautions for using their product with other materials.

The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

2 FOR SERVICE TECHNICIANS

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 and ground them.

2. Ground the soldering irons.

3. Use a conductive mat on the worktable.

4. Do not touch IC or LSI pins with bare fingers.

3 CAUTION

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer.

Dispose of used batteries according to the manufacture’s Instructions.

4.1.3. Battery Life

After your Panasonic batteries are fully charged, you can expect the following performance:

Ni-MH batteries (700 mAh)

Operation Operating Time

While in use (talking) 16 hours max.

While not in use (standby) 170 hours max.

Note:

· Actual battery performance depends on a combination of how often the handset is in use (talking) and how often it is not

in use (standby).

· Battery operating time may be shortened over time depending on usage conditions and ambient temperature.

4.1.4. Battery Replacement

If flashes even after the handset batteries have been charged for 7 hours, the batteries must be replaced.

Important:

· W e recommend the use of Panasonic rechargeable Ni-MH batteries P03P (HHR-4EPT). If you install non-rechargeable

batteries and start charging, the batteries may leak electrolyte.

· Do not mix old and new batteries.
