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.

· When 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: 0.3 mm, 0.6 mm and 1.0 mm.

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.

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 BATTERY

4.1. Battery Installation

1. Insert the batteries negative (-) terminal first.

2. Close the battery cover.

Note:

· Use only rechargeable P03P (Ni-MH)/P03H (Ni-Cd) batteries.

4.2. Battery Charge

Place the handset on the base unit for about 7 hours before initial use.

When the batteries are fully charged,

Note:

· Clean the charge contacts of the handset and base unit with a soft, dry cloth, otherwise the batteries may not charge properly. Clean if the unit is exposed to grease, dust or high humidity.

· If the handset is turned off, it will be turned on automatically when it is placed on the base unit.

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.

· In that case, by recharging the battery as mentioned above, you will get a correct indication of the battery strength.

Important:

· Please use only the Panasonic batteries P03P(Ni-MH)/P03H(Ni-Cd).

· Use only rechargeable batteries. If you install non-rechargeable batteries and start charging, the batteries may leak

electrolyte.

· Do not mix old and new batteries.

· Use only 2 nickel metal hydride (Ni-MH) batteries or 2 nickel cadmium (Ni-Cd) batteries. Do not mix battery types.

· Ensure that the correct battery type is selected.
