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 manufac
turer’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.
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 recommendenced by the
manufacturer.
Dispose of used batteries according to the manufacture’s Instructions.

4 BATTERY
4.1. Battery Installation
Please ensure the batteries are inserted as shown. part should be inserted first.
Close the cover as indicated by the arrow.
• ••
• When you replace the batteries, part should be removed first.
4.2. Battery Charge
At the time of shipment, the batteries are not charged. To charge, place the cordless handset on the charger.
Please charge the batteries for about 7 hours before initial use. During charging, the charge LED will light as shown below.
The cordless handset, even when switched off, will be turned on automatically when it is placed on the charger.
The cordless handset will not operate while it is on the charger.
If the handset display flashes when the cordless handset is lifted off the charger, please charge the cordless handset
batteries at least 15 minutes.
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.
• ••
• Confirmation of Antenna Pict ( ) indication:
If Antenna Pict is indicated, charge time is about 7 hours.
However, if Antenna Pict is flashing, charge time becomes long.

• ••
• Times indicated are for peak performance.
• ••
• The battery operating time may be shortened depending on usage conditions and ambient temperature.
• ••
• Clean the charge contacts of the cordless handset and the charger with a soft, dry cloth. Clean if the unit is subject to
grease, dust or high humidity.
Otherwise the battery may not charge properly.
• ••
• The batteries cannot be overcharged unless they are repeatedly removed and replaced.
• ••
• For maximum battery life, it is recommended that the cordless handset not be recharged until the battery icon flashes .
4.4. Replacing the Batteries
If the icon flashes after a few telephone calls even when the cordless handset batteries have been fully charged, both
batteries must be replaced.
• ••
• Charge new batteries for approximately 7 hours before initial use.
• ••
• When replacing the batteries, be sure to set up the battery type even if you install the same type of batteries to
initialise battery remaining memory of your cordless handset.
• ••
• Do not use non-rechargeable batteries. If non-rechargeable batteries are installed and start charging, battery
electrolyte may leak from the unit.
• ••
• Open the battery cover by pressing down firmly on the notch and sliding it as indicated by the arrow below.
Replace both batteries and close the cover. Charge the cordless handset for about 7 hours.
Please order Panasonic HHR-4EPT (Ni-MH) or P-4NPT (Ni-Cd) batteries.
Note for Service:
• ••
• When Ni-Cd batteies are littled with the setting in ,icon might disappear and stop
charging even if the handset is on the cradle for avoiding overcharge.
