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 applyin g 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
turers 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 manufactures 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 handset on the base unit.
Please charge the batteries for about 7 hours before initial use. During charging, the battery icon is as shown below.
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.
In that case, by recharging the battery as mentioned above, you will get a correct indication of the battery strength.

4.3. Battery Life
· Battery life is dependent on use and conditions but in general when using fully charged Ni-MH batteries (700 mAh):
Talk time: 10hrs approx.
Standby time: 120hrs approx.
· When using Ni-Cd batteries (250 mAh):
Talk time: 4hrs approx.
Standby time: 40hrs approx.
(Times indicated are for peak performance)
· The batteries reach peak performance after several full charge/discharge cycles.
· The batteries cannot be overcharged unless they are repeatedly removed and replaced.
· If battery life is shortened then please check that battery and charge terminals are clean.
· For maximum battery life, it is recommended that the handset is not recharged until battery icon flashes .
4.4. Replacing the Batteries
If the icon flashes after a few telephone calls even when the handset batteries have been fully charged, 2 batteries must
be replaced.
Charge new batteries for approximately 7 hours before initial use.
(The telephone line cord must not be connected to the telephone socket at this time).
When replacing the batteries, ensure that the correct battery type is selected.
· To exit the operation, press any time.
· When Ni-Cd batteies are fitted with the setting in , icon will disappear and stop charging
even if the handset is on the cradle.
· Do not use non-rechargeable batteries. If non-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.

6.14. Automatic Route Selection
Automatic Route Selection is a feature which selects the least expensive carrier (network) service available, when making long
distance calls.
When area code(s) have been related to carrier codes, you will need only dial the area code, the lower costing carrier (network)
will automatically be dialled.
Please contact your telephone company regarding the carrier telephone charges.
6.14.1. Storing the Carrier Code(s)
Firstly you must subscribe to a second carrier (network) service. You can subscribe to a limit of 5 carrier services. Then store
the code as follows:
· To exit the operation, press any time.
· *1: The factory preset is 0000.
6.14.2. Storing the Area Code(s)
Store the area code(s) for which the chosen carrier (network) service charge rates are lower than the original carrier (network)
service. Up to 25 area codes can be stored.
· To exit the operation, press any time.
· *1: The factory preset is 0000.
· *2 If you need more area code storing, repeat the steps from 6.

6.14.3. Relate the Area Code(s) to the Carrier Code(s)
After storing carrier code(s) and area code(s), you must relate the stored area code(s) to your chosen lower costing carrier
code. It is only necessary to relate area codes to carrier codes if more than one carrier code has been stored. If only one carrier
code has been stored, any area codes you store (up to 25) will automatically be dialled with that carrier code.
