The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this
equipment in considering the globally environmental conservation. 

The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin
(Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30 degrees C (86

°F) more than that

of the normal solder.

• The lead free solder has to be used when repairing the equipment for which the lead free solder is used.

(Definition: The letter of "PbF" is printed on the PCB using the lead free solder.)

• To put lead free solder, it should be well molten and mixed with the original lead free solder.
• Remove the remaining lead free solder on the PCB cleanly for soldering of the new IC.
• Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the

lead free solder.

• Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30 degrees

C (662±86

°F).

• The following 3 types of lead free solder are available through the service parts route.

RFKZ03D01KS-----------(0.3mm 100g Reel)
RFKZ06D01KS-----------(0.6mm 100g Reel)
RFKZ10D01KS-----------(1.0mm 100g Reel)

* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%

The letter of "PbF" is printed either foil side or components side on the PCB using the lead free solder.

recorded tapes or discs or other published or broadcast
material may infringe copyright laws.

To reduce the risk of fire or shock hazard, do not expose
this equipment to rain or moisture.

To reduce the risk of fire or shock hazard and annoying
interference, use the recommended accessories only.

 DO NOT REMOVE THE OUTER COVER
To prevent electric shock, do not remove the cover. No user
serviceable parts inside. Refer servicing to qualified service
personnel.

For your safety, please read the following text carefully.

This appliance is supplied with a moulded three-pin mains plug
for your safety and convenience.
A 5-ampere fuse is fitted in this plug.
Should the fuse need to be replaced please ensure that the
replacement fuse has a rating of 5 amperes and it is approved
by ASTA or BSI to BS1362
Check for the ASRA mark or the BSI mark on the body of the
fuse.

If the plug contains a removable fuse cover you must ensure
that it is refitted when the fuse is replaced.
If you lose the fuse cover, the plug must not be used until a
replacement cover is obtained.
A replacement fuse cover can be purchased from your local
Panasonic Dealer.

If the fitted moulded plug is unsuitable for the socket outlet in
your home then the fuse should be removed and the plug cut
off and disposed of safety.
There is a danger of severe electrical shock if the cut off plug is
inserted into any 13-ampere socket.

If a new plug is to be fitted please observe the wiring code as
shown below.
If in any doubt, please consult a qualified electrician.

The wires in this mains lead are coloured in accordance with
the following code:

     

As the colours of the wires in the mains lead of this appliance
may not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:

The wire which is coloured BLUE must be connected to the ter-
minal in the plug which is marked with the letter N or coloured
BLACK.

The wire which is coloured BROWN must be connected to the
terminal in the plug which is marked with the letter L or coloured
RED.

Under no circumstances should either of these wires be con-
nected to the earth terminal of the three pin plug, marked with
the letter E or the Earth Symbol.

remove the Connector Cover as follows.

1. Remove the Fuse Cover with a screwdriver.

2. Replace the fuse and attach the Fuse cover.

1. Remove the Monitor P.C.B. (Refer to Disassembly Procedures.)
2. Unsolder the Lithium Battery "ML-614S/DN" and then replace the new one. (See Fig. B1)

Fig. B1

The lithium battery is a critical component. 
(Type No.: ML-614S/DN Manufactured by Energy Company, Panasonic Corporation)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.

Above caution is applicable for a battery pack which is for SDR-H100/H101 series, as well.
