(Europe, U.K.)

(PAL General)

The components designated by a symbol ( ! ) in this schematic diagram designates components whose value are of

special significance to product safety. Should any component designated by a symbol need to be replaced, use only the

part designated in the Parts List. Do not deviate from the resistance, wattage, and voltage ratings shown.

PRODUCT SAFETY NOTICE

RoHS

This product does not contain any hazardous substances prohibited by the RoHS Directive.

WARNING

You are requested to use RoHS compliant parts for maintenance or repair.

You are requested to use lead-free solder.

(This product has been manufactured using lead-free solder. Be sure to follow the warning given on page 2 when carrying

out repair work.)

WARNING

Do not use solder containing lead.

This product has been manufactured using lead-free

solder in order to help preserve the environment.

Because of this, be sure to use lead-free solder when

carrying out repair work, and never use solder

containing lead.

Lead-free solder has a melting point that is 30 - 40°C (86 -

104°F) higher than solder containing lead, and moreover it

does not contain lead which attaches easily to other metals.

As a result, it does not melt as easily as solder containing

lead, and soldering will be more difficult even if the

temperature of the soldering iron is increased.

The extra difficulty in soldering means that soldering time

will increase and damage to the components or the circuit

board may easily occur.

Because of this, you should use a soldering iron and

solder that satisfy the following conditions when carrying out

repair work.

Soldering iron

Use a soldering iron which is 70 W or equivalent, and

which lets you adjust the tip temperature up to 450°C

(842°F). It should also have as good temperature recovery

characteristics as possible.

Set the temperature to 350°C (662°F) or less for chip

components, to 380°C (716°F) for lead wires and similar,

and to 420°C (788°F) when installing and removing shield

plates.

The tip of the soldering iron should have a C-cut shape or

a driver shape so that it can contact the circuit board as flat

or in a line as much as possible.

Solder

Use solder with the metal content and composition ratio by

weight given in the table below. Do not use solders which

do not meet these conditions.

Lead-free solder is available for purchase as a service tool.

Use the following part number when ordering:

Part name: Lead-free solder with resin (0.5 mm dia., 500 g)

Part number: VJ8-0270

Metal content Tin (Sn) Silver (Ag) Copper (Cu)

Composition

ratio by weight 96.5% 3.0% 0.5%

Note:

If replacing existing solder containing lead with lead-free

solder in the soldered parts of products that have been

manufactured up until now, remove all of the existing solder

at those parts before applying the lead-free solder.
