1. ABOUT LEAD FREE SOLDER (PbF: Pb free)

Note:

Inthe information below, Pb, the symbol forleadinthe periodic table of elements, will referto

standardsolderorsolderthat contains lead.

We will use PbF solderwhendiscussing the leadfree solderusedinourmanufacturing process

whichis made fromTin(Sn), Silver(Ag), and Copper(Cu).

This model, and others like it, manufacturedusing leadfree solderwill have PbF stampedon

the PCB. Forservice and repairwork we suggest using the same type of solderalthough, with

some precautions, standardPbsoldercanalsobe used.

Caution

-PbF solder has amelting point that is50°F ~70°F (30°C~ 40°C)

higher than Pb solder. Please use asoldering iron with

temperature control and adjust itto 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 ifitisheated much higher than its

melting point, approximately1100°F (600°C).

-Ifyou must use Pb solder on aPCB manufactured using PbF

solder, remove as much of the original PbF solder as possibleand

be sure that anyremaining ismelted prior to applying the Pb

solder.

-When applying PbF solder to doublelayered boards, please check

the component side for excess which mayflow onto the opposite

side (See the figure below).

1.1. Suggested PbF Solder

There are several types of PbF solderavailable commercially. While this product is

manufacturedusing Tin, Silver, and Copper

(Sn+Ag+Cu), you canalsouse Tinand Copper(Sn+Cu) orTin, Zinc, and Bismuth(Sn+Zn+Bi).

Please check the manufac

turer’s specific instructions forthe melting points of theirproducts and anyprecautions for

using theirproduct withother

materials.

The following leadfree (PbF) solderwire sizes are recommendedforservice of this product:

0.3mm, 0.6mm and 1.0mm.

2. FOR SERVICE TECHNICIANS

ICs and LSIs are vulnerable tostatic electricity.

Whenrepairing, the following precautions will helpprevent recurring malfunctions.

1. Cover the plasticparts boxes with aluminum foil.

2. Ground the soldering irons.

3. Use aconductive mat on the worktable.

4. Donot touch ICor LSI pins with bare fingers.

3. CAUTION

Dangerof explosion if batteryis incorrectlyreplaced. Replace onlywiththe same orequivalent

type recommendencedbythe manufacturer.

Dispose of usedbatteries according tothe manufacture’s Instructions.

4. BATTERY

4.1. BatteryInstallation

Please ensure the batteries are insertedas shown. part shouldbe insertedfirst.

Close the coveras indicatedbythe arrow.

-When you replace the batteries, part shouldbe removed first.

4.2. BatteryCharge

At the time of shipment, the batteries are not charged. To charge, place the handset on the base

unit.

Please charge the batteries forabout 7 hours before initial use. During charging, the battery

icon is as shownbelow.

The handset whichpoweris off will be turnedon automaticallywhenit is placedon the base

unit.

Innormal use, the handset and the base unit shouldbe poweredon at all times.

Note forService:

The batterystrengthmaynot be indicatedcorrectlyif the batteryis disconnectedand connected

again, evenafterit is fullycharged.

Inthat case, byrecharging the batteryas mentionedabove, you will get a correct indication of

the batterystrength.

4.3. BatteryLife

-Batterylife isdependent on use and conditions but ingeneral

when using fullycharged Ni-MHbatteries (700 mAh):

Talktime: 10hrs approx.

Standbytime: 120hrs approx.

-When using Ni-Cdbatteries (250 mAh):

Talktime: 4hrs approx.

Standbytime: 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 theyare repeatedly

removed and replaced.

-Ifbatterylife isshortened then please check that batteryand

charge terminalsare clean.

-For maximum batterylife, itisrecommended that the handset is

not recharged until batteryicon flashes .

4.4. Replacing the Batteries

If the icon flashes aftera fewtelephone calls evenwhenthe handset batteries have

beenfullycharged, bothbatteries must be replaced.

Charge newbatteries forapproximately7 hours before initial use.

(The telephone line cordmust not be connectedtothe telephone socket at this time).

Whenreplacing the batteries, ensure that the correct batterytype is selected.

-To exitthe operation, press anytime.

-Donot use non-rechargeablebatteries. Ifnon-rechargeable

batteries are fitted and start charging, itmaycause the leakage of

the batteryelectrolyte.

Please use onlyPanasonic P03P(Ni-MH) orP03H(Ni-Cd) batteries.

There is no waytoreset base PIN whenthere is no handset registeredtothe base.

6.3.3.2. Thinkable Situation

-Customer mayask to reset base PINbecause theyforget it.

-Customer maybring onlyabase unitfor repairand there isno

handset registered to the base (Need to register another handset

to the base to confirm ifthe unitworks properlyafter repair).

-When original handset has broken and customer purchased anew

one, ifcustomer forget base PIN, customer cannot register the

new handset and mayask to reset the PIN.
