INFORMATION ABOUT LEAD-FREE SOLDERING

Philips CE is producing lead-free sets from 1.1.2005 onwards.

IDENTIFICATION:

Regardless of special logo (not always indicated) one must treat all sets from 1 Jan 2005 onwards, according next rules:

Example S/N:

• Use only lead-free solder alloy Philips SAC305 with order code 0622 149 00106. If lead-free solder-paste is required, please contact the manufacturer of your solder-equipment. In general use of solder-paste within workshops should be avoided because paste is not easy to store and to handle.

• Use only adequate solder tools applicable for lead-free solder alloy. The solder tool must be able

• Adjust your solder tool so that a temperature around

• Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly to avoid mixed

• Use only original spare-parts listed in the Service-Manuals. Not listed standard-material (commodities) has to be purchased at

• Special information for BGA-ICs:

• For sets produced before 1.1.2005 (except products of 2004), containing leaded solder-alloy and components, all needed spare-parts

• On our website www.atyourservice.ce.Philips.com

o To reach at least a solder-temperature of 40 o To stabilize the adjusted temperature at the solder-tip o To exchange solder-tips for different applications.

solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400 otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed. To avoid wear-out of tips switch off un-used equipment, or reduce heat.

solder alloy types (leaded and lead-free). If one cannot avoid or does not know whether product is lead-free, clean carefully the solder-joint from old solder alloy and re-solder with new solder alloy (SAC305).

external companies.

- always use the 12nc-recognizable soldering temperature profile of the specific BGA (for de-soldering always use the lead-free temperature profile, in case of doubt)

- lead free BGA-ICs will be delivered in so-called 'dry-packaging' (sealed pack including a silica gel pack) to protect the IC against moisture. After opening, dependent of MSL-level seen on indicator-label in the bag, the BGA-IC possibly still has to be baked dry. (MSL=Moisture Sensitivity Level). This will be communicated via AYS-website. Do not re-use BGAs at all.

will be available till the end of the service-period. For repair of such sets nothing changes.

Bottom line of typeplate gives a 14-digit S/N. Digit 5&6 is the year, digit 7&8 is the week number, so in this case 2005 wk12

So from 0501 onwards = from 1 Jan 2005 onwards

Im portant note you avoid mixing solder-alloys ( leaded/ lead -free). So best to always use SAC3 05 and the higher temperatures belong to th is.

Due to lead-free technology some rules have to be respected by the workshop during a repair:

: In fact also product s of year 2004 must be treated in this way as long as

For additional questions please contact your local repair-helpdesk.

You will find this and more technical information within the "magazine", chapter "workshop news".

SERVICE INSTRUCTION

Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points:

· Route the wire trees correctly and fix them with the mounted cable clamps.

· Check the insulation of the AC Power lead for external damage.

· Check the strain relief of the AC Power cord for proper function.

· Check the electrical DC resistance between the AC Power Plug and the secondary side (only for sets which have a AC Power isolated power supply):

1. Unplug the AC Power cord and connect a wire between the two pins of the AC Power plug.

2. Set the AC Power switch to the "on" position (keep the AC Power cord unplugged!).

3. Measure the resistance value between the pins of the AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be larger than 4.5 Mohm (For U.S. it should be between

4.2 Mohm and 12 Mohm).

4. Switch "off" the set, and remove the wire between the two pins of the AC Power plug.

• Check the cabinet for defects, to avoid touching of any

inner parts by the customer.

CONNECTION AND CONTROLS

ons

Connecting other equipment to your

system

Use a cinch cable to connect AUX/CDR to the

analogue audio out terminals of an external

equipment (TV, VCR, Laser Disc player, DVD

player or CD Recorder).

Optional connection

The optional equipment and connecting cords

are not supplied. Refer to the operating

instructions of the connected equipment for

details.

Note:

– If you are connecting equipment with a mono

output (a single audio out terminal), connect it to

the AUX/CDR left terminal. Alternatively, you can

use a “single to double” cinch cable (the output

sound still remain mono).

Inserting batteries into the

remote control

Insert two batteries (Type R03 or AAA) into the

remote control with the correct polarity as

indicated by the "+" and "-" symbols inside

the battery compar tment.

CAUTION!

– Remove batteries if they are exhausted

or will not be used for a long time.

– Do not use old and new or different

types of batteries in combination.

– Batteries contain chemical substances, so

they should be disposed of properly.

For better FM stereo reception, connect an

outdoor FM antenna to the FM ANTENNA

MAINTENANCE AND TROUBLESHOOTING

If the signal is too weak, adjust the antenna or

connect an external antenna for better

reception.

Increase the distance between the Mini HiFi

System and your TV or VCR.

Clean deck parts, see “Maintenance”.

Use only NORMAL (IEC I) tape.

Apply a piece of adhesive tape over the missing

tab space.

Remove and reconnect the AC power plug and

switch on the system again.

Adjust the volume.

Disconnect the headphones.

Check that the speakers are connec ted

correctly.

Check if the stripped speaker wire is clamped.

Make sure the MP3-CD was recorded within

32-256 kbps bit rate with sampling frequencies

at 48 kHz, 44.1 kHz or 32 kHz.

¡ ™ 2

Check the speaker connections and location.

Select the source (CD or TUNER, for example)

before pressing the function button ( , , ).

Reduce the distance between the remote

control and the system.

Insert the batteries with their polarities

(+/– signs) aligned as indicated.

Replace the batteries.

Point the remote control directly towards the IR

sensor.

Set the clock correctly.

Press and hold TIMER ON/OFF to switch on the

timer.

If recording or tape dubbing is in progress, stop

recording.

Cleaning the Cabinet

Use a soft cloth slightly moistened with a mild

Cleaning Discs

Maintenance

When a disc becomes dirty,

clean it with a cleaning cloth.

Wipe the disc from the centre

motion.

Do not use solvents such as

benzene, thinner, commercially available cleaners,

or antistatic spray intended for analogue records.

Cleaning the disc lens

After prolonged use, dirt or dust may

accumulate at the disc lens. To ensure good

playback quality, clean the disc lens with Philips

CD Lens Cleaner or any commercially available

cleaner. Follow the instructions supplied with

cleaner.

WARNING

Under no circumstances should you try to repair the system yourself, as this will invalidate the

warranty. Do not open the system as there is a risk of electric shock.
