Firmware and software upgrades

For the best interaction between your HDD and your
PC. Check www.philips.com/support for latest
upgrades available.

Firmware upgrade procedure

1. Download the latest version of the Device
Manager application from
http://www.philips.com/support. You may need to
enter your language preference and the model
number e.g.hdd084, to access the Device
Manager application upgrade file.

2. Double click the downloaded execution file to start
the installation of the Device Manager.

3. Once the installation is completed, connect the
GoGear to the power supply with the AC/DC
adapter.

4. Launch the Device Manager at Start->Programs-
>Philips GoGear HDD->Philips GoGear HDD on
your PC

5. A dialogue box will pop up; click Upgrade to start
the upgrading of the firmware. (Please do not

disconnect the jukebox during the upgrading
process as this interruption may damage the
firmware!)

6. Follow all screen instructions to complete the
firmware upgrade.

7. The Device Manager will close automatically once
the success message is displayed. Close all opened
application and then safely remove your GoGear

1.0 TECHNICAL SPECIFICATION and SERVICE HINTS

micro jukebox by clicking on the icon in your
task tray bar. When prompted, “The USB Mass
Storage Device can now be safely removed from
the system”, click OK and unplug your micro
jukebox.

8. Once the GoGear micro jukebox is disconnected
from the computer, the display will show
“Firmware Upgrading” for a couple of seconds
and then start up as usual. If the message does
not disappear after 2 minutes, do a soft reset by
pressing and holding the  key and the volume
+ key for a couple of seconds.

WARNING

GB

All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.

F

ATTENTION

Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler le bracelet serti d’une résistance de
sécurité.
Veiller à ce que les composants ainsi que les
outils que l’on utilise soient également à ce
potentiel.

2.0 SAFTETY INSTRUCTIONS

ESD

D

WARNUNG

Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.

WAARSCHUWING

NL

Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.

I

AVVERTIMENTO

Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevità potrebbe essere fortemente
ridatta in caso di non osservazione della più
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.

GB

Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.

NL

Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,
identiek aan de gespecificeerde, worden toegepast.

F

Les normes de sécurité exigent que l’appareil soit remis à l’état
d’origine et que soient utiliséés les piéces de rechange identiques
à celles spécifiées.

D

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu
beachten. Der Original zustand des Geräts darf nicht verändert werden;
für Reparaturen sind Original-Ersatzteile zu verwenden.

I

Le norme di sicurezza esigono che l’apparecchio venga rimesso
nelle condizioni originali e che siano utilizzati i pezzi di ricambio
identici a quelli specificati.

LASER PRODUCT

GB

Warning !

Invisible laser radiation when open.
Avoid direct exposure to beam.

S

Varning !

Osynlig laserstrålning när apparaten är öppnad och spärren
är urkopplad. Betrakta ej strålen.

Varoitus !

SF

Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiina
näkymättömälle laserisäteilylle. Älä katso säteeseen!

"After servicing and before returning set to customer perform a
leakage current measurement test from all exposed metal parts to
earth ground to assure no shock hazard exist. The leakage current
must not exceed 0.5mA."

DK Advarse !

Usynlig laserstråling ved åbning når sikkerhedsafbrydere er
ude af funktion. Undgå udsaettelse for stråling.
