Diagnostic Instructions
Thank you for purchasing the Welch Allyn
Halogen PocketScope Set. The operating and
maintenance instructions found in this manual
are for both the Ophthalmic and Diagnostic
model sets. They should be followed to ensure
many years of accurate and reliable service.
Please read these instructions thoroughly
before using your PocketScope.
Note:
While the handles and instrument heads of
the PocketScopes are interchangeable, different lamps are required for different instrument
heads. For the retinoscope use lamp No.
06200, for the ophthalmoscope No. 03900 and
for the otoscope/throat illuminator and transilluminator lamp No. 03400.
For guaranteed performance, use genuine
Welch Allyn lamps only.
Mode d'emploi des PocketScopes
™
Merci d'avoir acheté un jeu de PocketScope™
WelchAllyn.
A la différence des poignées et des têtes, qui sont interchangeables, les lampes à utiliser sont spécifiques à
chaque tête d'instrument. Veuillez consulter les diagrammes pour savoir comment remplacer les différentes
lampes.
Otoscope : (p. 7)
21131 – Tête d'otoscope standard (lampe 03400)
21111 – Otoscope avec source lumineuse pour la
gorge ( lampe 03400). Pour convertir l'otoscope en
source lumineuse pour la gorge, il suffit de dévisser
la tête de l'otoscope.
Rétinoscope : (p. 6)
Pour utiliser le rétinoscope, déployez l'appareil en tirant la
tête vers l'extérieur.
Le manchon de mise au point permet d'effectuer la mise
au point et la rotation des stries.
Ophtalmoscope : (p. 8)
Instructions relatives aux lentilles –
Dioptries ‘+’ - Faites pivoter le cadran de la lentille dans
le sens horaire. A+6, faites de nouveau tourner le cadran
de la lentille dans le sens horaire puis placez le ‘multiplier
lever’ sur la position ‘+’. Faites de nouveau pivoter le cadran de la lentille dans le sens horaire si vous souhaitez
atteindre les paramètres +7 à +22.
Dioptries ‘–’ - Faites pivoter le cadran de la lentille dans
le sens horaire inverse. A–9, faites de nouveau tourner
le cadran de la lentille dans le sens horaire inverse.
Placez ensuite le ‘multiplier lever’ sur la position ‘–’.
Continuez à faire pivoter le cadran de la lentille dans
le sens horaire inverse si vous souhaitez atteindre les
paramètres –10 à –25.

Bedienungsanleitung für
PocketScopes
™
Wir bedanken uns für Ihren Kauf eines PocketScope™Satzes von WelchAllyn.
Obwohl die Griffe und Instrumentenköpfe untereinander
austauschbar sind, werden für die verschiedenen
Instrumentenköpfe verschiedene Lampen benötigt.
Der Lampenaustausch ist auf den diagrammatischen
Abbildungen angezeigt.
Otoskop: (p. 7)
21131 – standardmäßiger Otoskopkopf (Lampe 03400)
21111 – Otoskop mit Halsbeleuchter (Lampe 03400). Zur
Konversion des Otoskops in einen Halsbeleuchter wird
einfach der Otoskopkopf aufgeschraubt.
Skiaskop: (p. 6)
Zur Verwendung des Skiaskops dieses zunächst
teleskopisch auseinander ziehen, indem der Kopf nach
außen gezogen wird.
Ein Brennpunktaufsatz ermöglicht die Scharfeinstellung
und Rotation des Streifens.
Ophthalmoskop: (p. 8)
Linsenanleitung –
‘+’ Dioptrie – Die Linsenscheibe im Uhrzeigersinn drehen.
Bei +6 die Linsenscheibe wiederum im Uhrzeigersinn
drehen und dann den ‘Multiplier Lever’ in die Position ‘+’
stellen. Die Linsenscheibe dann wieder im Uhrzeigersinn
für +7 bis +22 drehen.
‘-‘ Dioptrie – Die Linsenscheibe gegen den Uhrzeigersinn
drehen. Bei +9 die Linsenscheibe wiederum gegen den
Uhrzeigersinn drehen. Danach den ‘Multiplier Lever’ in die
Position ‘-‘ stellen. Die Linsenscheibe dann weiter für –10
bis –25 gegen den Uhrzeigersinn drehen.
Istruzioni d'uso del PocketScopes
™
Grazie per avere acquistato un set PocketScope™

03400). Per convertire l'otoscopio in illuminatore laringeo
basta svitare la testa dell'otoscopio.
Retinoscopio (p. 6)
Per usare il retinoscopio estrarre la testa dello strumento.
Un apposito cilindro di focalizzazione consente di ruotare
il fascio luminoso e di regolarne l’ampiezza.

Istruzioni per la regolazione della messa a fuoco.
Diottrie ‘+’ – Ruotare il selettore della lente in senso
orario. A+6 ruotare nuovamente il selettore in senso
orario, quindi portare la ‘multiplier lever’ sulla posizione
‘+’. Per le diottrie comprese tra +7 e +22, ruotare ancora
il selettore in senso orario.
Diottrie ‘-‘ Ruotare il selettore della lente in senso antiorario. A-9 ruotare nuovamente il selettore in senso antiorario, quindi portare la ‘multiplier lever’ sulla posizione ‘-‘ .
Per le diottrie comprese tra -10 e -25 continuare a ruotare
il selettore in senso antiorario.
