want to try moving the switch through all of the
positions until your caller hears you clearly.
Experimenting with various switch settings will
not harm the amplifier or your telephone.
Change the Telephone/Amplifier Compatibility
Switch between position 5 and 6 to see if the
hum goes away in either position.Use the posi-
tion with no hum.

FCC REGISTRATION INFORMATION
This equipment complies with Part 68 of the FCC rules. On the bottom of the modular adapter
is a label that contains, among other information, the FCC registration number and ringer equivalence number
(REN) for this equipment. If requested, this information must be provided to the telephone company.
The telephone company may make changes in its facilities, equipment, operation or procedures that could affect
the operation of the equipment. If this happens, the telephone company should provide you advance notice in
order for you to make the necessary modifications to maintain uninterrupted services.
If you experience problems with your headset, please refer to the warranty section for information on warranty and
repair service. If the problem is causing harm to the telephone network, the telephone company may request that
you remove the equipment until the problem is resolved. In extreme cases, the telephone company may be forced to
disconnect your service before notifying you of the problem.
AN IMPORTANT WORD ABOUT LISTENING LEVELS
In addition to providing telephone access, your Headset Switcher Amplifier lets you use your Plantronics headset to
listen to music from your computer or other audio source. This extra versatility carries with it the need to consider
how you set your listening level.
Plantronics headsets have always been designed to safely limit short duration loud inputs like clicks, pops or tones
that infrequently occur during telephone conversations. The design of telephone systems helps to ensure that long
term listening presents a minimal risk of hearing harm.
This is not the case with external audio devices that can be turned up to very loud levels. Listening to music at high
levels for extended periods of time could be harmful to your hearing. Please take care to observe the following:
• Start with the volume control at a low setting
• Increase the volume control until you can hear the sound clearly and comfortably
• Do not increase the level beyond this point
We want you to get the best from your Switcher amplifier by listening to it at a safe level.

INFORMATIONS SUR L’HOMOLOGATION AUPRÈS DE LA FCC
Cet équipement est conforme à la Section 68 des Règlements de la FCC. Sur le dessous de l’adaptateur modulaire
se trouve une étiquette contenant, entre autres informations, le numéro d’homologation et le chiffre d’équivalence
de sonnerie (REN) pour cet équipement. Si la Compagnie des Téléphones demande ces informations, elles doivent
lui être fournies.
La Compagnie des Téléphones pourrait modifier ses installations, ses opérations ou ses procédures techniques qui
pourraient affecter le fonctionnement de l’équipement. Dans ce cas, la Compagnie des Téléphones est tenue de
vous fournir un préavis adéquat pour vous permettre d’apporter les modifications nécessaires pour maintenir un
service ininterrompu.
Si vous éprouvez des difficultés avec votre casque, prière de consulter la section concernant les garanties et le ser-
vice de réparation. Si ce problème endommageait le réseau téléphonique, la Compagnie des Téléphones peut vous
demander d’enlever cet équipement jusqu’à ce que la source du problème soit déterminée. Dans des cas extrêmes,
la Compagnie des Téléphones pourrait être forcée d’interrompre votre service avant de vous informer du problème.
NOTE IMPORTANTE CONCERNANT LES NIVEAUX D’ÉCOUTE
En plus de l’accès au téléphone, l’Amplificateur Headset Switcher vous permet d’utiliser votre casque Plantronics
pour écouter la musique en provenance de votre ordinateur ou d’une autre source audio. Cette versatilité supplé-
mentaire entraîne la considération du niveau d’écoute à établir.
Les casques Plantronics ont toujours été conçus pour limiter de façon sûre les bruits élevés de courte durée, tels que
les ‘clics’, ‘pops’ ou fréquences qui se produisent peu fréquemment lors d’une conversation téléphonique. La con-
ception des systèmes téléphoniques aide à assurer qu’une écoute prolongée présentera un risque minimal d’en-
dommagement de l’ouïe.
Ceci n’est pas le cas avec des appareils audio externes dont le volume peut être réglé extrêmement fort. L’écoute
de la musique à des niveaux très forts pendant longtemps pourrait endommager l’ouïe. Prière de respecter les con-
signes suivantes.
• Commencer par un niveau de volume bas.
• Augmenter le niveau de volume jusqu’à ce que vous puissiez entendre le son clairement et confortablement.
• Ne pas augmenter le niveau au delà de ce point.
Nous voulons que vous obteniez les meilleurs résultats avec votre amplificateur Switcher en l’écoutant à un niveau
sûr.
