Simple connectivity.

compliance.

The Jabra GN1220 is a cord offering inexpensive connectivity

to a wealth of telephone systems and no nonsense, hassle-free

compliance with the latest in EU noise regulations. The Jabra

GN1220 is part of the Jabra GN1200 Series and builds on the

same intuitive-to-use design.

- Makes our most popular corded headsets compliant with EU

Noise-at-work directive (EN 2003/10/EC)*

- Works with most desk phones including IP hard phones

- Microphone amplification when required

- Simple 8-position slide adjustment means no need for a user

manual (QD to RJ9 variant only)

Aside from complying with noise-at-work regulation the Jabra

GN1220 is the answer to a common issue. When hooking up

a new headset there is not always a dial tone. The problem

could be the headset or the telephone? But chances are it is the

cord. Even though the headset and telephone may be plug-com-

patible, the wiring is determined by the individual telephone

manufacturer.

Jabra GN1220 is available in two variants to fit almost any

need:

- QD to RJ9 with straight cord

- for connecting most telephones on the market to our most

popular headsets

- QD to QD with straight cord

- designed for GN Ellipse (when used with GN2000, GN2100

and GN2200)

The Jabra GN1220 (QD to RJ9) features eight separate wire con-

figurations - including three with built-in microphone amplifica-

tion. Simply connect the Jabra GN1220 and headset through the

QD (Quick Disconnect) plug and flick the slide from one position

to the next until a dial tone is heard. It’s as simple as that!

Noise-at-work compliance has never been more convenient.
