Jabra GN1200
Simple connectivity. Greater convenience.
The Jabra GN1200 cord is the solution to a common problem of not being able to connect headset and telephone.
Even though most things have been standardized, the cord connecting the phone with the handset or headset is
anything but standard as each telephone manufacturer has its own wiring code. Now, with the universal “smart”
cord, Jabra GN1200, the cord will work with virtually any phone providing greater convenience.
•Works with most desk phones including IP hard phones
•Microphone amplication to boost transmit levels when connecting to low transmit volume phone systems
•Simple slide adjustment for easy setup
When hooking up a new headset there is not always a dial tone. The problem could be the headset or the tele-
phone? But chances are it is the cord. Even though the headset and telephone may be plug-compatible, the wiring
is determined by the individual telephone manufacturer.
Jabra GN1200 features eight separate wire schemes – including three with built-in microphone amplication. Just
connect the Jabra GN1200 and headset through the Quick Disconnect plug and ick the slider from one position to
the next until a dial tone is heard. It’s as simple as that!
Available in both straight and coiled versions, the Jabra GN1200 ts virtually all telephones featuring a standard RJ9
modular connector.
