The Jabra GN1200 Universal Smart Coiled Cord is a universal “Smart” Adapter Cable designed to connect Jabra corded headsets to a wide variety of desk phones.
Key Features
- Universal Compatibility: It features an 8-position slide adjustment switch that allows users to manually reconfigure the internal wiring. This ensures compatibility with roughly 90% of all desk phones, including brands like Cisco, Avaya, Panasonic, and Nortel.
- Built-in Microphone Amplifier: Three of the eight switch settings include integrated microphone amplification to boost transmit levels for phone systems with low transmit volume.
- Connectors: One end has a Quick Disconnect (QD) plug for Jabra headsets, and the other has a standard RJ9/RJ10 modular plug for desk phone headset ports.
- Design: It is a coiled (curly) cord with a length typically ranging from 0.6m to 2m when extended.
Usage Instructions
- Connect the Quick Disconnect end to your Jabra headset.
- Plug the RJ9 end into the headset port of your desk phone.
