The following combinations of corded and cordless headset and handset are supported on
the 5330e/5340e IP Phone:
  • Corded handset only
  • Corded handset and corded headset
  • Cordless handset only
  • Cordless handset and cordless headset

The DECT Cordless Handset, DECT Cordless Headset, and Bluetooth Handset are all Mitel-
branded accessories available only from Mitel. Bluetooth headsets are third-party
accessories available from a variety of manufacturers.

Before using a cordless handset or headset, it must establish communication with the
Cordless Module using a procedure called pairing.

Notes:
  • An IP phone can have only one DECT Cordless Handset and one DECT Cordless Headset.
  • A cordless handset or headset can be paired with only one IP phone at a time.
  • Pairing a new cordless handset or headset with the IP phone overwrites the configuration of any previous handset or headset
  • Pairing cannot be performed when the cordless device is already in use.

To pair a DECT cordless accessory:
  1. Ensure that the battery of the cordless device to be paired is at least partially charged.
  2. Press and hold the pairing button on the back of the Cordless Module (see page 72) for 5 seconds to activate phone pairing mode. The LED on the Cordless Module blinks. The Cordless Devices application opens on the phone and prompts you to place the accessory in pairing mode.
  3. Press and hold the hookswitch on the side of the cordless handset (see page 77) or headset (see page 80) for 5 seconds to activate accessory pairing mode. The LED on the cordless accessory blinks. After a moment, the Cordless Devices application displays protocol, firmware, hardware, and IPEI information for the device to be paired.
Note: If the LED on the Cordless accessory does not start to blink after 10 seconds,
the accessory requires charging or is still in factory battery saving mode
