The cordless handset provides office mobility, allowing you to make and answer calls while away from your desk. Replacing the standard corded handset, the cordless handset contains a rechargeable battery that charges in the handset cradle when not in use.
To use the cordless handset (whether DECT or Bluetooth), you must pair the handset with the phone. For details, see Pairing the Cordless Module and Accessories on page .

The handset has two LEDs:

Blue – indicates the operational status of the handset
Green – indicates the status of the electrical charge of the battery

LED Color	LED State	Indicates
Blue	Solid	Handset is muted
	Blinking	Handset is in pairing mode
	Winking	Active audio path between Handset and Module
	Off	No audio path between Handset and Module OR Battery is dead
Green	Solid	Battery is fully charged
	Blinking	Battery is charging. Note: It is normal for the handset LED to cycle between blinking and solid as battery charge is maintained.
	Off	When handset is cradled and the LED does not flash or illuminate, this indicates an absence of battery power. During the first 30 – 60 minutes that the light is off, the battery may be trickle charging. If that is the case, the LED will resume normal behavior within that 60 minute period. If the LED remains off for more than 60 minutes, then either the battery is no longer chargeable or there is a problem in the charging circuit.

Blinking: LED is On and Off for equal amount of timeWinking: LED is On for a short period of time and Off for a longer period
