The backlight comes on when any key is pressed or when there is an 
incoming call and stays on for ten seconds. It turns off after ten

The Wireless Telephone Headset 
 
SpectraLink offers optional headsets for use in noisy environments 
or if you need to have your hands free while talking on the Wireless 
Telephone. 
To use the headset, simply plug it into the jack on the side of the 
Wireless Telephone. The headset is specially designed to work 
properly with The Link Wireless Telephone. We do not recommend 
using other headsets.
