Programming the Headsets for Cross-Lane Operation
Follow the steps below to program the C960 headsets for Cross-Lane operation, and disable the Talk-Lock
function. It does not matter which base station is used to program the headsets. By pressing T1, the headset will
always communicate with the lane 1 base station; by pressing T2, the headset will always communicate with the
lane 2 base station.
1. Disable the Talk Lock function
Talk-Lock is a toggle function that must be checked first to see if it is enabled or disabled. If the Talk LED
lights when the L button is pressed, Talk-Lock is enabled.
•
To disable Talk-Lock, turn the headset OFF, press and hold the L button while pressing ON for 5
seconds. You will hear an acknowledging beep.
•
Recheck the Talk-Lock function by pressing the L button. The Talk LED on the base station should not
light.
