C960 Tips and Tricks
1. C960 Cross Lane Operation
When installing two C960 Base Stations and a Cross Lane Module, where one headset may
communicate with both base stations, please note the four basic facts below:
1. You must configure the headsets for CROSS LANE operation.
a.
With the headset OFF, press and hold T1 and T2 while pressing ON for 5 seconds. You
will hear an acknowledging beep.
b.
To remove this function and lock T1 and T2 back together, first turn the headset OFF, then
hold down either T1 or T2 while pressing ON for 5 seconds. You will hear an
acknowledging beep. (Holding down T1 configures the headset to be a LANE 1 headset;
holding down T2 configures it for LANE 2.)
2. Both vehicle alert tones may be heard at all times.
The operator may object to hearing the vehicle alert from the other lane while taking an
order; if so, we suggest you turn the ALERT TONE LEVEL down on each base station so it is
audible in the headsets but not objectionable. The tone should be low enough so that the operator
can ignore it, yet know that someone is waiting at the other lane.
3. Both menu mics may be heard at the same time.
If the operator is talking to lane 1 and the lane 2 alert tone sounds, the operator should
ignore the tones and finish the transaction on lane 1. If the operator presses T2 to cancel the tone,
the operator will hear both menu mics at the same time until one car drives off the loop. This
is
not
a recommended mode of operation.
If this is a problem, the AUDIO IN and AUDIO OUT wires may be disconnected from the
Cross-Lane Module. Then the operator will only hear the menu mic from the lane with which
he/she last talked. (Caution: With the Audio In and Out wires disconnected, anyone monitoring
both lanes will only hear the lane with which his/her headset last talked.)
