Talk Lock Explanation
TALK LOCK mode was designed to allow order takers to communicate hands free without
pressing any buttons. In TALK LOCK mode, the C960/C860 automatically switches from STANDBY to
TALK/LISTEN when a vehicle is detected at the menu sign and then back to standby when the vehicle
leaves the menu sign. When the next vehicle arrives, a single alert tone (or one double tone if set to
LANE 2) will be heard and the system will automatically start talk/listen operation.
TALK LOCK is only available if it has not been disabled, if the system is operating in duplex, and if the
system has a "presence detecting" type of vehicle detector.
To use the TALK LOCK mode, press the TALK LOCK switch. To return to normal operation, press
either TALK switch or the PAGE switch. For those customers who DO NOT wish their employees to use
TALK LOCK, the function can by disabled by a special programming step. (All units are shipped with
TALK LOCK enabled.)
