2. Listening and Paging in a Cross Lane system
With the AUDIO IN and AUDIO OUT wires disconnected, the T1 and T2 buttons control which menu sign
to talk or listen to. They also control which headsets to PAGE to. Disconnecting the AUDIO IN and
AUDIO OUT wires presents some issues if a cook or cashier needs to monitor both lanes:
•
If the cook or cashier is using a headset to monitor lane 1, and the order-taker is taking an order from
menu lane 2, or if the order-taker needs to PAGE the cashier, he/she must first press T1 momentarily,
then press PAGE to communicate privately with the cashier on lane 1. Then the order-taker can press T2
to resume taking the order on lane 2.
•
As an alternative, a monitor speaker from each base station may be installed in the kitchen. (Caution:
Monitor speakers are generally not recommended for duplex systems using C921AA base stations. The
speaker location and volume are usually too critical to avoid feedback. C921BA base stations can
usually be configured successfully to allow operation of monitor speakers.)
3. The vehicle alerts may echo in the headsets
With the Cross-Lane module turned ON, two rapid single tones may be heard from the lane 1 base station.
To eliminate this problem, turn down the volume of the ALERT TONE LEVEL control, on one of the base
stations.
