Cause/solution
Outside speaker and microphone may not be properly installed.
• Be sure speaker and microphone are isolated from each
other, and tightly mounted with enough foam packed around
each of them to absorb vibrations.
Outbound and/or inbound audio level may be set too high.
• Set outbound audio level just high enough to be heard by
customers. Lower inbound audio to comfortable level.
Note: Lower inbound audio setting may also prevent feedback
noise.
Echo canceller may be OFF or Effect level may be "LOW".
• Set echo canceller level properly.
Note: Default setting is "MAX"(LED:RED))
DNR may be OFF or Effect level may be "LOW".
• Set DNR level properly.
Note: Default setting is "MID"(LED:YELLOW))
The Center Module may fail to start up.
• Turn off the power and on the power again.
The Double-Drive-Thru function does not work properly. But, the
Single Lane operation works well.
• Check to see whether the power of the other Center Module is
set to ON.
• Check to see whether the Center Modules are correctly con-
nected.
• Check to see whether LANE A and LANE B are selected for
the lanes, respectively.
