Short RF Range Issue on C1060 Wireless Base Stations
Potential serial numbers: 0922005319 through 0922006920
We have identified a potential RF range issue with base stations in the serial range mentioned above. The
distance from the base station to a headset before the signal breaks up or encounters static may be less
than normal. If you have any of these units in your inventory/stock, please return them to 3M for upgrade
or replacement. Please use the 3M CCD Repair Center Repair/Return Form and indicate “Short Range
per Tech Bulletin” as Problem/Symptom. If you encounter problems in the field with short RF range
symptoms, please contact Dave Heffelbower, 3M Technical Service @ 1-800-328-0033. Dave will work
with you in resolving the problem.
Outside Order Taking using 3M Cross-Lane Module
(78-6911-4396-6)
During periods when an order taker is standing outside for sunny day or speed team type of order taking,
the menu speaker, menu microphone and menu loop detector may be disabled. This allows vehicles to
pass by the menu post and vehicle detector loop without alerting the drive-thru intercom operators.
Disabling the menu post components can be accomplished by using the Cross-Lane Module as a switch to
cut off the order menu post components.
Mount the Cross-Lane Module to a wall near the base station. Connect the menu speaker, microphone
and loop detector through the Cross-Lane Module as shown in the figure on the following page. When
the Cross-Lane Switch is in the down position, the menu speaker, microphone and loop detector will be
disabled.
Note: This assumes that an external loop detector is used. If using a 3M internal loop detector, call 3M
Tech Service (800)328-0033 for additional instructions, or convert to an external detector.
