to check if the units
function correctly. If

NO
YES
The transmitter
code may need to
be re-downloaded
to the receiver
NO
!!Caution!!
Note: Before you proceed with the Download ID procedure located on Page 10 & 11, great
care and caution must be adhered to. Also, refer to Chart #4 for Tips and Considerations.
If by accident, the transmitters have been switched with another unit, by downloading the ID
code to a new receiver, it is possible for the transmitter to operate 2 units at the same time (if
the original receiver unit is still on the job site). Therefore it must be
certain that the transmitter / receiver pair are the correct set.
Secondly, once the download procedure is completed, ensure all other units on the job site are
stopped. Test the operation of the newly configured set to ensure no other
machines on the site work with the same transmitter.
Once you are certain that the transmitter / receiver pair are a unique set, continue
normal operations.
