2: MDB1000
It is recommended that the batteries be tested before starting the installation. Keeping a spare
set of batteries with the installation tools may save you a trip down ladders, etc. to get new
batteries.
The AA batteries fit into the MDB1000 by removing the battery cover at the back of MDB1000,
removing the old batteries, and inserting the new ones. Ensure batteries are inserted with the
correct polarity.

2.3 Turning the MDB1000 On
The MDB1000 is self-tested every time it is turned on. Press the ON button. Each LED should
flash on and off twice a second for 5 seconds before showing the signal performance values. If
this does not happen, then the batteries could be low and should be replaced.
The ON/BATT LED will flash continually when the battery is low and should be replaced.
