MDB1000
To make installation an easy one person job, the MDB1000 (Magnetic Decoder Box) is a light,
portable, battery operated device that provides signal performance indicators that assist in
locating and aligning the EUM3006. The MDB1000 picks up a magnetic signal from the
EUM3006 from any position within 4 inches of the EUM3006. This allows the installer to put
the MDB in a convenient position, regardless of the orientation of the EUM3006 or
awkwardness of the mounting location. By indicating 8 levels of signal strength and 5 levels of
signal quality, the MDB1000 allows the installer to find the optimal location and alignment. The
MDB1000 is shown in

2.1 Placing the MDB1000
The MDB1000 comes with a belt clip and two velcro straps, a short one to attach the
MDB1000 to your wrist or forearm and a longer one to attach to the EUM3006 itself or the pole
mount. So long as the MDB1000 is within 4 inches of the EUM3006, it picks up the magnetic
signal sent by the EUM3006. If MDB1000 does not indicate it is receiving a signal, move it
closer to the waist of the modem.
The EUM3006 will stop sending the magnetic signal one hour after it has been started. If in
doubt, simply re-power the EUM3006 to ensure that it is transmitting the MDB1000’s signal.
2.2 Powering the MDB1000
The MDB1000 requires two AA batteries. It is recommended that long-life batteries, such as
the Eveready Lithium LN91, be used, which have a long shelf life. Under normal conditions,
these batteries should last for many months. Unlike other batteries, lithium batteries are rated
to -40 C. However, sustained temperatures below -10 C will severely limit the battery lifetime.
