Power Management System ... The "Power Manager"
• The MDM Tablet Cart features the new and improved "Power Manager", which is designed to continuously charge
even the most power hungry laptops using only one wall outlet.
• The system uses a "Round Robin" charging cycle that constantly evaluates the demand for power and allows
each electrical strip time to cool down. Cooler batteries last longer, and extended battery life saves you money.
• One Auxiliary Outlet is included on the side of the cart to plug in a video projector or printer. Since the "Power
Manager" dedicates power to the auxiliary outlet when in use, the risk of tripping the circuit is eliminated.
• A Divider Panel separates the computer/battery from the transformer, minimizing the transformer's heat impact on
the battery ... cooler batteries last longer.
The "Power Manager" has two LED indicator lights visible on the side of the cart that let you know what it is doing.
The light on the left is Amber and the right one is Red

Please Note: It is recommended
that nothing be plugged into the
Auxiliary outlet while charging

1. If the Amber light displays single blinks, it means the current required to power the auxiliary outlet is too high. Unplugging whatever is in
the auxiliary outlet should allow the "Power Manager" to resume charging the devices.
2. If both the Amber and Red lights start to blink, it means one set of devices is drawing too much current and the "Power Manager" needs to
be reset by turning it off and back on. If problem persists there may be a faulty device that needs to be removed.
3. If the Amber light displays double blinks, the internal temperature of the cart is too high. Open the doors of the cart and/or move the cart
to a cooler room. The cart should cool down without having to turn off the "Power Manager"

1. When the power button is switched to the "On" position, both
indicator lights will light up for approximately 2 seconds.
2. Both lights will then turn off while the "Power Manager" evaluates
the power required to charge the first set of devices.
3. The Amber light will come on and stay lit indicating that the "Power
Manager" is now in "Smart Charge" mode. This means that tablets
will be charged in groups, three minutes at a time.
4. Once the power needed to charge all of the devices in the cart
reaches a level that will not trip the circuit, the "Power Manager"
enters "All Charge" mode and both lights will be off. All devices are
now charging.
