5.0 Operation
CHANGE Button
This button scrolls through the selections available under each menu heading.
Each menu restarts if you missed the desired selections, so if a selection is
bypassed simply continue to press the MENU button until the desired selec-
tion reappears.
HOME Button
Hold down the HOME button for two seconds to return to the Home screens.
Info:
The MENU/HOME button can be used to reset the remote by
pressing and holding it down for 10 seconds. This is useful if the
display shows unrecognizable letters or symbols.
HOLD Button
Hold down this button for two seconds to stop the Home screens from scroll-
ing. Hold down again to restart the scrolling of the Home screens.
Info:
All adjustable inverter/charger settings in the ME-MR are saved
in non-volatile memory and are preserved until changed—even if
an inverter reset is performed (see Section 6.2), or if all power to
the remote or inverter is removed.
Info:
The ME-MR remote is only used to control an inverter. In
order to control or display a Magnum Energy accessory, you need
to use a ME-RC50 or ME-ARC50 remote control. Please refer to the
particular remote control owner’s manual on the Magnum Energy
website at www.magnumenergy.com for further information on
displaying accessories.

Operating the Inverter/Charger
Turning the inverter on
– Press the ON/OFF button to activate the inverter.
The inverter will either search for a load—using very little power from the bat-
teries—if in Search mode (see Figure 5-5), or will be actively inverting—using
power from the batteries to power the AC loads (see Figure 5-3). The green INV
LED is on when the inverter is actively inverting, and
fl
ashes when searching.
Turning the inverter off
– While the inverter is actively inverting or search-
ing, the ON/OFF button can be pressed to switch the inverter function off, and
this will turn the green INV LED off (see Figure 5-4).
Inverter Standby
– The inverter is in standby when it is active (green INV
LED is on) and the remote shows a charge status due to an external AC power
source (utility/shore or generator) passing through the inverter to power the
AC loads. During normal operation, the AC loads are powered by the external
AC power source. However, if a blackout or brownout condition occurs the
inverter senses these conditions, transfers to Inverter mode, and then powers
the AC loads connected to the inverter.
CAUTION:
If you have critical loads and are in Inverter Standby, do
not press the ON/OFF button to turn the inverter off. If the green INV
LED is off, inverter power will NOT be available to run your critical loads
should the external AC power be interrupted.
Equalize charging
– Equalizing is a controlled overcharge performed after
your
fl
ooded (or AGM1 type) batteries have been fully charged. It mixes the
battery electrolyte (to reverse strati
fi
cation) and removes sulfation that may
have built up on the plates. These conditions, if left unchecked, reduce the
overall capacity of the battery.
