This switch also allows additionalchanges to be made while in the Invert or Charge Mode.When the inverter is first connected to the batteries, the inverter andremote go through an internal 10 seconds start-up test. After this testis completed, the ON/OFF switch can be pressed to turn on the inverter.Once the inverter has been turned on, momentarily pressing the ON/OFFswitch alternately turns the inverter On/Standby and Off.On models with the Search Mode function, the ON/OFF switch can be usedto enable or disable the Search Mode. While in the Invert Mode, pressingand holding this switch for three seconds causes the Search Mode toalternate between Disabled (inverter always on – indicated by the INVERTLED indicator always on) and 5W (inverter is looking for at least a 5 wattload to turn on and start inverting – indicated by the INVERT LED indicatorblinking once a second).On models with the battery charger feature, this switch can also beused to put the charger in standby (disables the charger) so that all theincoming power can be used exclusively for the AC loads. To put thecharger in standby, press and hold the ON/OFF switch for three seconds(you must be in the Charge Mode). When this happens, the chargingindicators (BULK, ABSORB and FLOAT) will go off. To activate the charger,press and hold the ON/OFF switch for three seconds again. When thecharger is again activated, one of the charging indicators will come on toshow the current charge stage.WARNING: When any external AC power is passingthrough the inverter and present on the output, pressingthe ON/OFF switch will not remove this AC power on theinverter’s output.Monitoring the LED IndicatorsMM-R and MM-RC RemotesThe three LED indicators on the left side of both the MM-R and MM-RCremotes (see Figure 13) will show you the operating status of the MMSeries inverter. Monitor the indicators to determine the mode of operation:INVERT (green) -• On (solid)- and the AC IN LED indicator is Off. The inverter is On. It is usingenergy from the battery to supply AC power to the loads connected tothe inverter.- and the AC IN LED indicator is On (solid). The inverter is in Standby.The external AC power (utility/shore power or generator) connectedto the inverter’s input is passing through the inverter to power the ACloads. The inverter will automatically turn on to power the AC loads ifthe external AC power is lost or disconnected.• Blinks On (once every second) - The inverter is in Search Mode. The ACload is below 5 watts (Search Watts default setting).
