Power for the display is provided in two ways: via standard 120 VAC line, or by means of
two sealed lead-acid DC batteries. Daktronics supplies two 12 V batteries, rated at 28
ampere hours (A/H), as original equipment. Refer to Section 5: Battery Care & Charging
(p. 9) for information on battery care and use of the on-board battery charger.
The provided 8' (2.4 m) 120 VAC power cord plugs directly into the three-prong POWER
IN 120V AC receptacle, located on the back panel of the display ( Figure 5 ). Any time
120 VAC power is connected, the internal charger operates; however, the system will not
overcharge the batteries. When the power cord is not connected, the display runs on
battery power.
The MS-2113 is shipped ready for use. The battery charger is factory-mounted in the
display, and all internal wiring is in place and connected to the driver and batteries.
The
ON/OFF control switch ( Figure 5 ) activates power to the internal display components,
as well as to the radio receiver or control console.
• Flip the switch to
ON for display operation.
• At all other times, keep the switch in the OFF position.
