The SuperNova Battery Power Supply...
The SuperNova and SuperNova 2 can be powered two ways: by wall power, or by battery power supplied by the four packs of seven batteries in the SuperNova Battery Power Supply. The remote power supply supports NiMH recharchable batteries but is designed to work perfectly without the batteries as well. The batteries will allow the SuperNova or Supernova 2 to run completelty isolated from wall power for up to three hours. At this point the SNPS will go back into charging mode (flashing). It is recommended that the SNPS be returned to this state (charging mode) after each use. We recommend that you do not unplug the SNPS from the wall.If there is a power disruption, disconnect the SNPS ribbon cable from the SuperNova or SuperNova 2.

Problem: Unit goes into charging mode repeatedly.
The battery charging system may need several charging cycles before the Nova Phonomena is fully charged. Because the maximum charging time is limited by software and the batteries are so high capacity, the battery packs are actually not fully charged for several cycles. The unit will still operate perfectly, but the indicator light will not indicate a full charge for several cycles.
Problem: Batteries have come loose in shipping.
There have been instances of the battery packs coming loose during shipping. We have addressed this by adding a third battery strap to the units. If your batteries have come loose, reconnect them as per the diagrams on the Battery Replacement page.
Problem: After several years of use, batteries fail to hold a charge.
Batteries will eventually need to be replaced (they average about a four-year life span). See the Battery Replacement page for further details.
Problem: System noise or hum.
With the Nova Phonomena set at very high volumes and no record playing, there exists the possibility of a very slight hum coming from the unit. This is normal, and will not be evident under normal circumstances with a record playing at reasonable volume. It is not unusual to have a little noise in an analog-based system, especially at very loud playback levels. Most prefer this to the sterility of digital.
Do not leave the SuperNova Power Supply (SNPS) connected to the SuperNova while not plugged into the wall. This will quickly compromise the integrity of the batteries. We suggest leaving the SNPS plugged in to wall power at all times.
