Chapter I (Power, batteries and charging…) July 20107Time Code and Real Time Clock (RTC) powering.A “super capacitor” will keep the time code and real time clock running for about 3 minutes if the battery boxis removed from the machine and no external DC is present on the 4 pole XLR connector. This ensures thatthe time code will remain accurate while the battery pack is replaced. If the date and time is lost, then it willautomatically be requested when the next power on is made.External DC poweringThe Nagra VI may be powered through the 4-pole XLR connector on the left side of the chassis with a DCsupply ranging from 9 to 16V and is designed to power the recorder from car batteries and so on. As soonas an external DC supply is connected the recorder will switch seamlessly to this supply and the batterypack on the rear will no longer be consumed. It may even be removed entirely from the recorder ifnecessary.With external DC power present on the 4 pole DC connector, the battery indicator on the main display willshow the yellow “flash” across it to indicate that sufficient external DC is available and the red “Low battery”portion is eliminated. This means that with 16V supplied the battery symbol will be “full” and with only 9Vapplied the indicator would be at the left end.- No external DC present with a full battery pack attached- External DC connected with about 13V appliedNote: The external DC supply can be connected and disconnected at any time without any interference tothe machine even during recording as long as a charged battery pack is fitted to the rear of therecorder.
