Voltage Metering
The Main Screen displays a DC Voltage Indicator in the form of a battery icon that indicates the
power source currently in use and its level. When the battery icon is filled green, the voltage of the
active power source (internal or external) is full. The background color will change from green, to
yellow, to orange, and to red as voltage depletes.

. No other backup power sources avail-
able. Automatic shutdown will occur soon.
The DC Voltage Indicator will only flash red when there are no other connected backup power
sources remaining with adequate voltage. When the DC Voltage Indicator is flashing red, automatic
shutdown will occur soon. During automatic shutdown, the 633 will display a warning, stop any
active recordings, finish writing files, and shut the 633 down. The PowerSafe Battery will power the
633 during this time.

Disconnected power source
Each power source and its voltage level is displayed on the Power Screen. Disconnected power
sources have a black background and no voltage level. The power source currently in use has a thick,
white border.
Voltage Range
The voltage range of the DC Voltage Indicator and the Warning Voltage Threshold can be ad-
justed for external DC power sources. These values are adjusted with the Setup Menu option
POWER > Ext DC Ref
. Adjust the DC Reference to match the type of battery being used to power the
633 externally. The voltage range and Warning Voltage Threshold for each setting are shown in the
following chart.
