Reducing Power consumption of DI-808

Reducing Power consumption of DI-808

Is there a way to reduce the power consumption of the DI-808 in stand alone mode?  I am planning a long term low sample rate (5 or 10 minutes) project at a remote location and want to power the DI808 with a battery.  Is it possible to disable the network interface to reduce power consumption or put the processor in a sleep mode between samples to reduce power consumption?
