Hardware Overview
Events Affecting Battery Life
Event (Cause)
In order to make a change to a
channel attribute, the channel
must first be disabled (OOS), and
then enabled (AUTO) again after
the change. The act of changing
the mode between OOS and
AUTO makes the WDM poll for all
of the static attributes of the
device.
Storing the SKF Multilog WVT
Because the unit does not turn off, if you remove a battery powered SKF Multilog WVT
from the network for storage, it will continue to search for the network. To conserve
battery power and preserve the battery level, be sure to flip the power switch PWR to
the EXT position. Do not remove the batteries from the unit because that will reset the
battery level.
