Low Battery Power During Operation
If during operation, the MR-HD100 senses that the battery
charge is low resulting in a low voltage condition, the unit alerts
the user with warning beeps -- less than 3% charge remaining --
and then powers down in an orderly manner, protecting the
stored video clips and metadata.
Power From External DC Battery Devices
The ability to charge the MR-HD100 battery when operating
using an external DC battery device is dependent on the load
placed on the MR-HD100.
Consider the following when using external DC battery devices
to power the MR-HD100. The typical external DC power source
for the video device is 12V or 14.4V.
Power Consumption Tables
Operation
When operating the MR-HD100 at 12V rather than 14.4V, the
power consumed remains the same, but the current draw
increases by a factor of 1.2 (14.4/12.0).
The Linksys dongle uses approximately 1.35W. This
represents about 30% of the power budget when not charging
the batteries.
