Black Cat II Radar Recorder User’s Manual
1-4
A fully charged battery should register at 13.4 or higher. If your battery
is lower than this, we recommend that you charge it before the first use.
Note that the Black Cat II will not turn on if the battery voltage is below
12.0. Also note that the Black Cat II will stop collecting data once the
battery falls to 11.2 volts.
We recommend that you disconnect the battery whenever the Black Cat II
Radar Recorder is not in the field collecting data.
Keeping your battery properly charged is very important. The rechargeable
battery will begin to decay and become less effective if it is allowed to fall
below 11.0 volts. To avoid having to replace your battery prematurely,
keep it consistently charged. A well-maintained battery will last for years
without having to be replaced. Refer to Chapter 5 Battery Care for more
information on battery maintenance.
Before You Begin
Before you attempt to collect important data with the Black Cat II Radar
Recorder we strongly recommend that you familiarize yourself with both the
operation of the Black Cat II Radar Recorder, and the software that is used
with it, by reading all of the documentation that came with the equipment.
Whenever possible, we recommend that you perform a test study if you
are new to the Black Cat II Radar Recorder. This will help you become
comfortable with the operation of the equipment and how the data is both
collected and analyzed. This should make things easier for you when you
have to do your first real study.
