3 Basic Operation
If you are not familiar with the basic operation of the
DLC COVERT II
, the following
instructions will help you get a quick overview. Before doing any operation, please
make sure you have correctly loaded the batteries into the
DLC COVERT II
and inserted an
SD card into the card slot. If the SD card is not installed correctly or it’s write-protect
is “locked”, the device will give an alarm with a long beep and then turns off
automatically. The following gives you detailed instructions of different operations.
3.1 Loading Batteries
The first thing to do with a
DLC COVERT II
is to load the batteries. In fact, there are
two methods to supply power for the device: one is to use eight AA batteries and the
other is to use an external DC power supply. It is recommended to use eight new
high-performance alkaline or lithium AA batteries. Internally the batteries are divided
into two paralleled groups; each group contains 4 batteries and can supply power for
the
DLC COVERT II
alone (with shorter battery life time). The device has eight battery
slots, as shown in Fig. 4. Slots 1, 2, 3 and 4 form one group, while slots 5, 6, 7 and 8
form the other group. .

NiMH rechargeable batteries can also be used, but they might have a shorter life span
due to their bigger capacity leakage with the time and low temperature. Hence, it is
recommended to use high performance alkaline or lithium AA batteries or lead-acid
secondary cell with 6V output.
