Noggin 9-Digital Video Logger (DVL)

9.2 DVL Temperatures
It is very important that the DVL only be operated when it can be kept warmer than -10 C
otherwise sensitive electronic components including the LCD screen may freeze. Never
start the DVL after it has been exposed to cold temperatures.
If the DVL will be operating in temperatures below -10 C, it should be kept in a wind-proof box
insulated with styrofoam or textiles and heated with hand-warmer packs, if necessary. If possible,
start the DVL in a warm temperature before placing it in the box. If the protective box is properly
insulated, the DVL can usually generate enough heat to keep itself warm.
