CAUTION ..
Do not ship or store the CNVD-T with batteries
installed.
NOTE
The CNVD-T may be powered by as few as two
DL123A lithium batteries. If installing only two
batteries, they must occupy slots in the battery
compartment that are diagonally across from each
other. Operating the CNVD-T with less than four
batteries will result in significantly reduced battery
run time.
