The location must not be:
◆ Subject to extreme heat or cold
◆ Subject to corrosive fumes, dust, or other airborne contaminants
◆ Subject to excessive vibration
◆ Next to television, radio, office automation, or high frequency equipment
If reserve power is to be installed for the Strata DK40, the batteries will require a well-
ventilated location close (within nine feet) to the DKSUB40 (the optional Toshiba-supplied
battery cable is nine feet in length).
