Site Requirements
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).
