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 DK40i, 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).
