CAUTION: Strobes require constant voltage and will not operate properly in the TEMPORAL MODE. A second Class “A”
output set in the NORMAL MODE will provide the constant voltage for the strobe circuit. Only use sounding appliances that can
use a coded signal. Do not use Wheelock AS/AH or NS/NS4/NH appliances with TEMPORAL MODE.
