Your Dictograph burglar alarm system is precision-engineered and quality manufactured to meet the most stringent standards of excellence. A major feature of the system is its ability to switch over to "Emergency Power", assuring continued operation during a power failure, provided, of course, the "Emergency Power" is properly maintained according to Dictograph Security Systems instructions. Once the power is restored, the system will automatically transfer back to household electric. We recommend that the "Emergency Power Supply" be replaced with a fresh Dictograph battery every 12 months, regardless of its condition, to assure proper operation.
