(Note 1) Install commercially-available alkaline dry batteries into MDS-BTBOX-36. The batteries should be 

procured by customers.

(Note 2) These backup periods are estimated based on the JIS standard, assuming that the product is used 

at a room temperature. The actual backup period may vary depending on the batteries (type and 

storage period after production, etc.) and the operating environment. Thus, regard these values 

only as a guide.
