Installing/replacing the back-up battery

The battery (see Specifications, page 5) should be replaced every 5 years to ensure back
up during lengthy power outages. An on board capacitor provides 20 minutes of charge to
preserve the memory while the battery is being changed.
Note:
• Do not install the memory backup battery until the BW500 and BW500/L is
installed, as it begins operation immediately.
• The unit is supplied with one battery (battery P/N PBD-2020035 (BR 2335) or use
equivalent 3V Lithium battery). Insert the battery into the holder as shown in the
following diagram before using the BW500 and BW500/L.
Disconnect power before installing or replacing the battery.
