Connecting an SX5T Model With a BBU (Backup Battery Unit)
Your SX5T has either a Power Supply (part #74007301) or a Battery Backup Unit 
(BBU; part #74006803).
If your model has a BBU, it is shipped with the battery disconnected to prevent if from being
prematurely drained. 
The BBU must not be connected to a SX5T or to AC power when you
connect or replace the battery. Connecting the wrong wires to the battery terminals may 
cause severe damage to the device.

2.
Unlatch the battery compartment cover by using a coin to rotate its latch to the open position.

see Figure 6.
6.
Insert the battery into the battery compartment.
