Phonecell ® SX5T CDMA2000 4 User Manual
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.
To connect an SX5T model with a BBU:
1. Make sure the BBU is disconnected from the SX5T and the AC power cord.
2. Unlatch the battery compartment cover by using a coin to rotate its latch to the open position.
3. Remove the cover.
4. Connect the black wire ( - ) in the battery compartment to the black terminal (-) on the battery -
see Figure 6.
5. Connect the red wire ( + ) in the battery compartment to the red terminal ( + ) on the battery -
see Figure 6.
6. Insert the battery into the battery compartment.
7. Reattach the compartment cover and secure it with the cover latch.
8. Insert the barrel connector of the Power Supply and Battery Backup Unit’s cord into the SX5T’s
Power Input - see Figure 3 on page 2.
9. Connect the AC power cord to the Power Supply and Battery Backup Unit, then plug it into a
power outlet - see Figure 3 on page 2.
10. Press the Battery Power Switch on the BBU to the ON ( | / right) position.
11. Slide the Power Switch on the SX5T to the ON (right) position.
12. Check the cellular signal strength and move the unit until you achieve the best signal
possible - see LED Status Indicators on page 8 for more information.
