  Note: 

y  The FWT can be powered by the power adapter or the spare battery. 
y  If the FWT is connected to the power adapter and the spare battery is inserted, 

the FWT is powered by the power adapter, and meanwhile, the spare battery is 
charged. 

y  Charge the spare battery for at least eight hours for the first time. If a 

fully-charged spare battery is left unused for a long time, charge it for at least 
five minutes before using it again. 

y  If the FWT is powered solely by the spare battery, the talk time is three hours to 

five hours or the standby time is 40 hours to 120 hours (the talk time and the 
standby time are network dependent). 

Press and hold 

  to power off your FWT. Connect the power adapter to the FWT, and 

plug it to the power socket. 

 

Press and hold 

 to power off your FWT and then disconnect the FWT from the 

power socket. Then install the spare battery as shown in the following figure. When 
installing the spare battery, make sure that the battery cord plug matches the battery jack. 
Do not insert conversely.
