  Note: 

y  The FWT can be powered by the power adapter or the spare battery. 
y  If the FWT installed with the spare battery is powered by the power adapter, the 

spare battery is automatically charged. After the spare battery is fully charged, 
the charging stops. 

y  Before using the spare battery for the first time, charge the spare battery for at 

least eight hours. 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 3 hours to 5 

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 your FWT off. Then connect the corresponding end 

of the power adapter plug to the power supply jack and connect the other end of 
the power adapter to a power socket. 

 

Press and hold 

  to power your FWT off 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 reversely.
