643:  The call is disconnected when I pick up the handset of the Touch  8 on my EX90 and EX60. 

Why?

The light sensor in the early production handset cradles on the Touch 8 can be affected by 

some particular light conditions and this may cause false hang ups when the handset is picked 

up. Please contact your local support office if you experience this problem.

This issue can be prevented by changing the light environment of the Touch 8. Please notice 

that the EX90, EX60 and Touch 8 can be used without the handset. Alternatively, use the 

EX90 and EX60 in loud speaking mode or with a headset.
