Why does the device operate slowly at 

times?

•  Reset device. Does problem remain? If this solves problem, 

check if user installed applications are causing system to 

slow down.

•  Check that enough free storage memory remains on device, 

so that device operates smoothly and efficiently.

•  If device shows low storage memory, delete unnecessary 

files, or transfer files to microSD card.

If you are unable to solve the problem, you should have the device serviced. Pack the device in the original 

box. (See “Unpacking the OT-200” on page 1.) Include a description of the problem and a checklist of the 

steps you took when trying to fix the problem. The information may be useful to the service personnel. Return 

the device to the place you purchased it.
