APPENDIX

This appendix describes locating and solving problems that you may encounter while using the OT-200.

Often after time spent troubleshooting, the problem is traced to something as simple as a loose connection. 

Check the following before proceeding to the problem-specific solutions. 

In each problem-specific section, try the steps in the order suggested. This may help you to solve the problem 

more quickly. Try to pinpoint the problem and thus avoid replacing non-defective parts. For example, if you 

replace batteries and the problem remains, put the original batteries back and go to the next step.
Keep a record of the steps you take when troubleshooting: The information may be useful when calling for 

technical support or for passing on to service personnel.

Refer to the following for general problems you may encounter. 

PROBLEM

SOLUTION

You cannot turn on the device

•  Plug AC adaptor directly into device to check device is 

functioning. If device functions properly, then issue may be 

with the battery.

•  Check that the battery is fully charged and properly installed 

into device.

You have trouble charging the battery

•  Check that the AC adaptor is plugged in correctly to the DC 

jack on the device, and the other end into the wall outlet.

•  If using the cradle for charging, check that the AC adaptor is 

plugged in correctly to the cradle and the wall outlet.

•  Check for damage to the power cables.
•  If battery has been used extensively and is old, replace with 

new battery and try again.

You have trouble connecting to the 

Internet

•  Check that device is connected to a WiFi network with the  

correct network key (password).

•  Check if the WiFi network provides an IP address 

automatically via DHCP. If not, contact your network 

administrator for the relevant IP address, subnet, gateway, 

and DNS servers, which you need to enter manually.

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.

It is recommended that you follow certain guidelines to prevent possible damage to the device and to keep it 

in a good condition.

•  Avoid using the device in dusty and extremely high or low temperature environments.
•  Do not spill water on the device or expose it to the rain.
•  Avoid removing the battery without turning off the device.
•  Do not apply strong force or shocks to the device.
•  Keep the device and its accessories away from children.
•  Do not insert metal objects into the charging/communications port of the device. This can short-circuit 

the battery and result in danger.

•  Use a soft, clean, and slightly moistened cloth to clean the device. Do not let water come into contact 

with the microphone, speaker, or with any of the connectors.

•  Do not wipe the device with any corrosive liquid or coarse objects. This can damage the outer surface 

of the device.

•  Do not leave the device in extremely high or low temperature environments.
•  If device is to be transported or stored for a long period of time, please remove the battery, and store 

both device and battery in a cool, dark, and dry place. Ideally, batteries should be stored at around 

25˚C, or within a temperature range of -10˚C ~ 30˚C to maximize longetivity. Batteries in storage 

need to be charged every 3 months to prevent battery degradation

•  Batteries in storage need to be charged every 3 months to prevent battery degradation.
