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.
