Troubleshooting and Maintaining an SDS 
 
Quatech SDS User’s Manual 
Maintaining an SDS 
Operating conditions 
The SDS series is designed to work in environments that are free 
from dust, dirt, and moisture. You can operate an SDS at 
temperatures between 0° to 70°C. Do not leave an SDS where 
moisture can condense on it. 
Handling the SDS 
The following information can help you to use the SDS in a reliable, 
trouble-free manner. 
¾ 
Make sure the SDS is off before you connect or remove the 
Ethernet cable. 
¾ 
Make sure that all serial devices are connected correctly. 
¾ 
Protect the SDS from excessively dirty or damp conditions. 
¾ 
Do not drop, strike, or handle the SDS roughly. Handle it like any 
other piece of sensitive electronic equipment. 
Moving the SDS 
Follow these steps if you need to move your SDS or prepare it for 
shipment.  
¾ 
Disconnect the power cable. 
¾ 
Disconnect all other cables. 
¾ 
If you are shipping the SDS, use the original packing material 
and container. If you no longer have the original packaging, use a 
sturdy carton and sufficient packing material to protect the SDS 
during shipment. 
Cleaning the SDS 
Clean the outside of the SDS as needed with a slightly moist soft 
cloth. Do not use solvents or abrasive cleaners.   
Servicing the SDS 
There are no user-serviceable parts in the SDS. Contact Quatech for 
repair. Be sure to obtain an RMA number from Quatech technical 
support before returning your SDS for service.
