Tips for Troubleshooting 
In each problem-specific section, tr y the steps in the order suggested. This may help you to solve the 
problem more quickly. 
Try to pin point 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 troubles hooting: The information may be useful when call-
ing for technical support or for passing on to service personnel.

HDMITM Q & A 
Q. What is the difference between a “Standard” HDMITM cable and a “High-Speed” 
HDMITM cable? 
Recently, HDMITM Licensing, LLC announced that cables would be tested as Standard or 
High-Speed cables.  
․ Standard (or “category 1”) HDMI
TM cables have been tested to perform at speeds of 75Mhz 
or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.  
․ High Speed (or “category 2”) HDMI
TM cables have been tested to perform at speeds of 
340Mhz or up to 10.2Gbps, which is the highe st bandwidth currently available over an 
HDMI
TM cable and can successfully handle 1080p signals including those at increased color 
depths and/or increased refresh rates from the Source. High-Speed cables are also able to 
accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 
2560 x 1600). 
 
Q. How do I run HDMITM cables longer than 10 meters? 
There are many HDMITM Adopters working on HDMITM solutions that extend a cable’s effective 
distance from the typical 10 meter range to much longer lengths. These companies 
manufacture a variety of solutions that includ e active cables (active electronics built into 
cables that boost and extend the cable’s signal), repeaters, amplifiers as well as CAT5/6 and 
fiber solutions. 
 
Q. How can I tell if a cable is an HDMITM certified cable? 
All HDMITM products are required to be certified  by the manufacturer as part of the HDMITM 
Compliance Test Specification. However, ther e may be instances where cables bearing the 
HDMI
TM logo are available but hav e not been properly tested. HDMITM Licensing, LLC actively 
investigates these instances to ensure that the HDMITM trademark is properly used in the 
market. We recommend that consumers buy  their cables from a reputable source and a 
company that is trusted.
