Beta Program: Limited to first 100 invited customers, 1 per customer. 

Please send feedback or bug reports to support@mytaglist.com with the word "beta" in subject. 

IMPORTANT: YOU NEED A COMPATIBLE TAG MANAGER TO USE THIS PRODUCT.  

Fully compatible Tag Manager: Revision 5 or higher

Partially compatible Tag Manager: Revision 2~4

*How to check your Tag Manager revision:

From http://mytaglist.com/eth/  

Click "Settings" -> "Account" -> Click "+" to open the tag manager. 

Partially compatible Tag Manager may encounter problems with very narrow band (<50kHz) wireless settings. Also, "additional error checking" feature is not available. 

 If you don't have a Tag Manager with revision 2 or higher (those shipped before May 2013), you need to purchase a new Ethernet Tag Manager to use long range sensor tags. 

When this product is released at the end of the beta program, you can keep it or return it to get any bug fixes discovered during the beta period and a new battery with a payment of the price difference ($14) + shipping.
