Wireless System BackBeat 903 & BackBeat 906 Date Codes
The date code of your product designates its date of manufacture, and it can be used to establish your warranty period. The date code is generally listed with your product’s model and part number, although this is not always the case.
The chart below can assist with understanding the date code
Example: If you see A9 on your wireless product. The A means month of August and the 9 is the year of 2009.
The two digit Date Code on this headband is located on the left side, which also has the on/off switch. Look at the inside surface (facing your ear) and you will see a printed “CE”. Above the CE are four lines of very small print. The Date Code is on the third line.
