Wireless System BackBeat 903+ Date Code
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 I0 on your wireless product, I is the Month of September and the 0 is the year of 2000.

The two character Date Code is located on the left side, which is on the same side as the power button. Look at the inside surface (the side facing your ear). You will see “CE” printed in a large font. To the right of the CE you will four characters: two letters printed above one letter and one number (for example, “BC” on the top line and “A1” on the bottom line). The Date Code is the letter and number located on that bottom line. Note: In the image below, the Date Code would be the letter “I” and the number zero.
