GETTING FAMILIARIZED WITH 1166/1166 AND 3666 
INSTALLING THE BATTERY TO 1166/1266 
When you first receive the package, the rechargeable battery is stored separately from 
the scanner. Unless you have 3666 for charging the battery directly, you will have to 
insert the battery into the scanner first.  
Note:  Any improper handling may reduce the battery life. 
1)  Hold the scanner still and insert the battery into the battery compartment at the 
bottom of the scanner. 
2)  Slide the battery latch to lock the battery in the compartment. 
3)  The scanner will respond with a long beep and its LED will come on and off shortly.  
Note: (1) To turn off the scanner, remove the battery. Refer to settings of “
Auto Power 
Off & Power-Saving”.   
 (2) For shipping and storage purposes, save the scanner and the battery 
separately. This will keep the battery in good condition for future use.   
 (3) When the battery charge becomes low, you will find the scanner cannot emit 
scan beam and its power-on beep sounds differently.
