Changing the Batteries

 

 
 

NOTE :

 For optimum performance, the batteries should always be replaced with three good 

quality AA alkaline 1.5V batteries !! 
 
Simply lift the clip at the bottom of the front face, and lift the front cover upwards. 
 
Insert  the  new  batteries  taking  care  of  the  battery  orientation  –  which  is  stamped  on  the 
bottom of the battery enclosure. 
 

Please Note:

 Installing the batteries backwards will not damage the 

MagnaRod
