Install One to Six Lithium-Ion Batteries - SM5

If you do not need the full runtime of eleven 18650 batteries, you can install between one and six. The included battery bracket is required to hold the batteries in place.

1. Disconnect any external power source from the SM5.
   You cannot use both internal batteries and external power simultaneously.
2. Ensure that your batteries meet the following criteria:
   • They are protected, button-top cells.
   • Their size specification is "18650."
   • They are all fully charged.
3. Insert up to six batteries into the battery tray.
   Note the directional battery icons embossed in the rear face of the battery tray. All batteries should be oriented positive-right.
   
   
   If using fewer than six batteries, fill slots starting from the bottom of the tray for better stability.
   
   
   
4. Remove the battery bracket from its compartment along the right side of the battery tray.
   
   
   
5. Insert the hooks on both ends of the battery bracket into the corresponding slots at the upper and lower edges of the battery tray.
   The rounded contours of the battery bracket should sit flush against the installed batteries.
   
   
6. Required: Set the SM5's voltage cutoff behavior.
   • Using the built-in display, go to Settings > Battery type > Lithium 18650.
   • Using the Configurator app, pair with the recorder and go to Configure > Battery Type > Lithium 18650.

   Choosing the correct Battery type allows the SM5 to maximize its runtime, and it allows the Song Meter Configurator mobile app to accurately estimate battery life percentage.

   If the Battery type setting is incorrect, the SM5 may shut itself down prematurely, and battery percentage readings will not be correct.
