Power Save Modes  
The MS2420 has five configurable power save modes.  Refer to the MetroSelect Configuration Guide for 
additional information on Power Save Modes.   
1.  Blink Power Save Mode: 
Blinks the laser OFF & ON after a configured period of non-use. 
When the scanner recognizes a bar code it will exit the Blink mode. 
 
2.  Laser Off Power Save Mode: 
Turns the laser OFF after a configured period of non-use.  The motor continues to spin allowing for a faster 
“wake” up time. 
Any movement detected by the IR will “wake” the scanner from the Laser Off power save mode  
(see Figure 26 on page 31).  
 
3. 
Laser & Motor Off Power Save Mode: 
Turns the laser and motor OFF after a configured period of non-use. 
Any movement detected by the IR will “wake” the scanner from the power save mode (see Figure 26 on 
page 31).  This mode’s “
wake” time is slightly longer due to the motor’s need to restart. 
 
4.  Dual Action Power Save Mode #1: 
Blinks the laser OFF & ON after a configured period of non-use; turns the laser and motor OFF at  
thirty-minute intervals. 
Example: 
If the power save timeout is set to 15 minutes. 
 
Any movement detected by the IR will “wake” the scanner from the power save mode (see Figure 26 on 
page 31).
