3.5 EP10 Indicators
The EP10 uses LEDs (Light Emitting Diodes), onscreen messages and audio tones to indicate the various
conditions of the EP10, the batteries, the scans and so on.
3.5.1 LEDs
Three LEDs are located on the upper-right side of the EP10, just above the display. When you press the
[Power] button, the LED flashes yellow to indicate that the EP10 has been powered up. The LED table fol-
lowing outlines the behaviour of the LED while the EP10 is docked in a charger.
Keep in mind that the application running on the EP10 can dictate how the application LED operates.
Review the documentation provided with your application to determine LED behaviour.
If the EP10 is attached to an external power supply, the charge LED (the left-most LED) reflects the battery
charge status.
