Low-power Detection
Battery-power indicator blinks in red color when the battery power is below 5%.
Blinking period varies in two steps:
- 1st Step 0.5 sec ON – 0.5 sec OFF
- 2nd Step 0.3 sec ON – 0.3 sec OFF
NOTE: Operational time after the low-power indication varies widely depending

operate for another 20 minutes approximately if any device (such as
wireless/cable communication, laser scanning, etc.) is not driven but only
keyboard/LCD are activated.
