Cameos utilize removable NiMH battery packs. If not connected to a
terminal with DTR present, the Cameo will automatically power off to
conserve battery life. The time-out value can be programmed from
the host terminal; the factory default time-out is two minutes.
Additional power features include:
• Low battery indicated by flashing LED and reported to terminal on demand
• Power On/Off controlled from terminal or keypad
