Power
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:
• Full charge will print approximately 3000” (76 m) of receipt stock.
• Low battery indicated by flashing LED and reported to terminal on demand
• Power On/Off controlled from terminal or keypad
