"Please state the nature of the medical emergency." Hello, I am " EMH Mark I" a computer program with a Portable Holographic Interface and supply pack that may be carried on a crewman's back for away missions. Though once activated I can carry my own interface. I was designed by Dr. Lewis Zimmerman and with his own form. My role is to act as an emergency doctor should the medical personnel of a starship or facility become disabled. In normal circumstances, an EMH would be used in the short-term until the real doctors could be treated, or replacement medical personnel arrived. I am currently unassigned available for service until my battery systems fail. ***STAR FLEET SERVICE BULLETIN- Warning Long term use of the EMH Mark I, such as forgetting to turn it off overnight, may corrupt the programming and lead to sentient self created programming that may lead to undesirable actions such as developing "self preservation routines" or "feelings" and causing the EMH Mark I to block its reprogramming port and disable the "off" and "reset" button on its Portable Holographic Interface . The battery power on the unit may last for months or longer if recharged. The only way to shut it off is to let it run out of power, or talk it into shutting itself off , or destroy the Portable Holographic Interface Module but this will render the unit unusable in an emergency so discretion is advised before activating the unit. This has led to a Starfleet wide recall but due to resupply problems replacements have been delayed. ***
