6. April-2013 OpenStage M3 Use Cases – Examples Page 6 Health Care Mobile DECT telephones are a cost effective healthcare communication solution that gives hospital staff the needed degree of mobility. Clinicians have direct connections to one another, as well as to patients. The integrated alarm features generate automatic alerts in man down scenarios, sending notification to an alarm center for immediate help. Combined with device location support makes for improved timeliness when responding to emergency situations. Manufacturing Industrial service technicians require mobile telephone communication during maintenance cycles. The excellent acoustics of OpenStage M3 telephones make for improved voice communication and therefore improved productivity even in the loud surroundings of the production line.

7. April-2013 OpenStage M3 Use Cases – Examples (continued) Page 7 Mobile Communication in Extreme Industrial Environments By law, special communication equipment is needed in environments where potential explosive gases or dust can be released. Employees working in these circumstances, such as security guards, need reliable, robust and intuitive communication devices when mobile. Thanks to OpenStage M3 Ex Plus integrated automatic alarm option, staff do not require an additional escort. For example, if explosive gas is leaking and a guard faints, the motionlessness is automatically announced as an alarm signal to the alarm center. The alarm center is able to promptly identify where the guard is located and aid can be directed to the guard. Responding personnel can then place emergency services calls with the OpenStage M3 Ex Plus. Copyright © Unify GmbH & Co. KG 2013. All rights reserved. December 2013 Page 7
