2-50 Services and Feature Description
6866588D21-D Chapter 2 - MTP850 Ex/MTP810 Ex Product Information Manual March 2009
The Man Down feature is based on a small sensor with low power current consumption. The sensor
is interfacing directly to the terminals processor.
If any of Man Down settings is enabled the sensor performs a self test during terminal power-up. If
the test fails, the terminal notifies the user with specific audio tone and status icon.
The user is also notified by specific audio tone and status icon when the MD device detects a failure
during the activation of the feature.
If user deactivates the feature after the sensor failure is detected, then the icon disappears and the
tone is no longer emitted.
