Page 44: System Time
The DRS is capable of naming the log-files based on the current date and timestamp. Therefore, the system’s time has to be set in advance. This is usually done before shipment but you are free to set it anytime, e.g. to adapt it to your local time zone. ©2022 Drone Rescue Systems GmbH 9/19... -

Alternatively, an Emergency Trigger Device (optional accessory) with SBUS communication can be used to trigger the parachute deployment. In this case an SBUS signal is used instead of a servo signal.

Page 53: Takeoff
If the DRS does not detect the takeoff, you must land the UAV because the automatic deployment function is inactive. Switch the power off, wait 10 seconds and repeat the start procedure. If a failure persists, inform Drone Rescue Systems GmbH or it’s reseller and provide the logfile for failure analysis. Timed Deployment via File If your application setup does not offer a possibility to use the manual deployment trigger, then you can use the "timed deployment"... - Page 54 Do not take off when the timed deployment feature is active because the parachute will be deployed and the motors will be stopped (if configured so) when the timer runs out. If the UAV is in the air in this moment, it will fall down. ©2022 Drone Rescue Systems GmbH 19/19...
