3.2.4 Ensuring Operational Readiness
• Do not expose the device to direct sunlight, or extremely high or low temperatures.
The ambient temperature should be in the range of 0°C to 40 °C. Lower or higher
ambient temperatures will have a negative impact on the battery's life.
To ensure its readiness for use, the device runs a self-test to check the unit and the
battery. A self-test can be performed any time. An enhanced periodic test can be
performed in a defined interval (standard setting every 5 weeks) and at a defined time
(standard setting 12:00)
• Status OK: green blinking LED
• Device failure status: LED OFF.
If the device detects an error during the self-test, an alarm sound is activated.
An auto test can be executed anytime see paragraph 10.2.4 Auto Test.
