Self-test
International regulations require that Self-testing of the PLB should only be carried out
in the first five minutes of any hour.
Self-test verifies operation of the PLB by checking key features including battery
voltage and 406 MHz and 121.5 MHz alert transmitters.
Important
Each self-test draws small amounts of energy from the battery pack. Unnecessary
testing of the PLB may subsequently reduce the run time of the PLB in an emergency.
On average, the PLB should only be self tested 12 times per year, or a total of 60
times across the 5 year battery lifetime.
To operate self-test, use the Test/OFF button, located under the flexible handle of the
red anti-tamper cover.
