This beacon contains two (2) lithium metal battery packs that are less
than 2 grams each. They are not classified as Hazmat for transportation.
Prior to shipping beacon for service, alert your carrier about the
batteries contained in this equipment to make sure they properly label
your package. Call ACR‟s Technical Service department at +1 (954)
981-3333 for proper shipping instructions or visit the ACR website in the
Support section entitled "Hazmat, MSDS Sheets, & Info".
3. Self-Test
ACR strongly recommends performing the Self-test once per month,
or at least two weeks prior to a trip, to allow enough time for service,
should your beacon require it.
A Self-test is initiated by holding the Self-test button for at least ½
second and less than 5 seconds. Your beacon will sound an initial
"beep" and flash the green LED to signify the test has begun. Four more
beeps will follow. The green LED will flash a second time to indicate
that the Self-test was successful.
NOTE: The "beep" is a very high pitch sound that some people are
unable to hear. Watching the LEDs may be more useful to you.
Components
synthesizer, RF power/battery, GPS header (if equipped).
If a red LED flashes at the completion of the Self-test, your beacon has
failed. Repeat the Self-test. If the failure persists, contact ACR
Electronics or an authorized Battery Replacement Center to have your
beacon serviced.
NOTE: During a Self-test your beacon will send a 406 MHz signal coded
as self-test to the satellite system. The 121.5 MHz homing signal is
inhibited during Self-test. This allows you to test your beacon any time
during the day without causing false alerts.
