3.7 Battery Witness Seal Life
If your beacon flashes an initial red LED at the beginning of the Self- test, this indicates that your electronic
witness has been broken and you have used more than 1 hour of battery life for the PLB-350A models and
more than 1 hour 20 minutes for the PLB-350B models. While the beacon will still operate normally in a
distress situation, ACR strongly recommends you have your battery replaced and the electronic witness reset
to ensure that you will have 24 hours of battery power.
3.8 GPS Testing (GNSS Self-Test)
This test is NOT required as 100% of all GPS receivers that leave ACR have been tested to ensure they
perform correctly. However, if you would like to ensure your GPS receiver is working, please follow these
instructions very closely.
CAUTION: For PLB-350B models, the following test should not be performed more than twelve times
during the life of the battery pack. Once this GPS testing feature reaches 12 times, the feature will be disabled
by internal software.
NOTE: The GPS receiver is located under the bottom front portion of the case. It is imperative that the receiver
is not obstructed during Self- test or activation to ensure that the GPS receiver is acquiring your latitude (LAT)
and longitude (LON) position. This test must be performed outside with a clear view of the sky.
Press the self-test button for greater than 5 seconds. Observe the beacon for the entire GPS test. A BEEP and
green LED will indicate that the GPS has been turned ON. The beacon will BEEP every 5 seconds and the
GPS will remain ON until LAT/LON coordinates have been obtained or until 2 minutes have elapsed. If good
LAT/LON data has been obtained, a single 406MHz test burst will be sent out with location data and the GPS
will be turned OFF and the green LED will light for at least 3 seconds along with a long beep. This LAT/LON
data is not saved for use. The green LED indicates that the GPS is functioning properly and that the beacon is
in a location or environment where it can receive the necessary signals from satellites. If the GPS does not
acquire good LAT/LON data, the GPS will turn OFF after 2 minutes, followed with a RED LED light up for 3
seconds along with a long beep, and no 406MHz burst sent out.

SECTION 4 – ACCESSORIES
4.1 Multi-Function Belt Clip
The TerraFix™ 406 and MicrOFix™
12
come standard with a multi-
functional belt clip. To install the clip, simply align the bottom tabs on the
clip with the insert holes located on the bottom of the beacon. Snap the clip
in place by pressing the top of the clip so that the two top tabs engage in
the two insert holes on the top of the beacon (see Figure 4). To remove the
clip, push up and back on the top tabs one at a time to disengage the clip
from the beacon.
The belt clip has been designed to accommodate your extreme
adventures. You can secure your beacon directly to backpack webbing
straps, life jackets or belts to ensure the beacon is close at hand. ACR
recommends that you secure your beacon someplace on your person that
is easily accessible in case of an emergency for rapid activation. Ensure
the beacon is secured firmly and is protected before heading out to avoid
damage or loss.
