The Search And Rescue System - ACR Electronics TERRAFIX IO406 MHZ PLB Product Support Manual

6.3 Battery Replacement
Power is provided by self contained long life batteries with a five-year recommended replacement
cycle. See Factory Authorized Service Center for replacement.
The batteries (P/N 1099.2) must be replaced by the date indicated on the PLB. At each inspection,
check the time remaining until replacement is required. Batteries should be replaced if the PLB has
been activated for any use other than the self test.
Batteries should be replaced at an Authorized Battery Replacement Center for the warranty to remain
in effect (if the 5 year warranty has not expired). Services include: replacement of battery packs and
disposal of expired lithium batteries, gasket and O-ring examination and replacement if necessary,
lubricated gaskets and O-ring, air pressure test to ensure water tight integrity, and a full electronics
diagnostic check.
NOTE: This unit is a life saving device and all repairs and replacements need to be made by ACR or
an authorized ACR battery replacement center to ensure the beacon will perform properly when
called upon. Batteries can be replace in the field if necessary (replacing your own batteries will void
your warranty, contact ACR at 1-800-432-0227 for a replacement battery dealer nearest you),
however it is highly recommended to have your beacon serviced once you have returned from the
field to ensure the integrity of the beacon has not been compromised.
For the nearest location of an authorized ACR service center, call 1-800-432-0227 (toll free) or visit

SECTION 7 - THE SEARCH AND RESCUE SYSTEM
7.1 General Overview
The TerraFix™ 406 GPS PLB provides distress alerting via radio transmission on 406 MHz to
satellites of the COSPAS-SARSAT network and to the GEOSAR network that includes GPS latitude
and longitude coordinates when GPS data is present.
The message transmitted by the TerraFix™ 406 GPS is unique for each PLB, which provides
identification of the transmitter through computer access of registration files maintained by the
National Oceanic and Atmospheric Administration or other National Authority. Remember, if your
PLB is not registered, Search and Rescue (SAR) Authorities do not know who you are, or how to
contact anyone who might know anything about your situation (Refer to section1).
Once the TerraFix™ 406 GPS signal (406 MHz) is relayed through the LEOSAR and/or GEOSAR
network, SAR forces determine who is closest, then track the signal using the 121.5 MHz homing
frequency for intermediate and short-range location.
