SECTION 3 – OPERATION
The PLB350 beacon models are designed to be manually deployed and activated. They are only to be
activated when all other means of self-rescue have been exhausted. When properly registered as required, the
activation of the beacon tells Search and Rescue who you are, where you are, and that you are facing a life
threatening situation.
Note that the keypad functions for all PLB350 models are the same and in the same location. See Figure 2.
NOTE: Reference to GPS functionality in Figure 2 applies only to those PLB-350B models that are equipped
with an internal GPS system.
3.1 Activation (406 MHz and 121.5 MHz)
To activate your beacon in a distress situation, follow these steps:
1) Unfasten the antenna from the case.
2) Move it into the upright position (see Figure 3 below).
3) Depress the ON/OFF button for 1 full second.
You will hear a BEEP and your beacon is now activated. While transmitting your distress signal, the red LED
will flash once every 2 seconds alerting you that your beacon is active. An additional BEEP will sound every
time your beacon transmits data to the satellites (roughly every 50 seconds).
