Monitor Low mode
This mode is identical to the Monitor High mode except that the speaker
volume is lower.
NOTE: The ARX-50 reverts back to Alarm mode after 15 minutes in
Monitor High mode.
Training mode
Operation in Training mode is identical to the live radio beacon detection
mode.
In Training mode, the ARX-50 receives a special training frequency
(typically 121.65 MHz or 121.775 MHz). This allows users to become
familiar with the operation of the ARX-50 by using a special training beacon
operating on the same frequency. This way, local Search and Rescue
authorities are not notified.

mode.
Activation and alarm indicators
The ARX-50 is a fully automatic monitor/receiver. In Alarm mode, once the
ARX-50 detects a signal, a loud audible alarm will sound and a bright red
LED will flash.

Signal strength meter
The eight LEDs on the signal strength meter are capable of indicating
sixteen levels of received signal strength.
The signal strength meter provides the user with an indication of how far
away the 121.5 MHz signal might be. The higher the LEDs are illuminated,
the stronger the 121.5 MHz transmitted signal is, and the closer the signal
is relative to the ARX-50.
The reverse is also true: The lower the lit LEDs are, the less signal
strength, and the further away the beacon is relative to the ARX-50.
NOTE: The signal strength meter may display a low level of activity any
time that the ARX-50 is on. This is not to be mistaken for detection of a
121.5 MHz beacon transmission.
