NOTE 1: Tone is a CW burst whose frequency is noted on the supplied Configuration Sheet.
NOTE 2: Battery Indication: When a DISABLE command is received at the Acoustic Release the
acknowledgement replies indicate battery condition rather than tilt. The PORT returns 6
pings for a full battery with successively lower energy for 5, 4, & 3 pings. When down to 2
pings the battery is almost drained. If you have an indication of 2 pings then it would be
prudent to release the unit and recover unit to change out the batteries.
Octal codes representing F1 – F4 are shown below. A diagram showing the timing of
an octal code is also shown below.
