The Yamaha C24 recorder has a firmware built-in timer that allows a single repeated recording slot cycled over the 24hrs.
It also allows to start the recording depending on the received level at the hydrophone.
Our RASP 12 - C24 includes a microSD 8GB memory card and a simple modification giving a double AA 1,5V battery pack.
Batteries must be correctly inserted following the scheme on the battery holder.
This is extremely important.
Both the recorder and the battery pack must be inserted in the canister using the provided net sack.
