Black Diamond Equipment announced a voluntary recall of most Black Diamond and Pieps avalanche transceivers in 2022. This page explains how to test the Pieps DSP Sport and DSP Pro transceivers. Learn more about the recall.
Please send me a note, too, if your transceiver fails these tests.
( Black Diamond's official instructions on testing your transceiver.)
The "release tab" on some DSP Pro and DSP Sport transceivers can fail which will allow the Off/Send/Search switch to move to the Off position. Read the details here.
