CAUTION:
Removing the transducer cable from the rear of the DSM250 while the
sounder module is powered on can cause sparks. Only remove the
transducer cable after power has been removed from the DSM250.
If the transducer cable is accidentally removed while the DSM250 is
powered on, remove power from the sounder module, replace the
transducer cable, and then return power to the module. As a safety
feature, the DSM250 only recognizes that the transducer is connected at
power-up.
