Environment: Provide good ventilation to prevent overheating.
CAUTION: Do Not Remove the Transducer Cable
Removing the transducer cable from the sounder module while
power is turned on can cause sparks. As with any electronic
device, be sure the sounder module is mounted where it is well
ventilated and free from gasoline fumes.
1.4 Mounting the Sounder Module
The DSM can be mounted either above or below deck using the supplied
hardware. To allow for ease of cable connection, mount the sounder module so
that the cables hang below the unit.
