SHOCK HAZARD
Do not connect or disconnect the tow cable from the
towfish or the TPU when power is on. Failure to follow this practice may
result in personal injury and will damage the towfish or the TPU
electronics, or both.
CAUTION
Serious damage to the towfish electronics may occur if the
towfish is operated on deck for periods longer than fifteen minutes.
Between periods of operation, let the sonar cool for fifteen minutes. In high
temperature climates, protect the towfish from direct exposure to the sun prior to and
during operation.
