EQ33 Introduction and safety summary
1.2 Safety summary
Precaution:
Do not open the equipment, only qualified persons should work
inside the equipment. If the glass in the screen breaks, be careful not to get cut
on the sharp edges of the glass pieces.
Power source, fuse and power cable:
Check that the DC power supplied to
the unit is within the range of 10 to 32 volts. Note that the appropriate fuse
must be employed (see the fuse rating in section 9.10 Specifications). Ensure
that the power cord is firmly attached.
Grounding:
To reduce electrical interference and risk of electrical shock,
properly ground the unit to the ship’s ground using the ground screw at the
rear of the unit. Good grounding should also be exercised for any equipment
connected to the EQ33.
Quality service personnel:
The EQ33 is sealed and does not contain any user
serviceable parts. Opening of the unit will void its warranty. Touching electri-
cal parts inside may cause bodily harm. If the unit is not working properly,
check sections 9.7 Preventive maintenance, 9.8 Repair and service, and 9.9
Troubleshooting. If your EQ33 requires servicing or repair, call your author-
ized SIMRAD dealer.
Glossary of terms:
If you have never used an echosounder before or if you are
unsure of how a term is used in this manual, then turn to Appendix A - Glos-
sary of terms.
Default settings:
All user implemented data in the EQ33 can be erased by
making a reset of the unit and thus return to factory default settings.
