Chapter 1-2 EQ44/54 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.
The lifetime of the internal battery is minimum 5 years.
If not exchanged
before it goes flat, all data in the unit’s memory will be lost.
We strongly
recommend that you have the battery exchanged at your local Simrad work-
shop max. 5 years from date of purchase.
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 11.10 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 EQXX.
Quality service personnel:
The EQXX is sealed and does not contain any
user serviceable parts. Opening of the unit will void its warranty. Touch-
ing electrical parts inside may cause bodily harm. If the unit is not working
properly, check sections 11.7 Preventive maintenance, 11.8 Repair and service,
and 11.9 Troubleshooting. If your EQXX requires servicing or repair, call your
authorized SIMRAD dealer.
Cleaning:
Do not use any kind of strong solvents e.g. spirit, alcohol, gasoline or oils.
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 EQXX can be erased by
making a reset of the unit and thus return to factory default settings.
Software:
The software version of the EQXX (see start-up display) should
always be informed in a service situation.
