Design change
On sonars shipped from Simrad before August 2003, the
APC10 Sonar Processor Unit is used. This unit is also equipped
with an “on/off” switch behind a front panel. It has also an
additional “master on/off” switch on its rear panel. Instead of
disconnecting the mains plug, this switch can be set to “off”.
Stop procedure
1. Press the Up button on the Sonar Operating Panel to hoist
the transducer to the upper position.
- The green LED next to the button will flash, and an
audible signal indicates that the transducer is hoisted.
When the upper position has been reached, the LED
will illuminate continuously, the audible signal stops,
and the upper button in the Status menu shows:
Transducer: UP.
2. Press and hold the Power button approximately two
seconds to switch off the sonar.
3. Check that the green LED next to the On/off button
extinguishes.
4. Press the Power button on the display monitor to switch it
off.
Warning: If the sonar is switched off uncontrolled with the
transducer lowered, the transducer must be
raised by means of the hoist/lower switch in the
Motor Control Unit, or with the hand crank.
