SHIP’S MAINS VOLTAGE. PRESS R/B KEY TO 
TURN OFF ALARM.

This message blinks at the screen center and the 
buzzer sounds when the voltage supplied to the 
transceiver unit is excessive. Transmission is 
stopped if the equipment is transmitting, to pro-
tect the transducer and transmitter power section 
from damage. 

Silence the buzzer with the 

R/B AUDIO

 key, 

retract the transducer and turn off the power. 
Have a qualified technician check input voltage.

Transceiver unit

<<NO RESPONSE FROM TRANSCEIVER 
UNIT!! >> TURN OFF AND ON POWER AGAIN, 
OR CHECK POWER LINE TO TRANSCEIVER 
UNIT. PRESS R/B KEY TO TURN OFF ALARM. 

This message blinks at the screen center and the

SHIP’S MAINS VOLTAGE. PRESS R/B KEY TO 
TURN OFF ALARM. 

This message blinks at the screen center and the 
buzzer sounds if the +B voltage of capacitors in 
the transceiver unit can not be charged to prede-
termined voltage within the specified time. 

Press the 

R/B AUDIO

 key to silence the buzz-

er. Have a qualified technician check the set.

<<OVER TEMPERATURE!! >> RETRACT 
TRANSDUCER AND TURN OFF POWER. 
PRESS R/B KEY TO TURN OFF ALARM.

This message blinks at the screen center and the 
buzzer sounds when the temperature in the pow-
er supply block has exceeded 85°C;.

<<TRANSDUCER NOT RETRACTED!! >>CUT 
OFF POWER LINE TO MONITOR UNIT AND 
HULL UNIT. PRESS R/B KEY TO TURN OFF 
ALARM.

This message blinks at the screen center, the 
buzzer sounds and the LEDs above keys blink if 
the transducer is not raised within 15 seconds 
(800 mm stroke) or 18 seconds (1100 mm 
stroke) after pressing the 

 key. 

Press the 

R/B AUDIO

 key to silence the buzz-

er. The reason may be the transducer is tangled 
in the net or its shaft is bent or the motor bleaker 
is off. Try raising it from the hull unit as shown in 
section 9.12.
