If, on the display panel, the blinking sign (-) appears in the middle this means that battery voltage decreased below permissible level ( 10,3 V). If it goes while the button START is pressed it is advised to lower the power of fishing in order to catch for some time yet. If the (-) is lighting constantly then you should stop electrofishing and change or charge the battery.
Proper operation of electrofisher while the battery is lower than 10 volts is not guaranteed.
Additional remarks and pieces of advise while working with electrofisher SAMUS700.
ATTENTION!! If the power supply is disconnected then the display unit is reseted and time is zeroed, also Ampere-hours indication and it is necessary to insert password again to switch a device again.
While electrofishing please try to work with visible functions P or I ( right side) in order to have control over power of electrofishing. Given parameters interdependent and it is advised to observe them from time to time. For instance good results are obtained while fishing on J=10-20 Amperes and F ( frequency) 40-50 Hz.
For the first switching try to control(regulate) parameters on OFF-START mode. The consumed current should not exceed 0,1 A.
If the fish is sinking, swims away on deep water or from landing net, please try to decrease power of electrofisher by regulation of impulse duration. If this does not help try to decrease power regulating frequency.
If the fish gambols, makes circles in the water while going to landing net then raise the frequency.
