INSTRUCTION DIAGRAM FOR CONNECTING 6 VOLT BATTERIES TO PORTABLE BIRDTRAP
Use two six volt lantern batteries with spring terminals. Connect as shown above.
BATTERIES
All Models operate from the 12 volt system on your boat or a 12 volt dry cell source. The dry cell source may be two 6 volt cells connected in series.
Replace or charge the batteries when you notice that the dial motor has slowed down. This indicates that the battery voltage has fallen below 10 volts and this low voltage will cause the dial lamp to flash at less than the actual depth.
NOTE; A weak battery will sometimes cause the lamp not to flash even though the motor still runs.
NOTE: If the lamp on your depth sounder does not flash or flashes intermittently, check your battery connections. Very often a battery will operate your trolling motor or crank your outboard motor, but still not have enough voltage to operate the depth sounder. This is due to the fact that trolling motors and starter motors are current sensitive whereas the depth sounder is voltage sensitive.
