HF/LF

Why is it that when you select high frequency on one unit, and select low frequency on another unit with different transducers it will not match in the lower left corner data box to the reading on the frequency screen? In other words the frequency selection does change to the proper frequency setting, but doesn't show the proper HL/LF on the frequency page.

Was this fixed in the latest update?
 
Capt David,
May I ask what system you are using, TZT/DFF1 or TZT2?

Capt. David,
So you have four TZT2's? How many transducers do you connected?

Let's say that you have a simple system, two TZT'2 but only one transducer connected. The TZT2 that the transducer is not connected to should be placed in the stand-by mode and the sounder source switched to the TZT2 that the transducer is connected to. Now if you change from HF to LF on one display, the other display will follow. If you display a LF/HF split screen both will be the same. Now if you have four displays and two transducers, the two displays without transducers need to be placed in the stand-by mode and the sounder source changed to one of the displays with a transducer connected. Hope this helps.

Hello Snips,

I have two transducers connected.

3 units are set to the same source, and 1 unit is set to another source using dff1-uhd.

If you tap the screen and go into the frequency screen and select hf or lf frequency it changes to that frequency properly and displays the selected choice in the data box on the lower left
ex 7.9 ft
HF

Now if you go to the second monitor which you are using with the DFF1-UDH, a different transducer, and the source is set properly you select a different frequency because you don't want both transducers networked in the system interfering with each other. Now this unit you set to HF, while the other units are set to LF.

All units are now showing the correct depth, and frequency on their respective screens, but now go back and tap the screen and bring up the frequency page and the units will change to the last selected HF or LF selected even though the frequencies haven't changed.

Please bench test this and you will see that you wont have hf and lf activated properly on the frequency page of all units even though the transducers are set properly to the HF/LF you selected.

After you set all units to your choice of HF and LF go back and check the frequency page of each unit and you will find that the units will change to the last selected frequency.

I hope I made this clear. You need to activate two or more units with two different transducers at the same time using different frequencies between them to prevent interference. Set the units to opposite frequencies, and the frequency page will switch to the last selected in the opposite unit. It will switch from hf on to say hf off if that was the last change on another unit. the frequencies are correct but the HF on off, and LF on off change and are incorrect. It doesn't affect the frequency choice but it is wrong as 1 unit will always show the opposite.

Thanks you
 
Understand.

This was a minor software bug reported to Japan a few weeks ago from our East Coast tech support. It will be addressed with the next software release. The indication is wrong because it is confused between the two sounders but they are operating correctly. You can go into the menu and reselect the Freq (HF/LF) and it will correct what is shown in the lower left. I appreciate you reporting it.
