Time will not set and erasing music

[Alan Stewart]

Hi.

My JB7 will not display the correct time. I have replaced the internal CR1220 battery however the display simply reads 0:00 when started. Going into settings and changing the time results in it just going back to 0:00 after the final push of the knob. It will not change. I have tried two different new CR1220 batteries but no difference. Any idea's

Also talking about settings, I want to remove all the music in one go and redo . There is supposed to be a 'Maintenance' section within the 'settings' menu that allows me to do this. however on my JB7, there is no 'Maintenance' section within the 'settings' menu. My manual shows the menu structure and there is no 'maintenance' section listed in the manual either.

Was this a software update. if so, where can I get this update?

Thanks,

Alan.

Hi Alan,

I think that your JB7 might be the first generation model so the note below might be relevant.  There was a JB7 software update released some years ago, but I have not been able to locate a copy of this software so far.

Below is an extract from a Brennan JB7 support document that I found on the Brennan website.  The first generation JB7 units did not have a 'Maintenance' menu but rather it had a hidden menu as described below.  So try the procedure below, in particular the 'Map Disk' option.

"How it works

Secret Menu

We developed a couple of utilities for fixing occasional problems - like mistakenly loading all CDs with compression disabled.

These were originally in a hidden menu but we realised thats a bit like not telling the passengers where the lifeboats are - so the most recent JB7s have the functions in the Maintenance menu under Settings.

If you have an older JB7 you can access the hidden menu by putting one finger on the back button and then press the next button (still keeping the finger on the back button).

There are a couple of functions - that we use to tidy up the hard disk - that you might like to know more about.

Cleanup - fairly quick - often sorts out problems after USB load or not compressing or with Browse albums.
Map Disk - very slow >12 hours for a 320G - this will test for and sort out problems caused by bad sectors on the hard disk. We use this if the JB7 ever displays Disk Error."

With regard to the setting time problem, I suggest the following procedure.

1.  Just before midnight power down the JB7.

2.  Open the JB7 and remove the CR1220 battery and wait for 1 minute, then re-insert the battery.

3.  At midnight power up the JB7; this should set the clock to 0:00 and should then be correct from this point on.

If the above proces works, then post back here and then we can look at deleting the existing music 

Let us know how you get on.

Regards,

Peter.
