306 Radio dead

I have a 306 meridian 1999, on which the battery was disconnected.
After re-connecting the battery the radio will not switch on. I am not
even being prompted to enter the code, which I do have. I have checked
the fuse, no 24 according to the Haynes manual, and it appears to be
fine. Also all other electrical components are working.

The handbook for the radio calls it an "Audio RB1", there is no
manufacture's label but I believe it is made by Philips. In the
handbook it does mention that the radio will be permanently blocked
after 14 incorrect attempts to enter the code. But as I say I didn't
even get one. But wondered if disconnecting the battery has somehow
caused it to go into a permanently blocked state. In which can it be
unblocked?

I do not have the necessary tool to remove the radio, din keys, and to
be honest changing a plug is about the extent of electrics knowledge.
But I was wondering if there is something I have missed or could try?

 

on some radio's there is also a fuse on the rear of the radio itself,
usually a 10 amp, this may well have blown.

The standard radio in my wife's 306 meridian (V reg) doesn't use DIN
keys as I know them to get it out, but the older system (2 holes on
either side just the right diameter for coat hanger wire. Insert an
inch or so and pull out the radio. When I removed ours it took a
surprising amount of pulling even once the clips were disengaged.

Some radios (can't remember about this on) also have a 0.5A or similar
fuse in the permanent live line - worth a look.

Chris,

My 306 is also a V reg and your description of the radio, which is a
factory fit, sounds the same as mine, i.e. two holes on either side.

I'm sure I got a wire coat hanger somewhere.

Thanks to both of you for pointing out that there maybe another fuse.
Although I don't undertand why, when there is one in the fuse box. But
as I said electrics is not my strong point.
