Important Safety Tip Regarding the 5k

Post by **batdude** » Tue May 09, 2006 11:59 am

BE VERY VERY WARY OF SWAPPING VOCONS ON THE 5k.

I swapped a vocon in two radios @ work due to a suspected problem with a radio (it was dropped and had intermittent audio in IMBE).

The suspect (bad) radio had firmware 5.xx in it.

The donor (good) radio had firmware 7.xx in it.

Upon placing the donor vocon in the suspect radio, no faults were found with the RF side of the suspect radio (i.e... NFF - no fault found)

When I put the old (suspect) vocon back into the suspect chassis and booted it.....

I was greeted with FAIL 001.

HRMMMM.

Seems as though the vocon will update the Tuner (i.e. RF BOARD) firmware upon first boot when it sees a new RF deck. This update will prevent the RF board from communicating with it's orignal VOCON.... and there is no way in the field to recover this fault.... it has to go to the depot.

Therefore,

DO NOT JUST RANDOMLY SWAP VOCONS AND RF BOARDS IN THE 5k.

They just love to kill the fun out of future play.

That's no fun - one of the good "poor man" troubleshooting tools in legacy radios was to swap boards to locate the fault. grrrrrr
