P3 question on the noise floor

[Ross Biggar]

Jim, in his reply stated that the level on the screen should go down to -150dbm.
As I stated in my email, whenevr I try to change the level, It comes up with the Boot loader screen,
Not a lot of help.

Ideas please as I need to lower the noise floor on the P3.

Thanks
Ross

Ross,

I think I may have missed the original message.  Anyway, if I understand
right I would suggest doing a configuration reset.  (Hold the
MENU/LABELS key wand then hold the POWER key until the Configuration
Reset message appears on the screen.)  If that doesn't work you might
try upgrading P3 firmware.  There have been some changes in the way
reference level data is saved in EEPROM.  The latest version is 00.36.

Ross the only way I can simulate that behavior on my P3 is by disconnecting the P3 to K3 cable.  Doing so causes the bootloader screen to come up immediately when trying to do a ref lvl adjustment.  You may have a loose cable or pin not making connection?
