3.5.10.2 Operating Hints, Operating Errors
Values exceeding the limits are shown by the respective value flashing; they can be cancelled
using the key RUB OUT.
Values which exceed modulation range limits for AM, FM and sweep are also shown by flash-
ing; press the key ENTER and this values are automatically set to a permissible value.
Mistakenly input figures can be deleted using RUB OUT, provided the key ENTER has not been
pressed. This must be followed by a new entry.
ERROR display during operation means as follows:
Err 51 12C bus to EEPROM 1 defective
—, Err 52 12 C bus to EEPROM 2 defective
Err 53 12C bus to coarse attenuator defective
Err 54 IzC bus to stereo unit defective
Err 55 12C bus failure RDS
—'
Err 56
12C bus to IEEE bus interface defective
Err 62 phase-locked loop 2 doesn't lock
_
Err 63
phase-locked loop 3 doesn't lock
Err 66 centre frequency of sweep not settled
i Err 70 level correction doesn't work correctly
Err 75
calibration of modulation frequencies impossible
,,._ If error messages 51 to 56 appear (with the exception of error 53) , the instrument may still
continue to operate but without the function shown.
If errors 62 to 66 appear, it is no longer possible to work in the frequency range of the respec-
live phase loop.
Error message 70 shows that the output level is no longer within specifications, continued
operation is thus pointless.
