* Error 6
This test is carried out every time the 9814 is switched on regardless of the IEEE ad-
dress. If the calibration factors are corrupted ERROR 6 will be displayed. To clear this
condition, run the self test with the calibration key plugged in. This exercise leaves the
cal ram empty so re-calibration is required. (see section 8).
If ERROR 6 persists, then change the non-volatile RAM.
NOTE: Running self test with the calibration key plugged in will result in the loss of cali-
bration data.
To exit from self test mode, turn the 9814 off, set the unit address on the IEEE switches
and switch on again.
