Troubleshooting
This chapter is intended primarily to help you recognize some common error
states which can be corrected from the 300 front panel, or by simple means such
as cable replacement. Any error states which are not covered here should be
referred to your local dealer for service by a qualified technician.
In a low-voltage, or "brown-out" condition, the 300 will freeze in its current state.
None of the controls will have any effect. When power returns to a normal level
the unit will reset itself as though it had just been powered on. If the unit does
not reset itself, turn the power OFF, then ON to resume normal operation.
Temperature extremes may cause the 300 to exhibit unpredictable behavior. If
the unit as been subjected to temperatures below 32
°
F (0
°
C) or above 95
°
F
(35
°
C), it should be turned off and allowed to return to normal temperature
before use. The unit may be damaged by exposure to temperatures below -22
°
F
(-30
°
C) or above 167
°
F (75
°
C), or by exposure to humidity in excess of 95%. If
a unit exposed to such conditions fails to operate after it returns to a normal
operating temperature, contact your local service representative.
