Troubleshooting

This chapter is intended primarily to help you recognize some common error states which can be corrected from the PCM 80 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 PCM 80 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 PCM 80 to exhibit unpredictable behav- ior. If the unit has 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.

Low Voltage

Overheating

The PCM 80 doesn't respond to MIDI Program Changes.

Check Receive control at Control mode 3.1 and make sure it is set to On. Check the MIDI Channel selected as well as the MIDI Channel of the transmitting device. Make sure that Pgm Change at Control mode 3.3 is set to On. Also check MIDI In/Out connections between the units.

MIDI Program Change numbers are off by 1.

The PCM 80 transmits and recognizes ProgramChange messages 0-127. MIDI devices which transmit 1-128 rather than 0-127, will be off by 1. Simply adjust by 1 when working with such devices.

The PCM 80 doesn't respond to SysEx commands.

Check the SysEx setting (and the Device ID selection) at Control mode 3.7.

The PCM 80 does not transmit SysEx Automation commands.

Check the Automation setting (and the target device ID selection) at Control mod 3.4.
