The readout time varies with the complexity of the recording configuration.

During tape playing, the power cord was unplugged.

Cassette record protect tabs are removed.

The path between the Remote Control and the sensor on the Unit is blocked.

The batteries have lost their charge.

The built-in microprocessor has malfunc- tioned due to external electrical interference.

Action
