Alarms
The Model 960 continuously monitors itself and sounds
an alarm if it detects something wrong. The alarm is a
beep that is on for one second and then off for nine
seconds. When the alarm sounds, the display shows
the letters “Err” with a number from 1 to 4. The table
below lists the Err numbers, a description of each error,
the cause of the error, and the solutions. To silence the
alarm, press any button on the control. If the error still
exists, the control will go back to the alarm condition
after 30 seconds.
