Entry of invalid key presses or invalid values
If the entered value exceeds the rated range, a beep sound will be heard. If the entered value is below
the lower limit, the instrument will automatically change the entry to the lowest possible value. If
the entered value exceeds the upper limit, the instrument will automatically revert to the maximum
value.
Example: When trying to entering 90MHz in a model 4086 (80 MHz max), a beep will be heard and
the value will be forced to 80 MHz.
Invalid keys: A beep sound will inform the user that the key entry is invalid. The instrument will
simply ignore the key pressed.
Example: Key【-】is pressed when trying to enter a frequency value. The instrument will ignore the
entry and respond with a “beep” sound.
