This overrun may occur for example in the “Notes” menu. Move the cursor
towards the right hand side of the display to recover characters which have
“overrun” to the right. You can then move back one character at a time in the
display by pressing the cursor key. In the case of an overrun to the left, the
cursor jumps back to the first input position when the button is kept pressed.
Acoustic Messages
Some signals are indicated only acoustically in addition to the only optically

Tone Signals Used
Two tone frequencies are used to distinguish between the individual mes-
sages. High tones (frequency approx. 1200 Hz for positive messages) and
low tones (frequency approx. 400 Hz) for negative messages.
Four different tone lengths are possible depending on the programming:
long approx. 1 second
medium approx. 0.35 seconds
short approx. 0.1 seconds
very short (click) approx. 20 milliseconds
