Keyboard/Display Screen

❏ Key Tone: Low, Medium, High

Sets the frequency of the speaker for key clicks.

❏ Key Click: On or Off

When “On” is selected, an audible beep is sounded when a key is

pressed. When “Off” is selected, there is no sound.

❏ Auto-Pan: Enabled or Disabled

When auto-panning is “On,” the screen pans as the cursor moves

beyond the visible window. When it is “Off,” the screen does not pan

when the cursor leaves the visible window. You can move around the

screen manually using the GOLD key + arrow key combinations on

the keyboard. (Refer to Display, Section 2, for more details.) You can

toggle auto-panning on and off from the keyboard by pressing the

GOLD key + <Ins>.

❏ Heater: Auto or Off

The heater setting should be set to “Automatic” when temperatures

are at or below freezing and the display begins to get sluggish. When

the heater setting is “Auto,” the Allegro monitors the display

temperature every five minutes. If the temperature is less than -3° C

then the heater is turned on. When the temperature is above -3° C, the

heater is turned off. The Allegro does this automatically. When the

heater is on it uses 250 mA of current. When the heater setting is

“Off,” the heater is always off.
