ZONE ALARM
The zone alarm consists of a
bar that appears on the right
side of the screen. Any echo
that appears on the screen
between the top and bottom of
the zone alarm’s bar will “trip”
the zone alarm.

Note: The zone alarm isn't
available in the Windows mode.

To set the zone alarm, press
the MENU  key. Now press the key next to the “Adjust Alarms” label.
Finally, press the key next to the "Set Zone Alarm" label. A screen similar
to the one shown below appears.

The zone alarm bar shows on
the right side of the screen.
Use the arrow keys to move
the bottom of the bar higher or
lower. To move the top of the
bar, first press the key next to
the “CHANGE TO UPPER” la-
bel. Now use the arrow keys to
move the top of the bar higher
or lower. When you have the
zone alarm bar set as desired,
press the CLR key to erase the
menus.

The above steps automatically turn the zone alarm on if it was off. To turn
the zone alarm off, press the MENU key, then press the key next to the
"Adjust Alarms" label. Now press the key next to the "Turn Zone Alarm
Off"label at the bottom of the screen.

Normally, the zone alarm bar disappears from the screen after you make
adjustments. To leave the zone alarm bar on the screen all of the time, see
the "Display Zone Alarm Bar" section in this manual for instructions.
