User's Manual

A function that sets a guard zone of any distance and any angle range, creating alarm tone

when either echoes above a certain level exist (IN MODE) or no echoes exist(OUT MODE).

When GZ is operated with soft keys, guard zone settings and ON/OFF settings can be

conducted, but the mode (IN or OUT) is to be set in the menu.

Note: Refer to "5.5.2.2 Guard Zone (GZ)".

(1) When the "GZ" key is pressed, the present mode setting will be displayed on the left side of

the screen as GZ IN. A small cross cursor for setting the guard zone will be displayed at the

screen center while "SET CENTER POINT" is displayed at the bottom, activating a guard zone

setting state.

(2) Use the up-down/left-right cursor keys to move the cross cursor to the center of the warning

zone to be set, and press the "ENT" key.

(3) From the cross cursor position set in (2) above as the center, expand the guard zone in the

direction of the distance with the up cursor key and in the direction of the angle with the

right cursor key, thus making the form of a fan. To make the warning zone smaller, operate

the down cursor key (in the direction of the distance) and the left cursor key (in the direction

of the angle).

(4) After the setting the guard zone, finish by pressing the "ENT" key.

Press the GZ key twice to cancel the guard zone function.
