Momentarily push the zoom control button to slowly magnify into the displayed scene. The X1, X2,
X4, X8 symbols (maximum zoom factor is dependent of model) will appear in the lower part of the
display.
NOTE:
Digital zoom allows distant objects to appear larger; however, the resolution will be compro-
mised.
NOTE:
Zooming does not affect the boresight.
NOTE:
Digital zoom and reticle color control help target detection and discrimination.
10. To align the barrel of the weapon, place the reticle on the desired target. To allow for the bullet’s
travel (i.e. bullet drop, windage, and the target mobility), use the boresight adjusting buttons.
11. To operate the Zeus in short-time activation mode, turn the switch to the STB position (standby). To
activate the Zeus, hold down the remote control button. Release the button to deactivate the Zeus.
CAUTION:
DO NOT leave the equipment activated when not in use.
3.3.2 BORE SIGHTING THE ZEUS
NOTE:
Zero the weapon prior to installing and bore sighting the Zeus.
Boresight the Zeus as follows:
1. Locate a target at the fire adjustment range (100m).
2. Turn on the Zeus.
3. Adjust the eyepiece and focus the objective lens to sharpen the image of the target.
4. Adjust the brightness of the display.
5. Select a reticle pattern.
6. Take aim by centering the reticle on the target and fire a series of shots (3-4).
7. Find the center of impact and measure (in centimeters) its vertical and horizontal deviations from the
center of the target.
8. Work out the values of boresight correction required to compensate for the measured deviation of
the center of impact from the center of the target. Table 3-3 contains examples of calculating bore-
sight correction values when firing at ranges of 100m.
9. Use the BORESIGHT MENU to apply corrections required to bring the center of impact as close as
possible to the center of the target. See Part 3.2.2 (Using the MAIN MENU).
NOTE:
Remember that the center of impact on the target shifts in the opposite direction from the
direction that the reticle shifts. To bring the center of impact to the right/left and up/down,
you must shift the reticle to the left/right and down/up, respectively.
