Angle Determination 16 February 2016 ATP 3-09.02 5-7 Figure 5-7. Angle unit selection. 5-15. After the ANGLE UNIT is selected the next step is to set the AUTOMATIC POWER CUT-OFF selection (see figure 5-8). The 3 available options are OFF (which disables automatic cut-off for continuous operation), selecting 10’ will automatically shut the instrument off if left unattended for 10 minutes, selecting 30’ will automatically shut the instrument off if left unattended for 30 minutes. A buzzer will sound 5 times, a minute before the power cuts off. Unattended means, no key operation, or no changes in horizontal or vertical angles. To change the setting, depress the RESET key and the position of the highlighted black square will be switched over, depress the HOLD key to fix the setting and proceed to the next setting. Figure 5-8. Automatic power cut off 5-16. The final step in the Initial Setting sequence is the TILT Telescope setting (see figure 5-9 on page 5- 8). Be careful not to insert your finger between the telescope and the instrument trunion when rotating the telescope. Using the vertical clamp screw, loosen the telescope and rotate slowly till the instrument beeps once. The LCD will then revert to the initial start-up screen.
