LP 028 DAGR OPERATIONAL CHECKOUT Ref Para 18.3 Operational Checkout a.Inspect the DAGR [and external cables and equipment] for damage and/or missing parts. (Refer to the parts list for associated parts used.) b. Push the POWER key to turn the DAGR on, and make sure the DAGR [or DAGR system antenna] has a clear view of the sky. c. During power up, observe the power-on status display. Make sure that self-test passes and battery indication [batteries not applicable to system installation] shows sufficient battery power left. Do not use the DAGR if a failed self-test is indicated.

LP 0217 DAGR OPERATIONAL CHECKOUT Note –Push and Hold ENTER key (7) If Power-On Status remains displayed and does not time out, push the ENTER key to acknowledge. (8) The SV (Satellite Vehicle) Sky View page is displayed.

LP 0218 DAGR OPERATIONAL CHECKOUT e. With the SV Sky View page displayed, push the MENU key. f.Highlight Select Op Mode, then push the ENTER key. g. Highlight Continuous, then push the ENTER key. This mode enables the DAGR to acquire a current position fix. h. After satellites are acquired and a current position fix is obtained, the DAGR display stops blinking and Navigate SVs is shown on the SV Sky View page, then automatically switches to the Present Position page.

LP 0219 DAGR OPERATIONAL CHECKOUT Note –Display Blinks i,. Do the following before using the DAGR: Ensure the correct function set is being used Ensure the correct user profile is being used if using the advanced function set. Set the DAGR to the desired operating mode.
