Page 5: Warnings And Cautions
Warnings and Cautions Caution: Use this radar at your own risk. This radar was designed for use as a navigation aid. It should not be used for purposes that require precise measurements of direction, distance, topography or location. Always compare the navigation information received from your radar with data from other navigation aids and sources. - Page 6 WARNING: Microwave Radiation Hazard The microwave energy radiated by a radar antenna is harmful to humans, especially to the eyes. NEVER look directly into an open waveguide or into the path of ra- diation from an enclosed antenna. Radar and other ra- dio frequency radiation can upset cardiac pacemakers.

Page 7: Section 1: Introduction
Section 1: Introduction Thank you for buying a Lowrance Radar with the RIM 100 radar inter- face module. Your radar consists of three main components: the radar scanner unit (antenna), your display unit (sold separately) and the RIM 100 radar interface module which connects the scanner and display units. WARNING: Radar radiation can be harmful to you and bystanders. -
Page 8: Update Display Unit Software
This manual covers the following radar units: LRA-1000, LRA-1500, LRA-2000 radomes; and LRA-4000, LRA-5000 open array radars. Update Display Unit Software Your display unit must have software version 1.3.0 or later to work with radar. Depending on when you bought your display, it may require a software update. - Page 9 When the echo returns, it is processed by a computer to determine rela- tive distance, position and bearing of the object that reflected the sig- nal. This information is displayed on the display unit's screen. Other boats or ships, navigational markers, landmasses and the like are re- ferred to as targets.

Appendix I: Glossary Anti-Rain Clutter (FTC): used to reduce or eliminate massive num- ber of small echoes that clutter the display during rain or snow storms. Anti-Sea Clutter (STC): lowers receiver sensitivity at shorter ranges to reduce or eliminate sea clutter echoes, which are most prevalent around the vessel. - Page 54 Heading Line Adjustment: the Heading Line is used to make sure the green heading line (zero point) on your radar display is lined up the bow of your vessel. Heading Up: when your heading is displayed at the top of the screen, you are in Heading Up mode.
- Page 55 Transmit Off Zone: an area set up in the radar transmission path where the radar will not transmit a microwave pulse. Tuning: intermediate frequency adjustment that enhances the per- formance of the radar. VRM (Variable Range Marker): a range ring used to measure the precise distance to a target, the variable range marker may be adjusted to measure any distance within the radar's range.
