The settings of items 3-9 automatically change according to selection made at step 4. Press the [MENU] key. -1. 32- 1. 34. 2 Activating/deactivating a function Press the [FUNCTION] key. Each time the key is pressed a preset function the preset functions enabled on the FUNC menu are turned on or off cyclically. You may enable/disable preset functions from the menu as follows: 1. Press the [MENU] key followed by the [6] key twice to display the FUNC menu. 0.

Press the [MENU] key followed by the [5] key twice to show the ECHO SIG menu. Press the [4] key to select OFF or ON from the ENHANCE field as appropriate. Press the [ENTER/SELECT] key, and then press the [MENU] key. Echo enlarged in bearing and range directions 1. 37 Watch Timer The watch timer works like an alarm clock, sounding visual WATCH and audible alarms at a predetermined interval. To silence the alarm, press the [AUDIO OFF] key. The label WATCH turns to normal color and the alarm timer is reset to the initial and starts the count-down sequence again. Press the [MENU] key followed by the [4] key twice to select WATCH TIME. WATCH TIME 1. ALM INTVL OFF 3min 6min 15min 20min 12min 2.

Press the [7] key to turn the noise rejector on or off as appropriate. [. . . ] The positioning system Mode indicator and Status fields shall not be null fields. -8. 5- HDG - Heading, deviation and variation IMO Resolution A. 382 (X). Heading (magnetic sensor reading), which if corrected for deviation, will produce magnetic heading, which if offset by variation will provide true heading. $--HDG, x. x, x. x, a, x. x, a*hh<CR><LF> Checksum Magnetic variation, degrees, E/W (see notes 2 and 3) Magnetic deviation, degrees, E/W (see notes 1 and 3) Magnetic sensor heading, degrees * Not used NOTES 1 To obtain magnetic heading:Add easterly deviation (E) to magnetic sensor reading Subtract westerly deviation (W) from magnetic sensor reading 2 To obtain true heading: Add easterly variation (E) to magnetic heading Subtract westerly variation (W) from magnetic heading 3 Variation and deviation fields will be null fields if unknown.
