4.6. Range Button
When the MAP is enabled, the RNG (Range) button is used to zoom in or out in scale to
display more or less of the map. The map range available depends on the VIEW. Press
the top or (+) of the RNG key to increase map range. Press the bottom or (–) of the RNG
key to decrease map range. Additionally an Auto Range feature is available.
Pressing and holding either the (+) or (-) of the RNG key will cause the map range to
scale continuously to its maximum or minimum range, respectively. When the map
range is at its maximum or minimum setting, pressing and holding the RNG key again
will activate Auto Range mode (see Section 5.1.3. for completedetails).
4.7. Cleaning the Display Screen
The EFD1000/500 MFD display is an LCD screen that is prone to damage from scratches,
smudging, and clouding caused by the use of improper cleaning agents and harsh
cloths. Use care when cleaning, using the following tips:
• Only clean the display when the unit is o.
• Use a clean, soft, lint free cloth dampened with a 50/50 solution of isopropyl
alcohol and water, a pre-moistened lens cleaning tissue like Bausch & Lomb Sight
Savers®, or a cleaning solution made especially for LCD displays.
• Never spray any cleaning solutions directly onto the screen, spray it into the
cleaning cloth.
• Gently wipe the screen in a circular motion. Do not press hard on the cloth.
• Remove all excess moisture to prevent damage of the EFD1000/500 MFD display.
• The EFD1000/500 MFD display should be dry before powering the unit on.
NOTE
Use caution when using isopropyl alcohol as it is
ammable. Using any other chemicals or materials
voids the warranty.
