Dealer calibration also gives access to the Factory defaults screen. This enables
you to re-apply the factory settings if you want to reset the instrument to a known
operating condition.
To commence Dealer calibration, hold down the disp and true/app keys
together for approximately 12 seconds, to select the Dealer calibration entry page
(see Dealer calibration diagram, sheets 1 and 2). Then momentarily press the
vmg
and tack keys to proceed with the calibration. As the calibration progresses,
use the disp key to move from screen to screen.
User calibration on/off
Use either the vmg or tack key to toggle the User calibration either on (UC1) or
off (UC0) as required.
Response settings
The response values (for wind speed, wind angle and VMG) determine the
frequency at which information is updated. A low number provides a smooth
response and a high number a much livelier response with rapid pointer
movement.
Use the vmg (decrement) and tack (increment) keys to set the required value.
Response values are from 1 to 15 .
Wind speed
The Wind speed and Wind speed calibration screens are used to set the correct
value for the wind speed. On entry (from the Wind speed response screen), the
current value for apparent wind speed is displayed. Set the correct wind speed
value, by applying a calibration factor as follows:
1. Use the vmg (decrement) and tack (increment) keys to switch from the Wind
Speed screen to the Wind Speed Calibration screen.
2. Use the vmg (decrement) or tack (increment) key to set the wind speed cali-
bration factor to 0.7.
3. Timeout to the Wind Speed screen, and if further adjustment is necessary,
repeat steps 1 and 2.
