[ANALOG CHECK]
This screen is to check the analog circuit of the transceiver unit. For example, if you
set 10 kn as ship’s speed for test, check that 10 kn is displayed in the [RESULT]. If
there is a discrepancy between this set value and the result, there may be a malfunc-
tion so contact your local dealer.
During displaying the [ANALOG CHECK] display, the ship’s speed is not calculated.
To go to the [MAINTENANCE] window, press the MENU/ESC key.
• [CHECK SPEED]: Set the ship’s speed for test to check the analog circuit. The set-
ting range is [-10.00] to [40.00] kn (default: [10.00] kn).
• [SPEED]: Show the ship’s speed/direction which the transceiver unit outputs. This
value is updated every second. The setting range is [↓ 99.99] to [↑ 99.99] kn. Ship
direction is indicated as follows: [↑] means “Go forward” and [↓] means “Go back-
ward”.
