ADJUSTMENTS

When the unit is powered for the first time, it is in a "cold start" state. There is no satellite data
(almanac data) stored. In this state, the unit searches for, and stores, satellites to find its heading.
This process takes approximately 90 seconds. If the heading is not found within 30 minutes, the
antenna installation location may not be suitable. A lack of visible satellites (less than four) can
also prevent the unit from finding a heading. Resolve the problem, then re-check the tracking sta-
tus.
If the heading error is between 5° and 10°, adjust the antenna unit orientation while monitoring the
heading indication.
At installation, when the unit is powered for the first time, some of menus required initial setting.
Initial settings can be done from the NMEA2000 network (TZTL2F/15F unit with software version
V6.0 or later is required), or from a PC (using the SC Setting Tool). For how to use the PC tool,
refer to the Operator's Manual for PC tools (SC_Setting_Tool: OME-72851). Once a heading has
been found, the following items may need setting or adjustment.
Also, when rebooting the SC-33, re-connecting of menu is required to operate from the TZTL12F/
15F (V6. and after).
