COLD START
When the AccuNav Sport™ is turned on for the first time
“out of the box”, it automatically sends a “cold start”
message to the GPS receiver. You can also send a cold
start message to the receiver at any time.

If the unit can’t lock on to the satellites using the data
you’ve given it, or if it has trouble finding the satellites,
perhaps it is using the wrong data. This can happen if
you’ve entered the wrong data by accident. For ex-
ample, giving it east longitude instead of west. Or if
you’ve moved a long distance with the unit turned off.
The unit will automatically issue a cold start to it's
internal GPS receiver, however, you can send a cold
start at any time.

To send a cold start message to the receiver, press the
MENU key. Now press the key next to the “CHANGE

GPS SETTINGS” label. Finally, press the key next to the
“GPS “COLD” START” label. The unit will begin a cold
start technique to find the available satellites. It should
lock on to them in 15 minutes or less. Remember, when
it does, your local time and possibly date display will
probably be wrong. Use the method shown previously to
set the time and date
to their proper local
settings. Once this is
done, an internal
clock will keep the
correct time, even
when the unit is turned
off. The GPS system
updates this clock
when the unit is
locked on to the sat-
ellites.
