Garmin gpsmap 162 Manuale Utente

21

The following options are available:

•    Start/Stop Simulator— allows you put the unit in simulator mode. See the Getting Started Tour 

for more on using simulator mode.

•    Enable/Disable WAAS— allows you to activate or deactivate WAAS. ‘WAAS’ is an acronym for 

“Wide Area Augmentation System’. You can use the WAAS capability to increase the accuracy of 
the GPSMAP 162. When enabled, the GPS receiver searches for a WAAS satellite, then receives 
data that will help correct differentials in the GPS signal. When the unit is using WAAS data, 
“WAAS” will be displayed  in the ‘DGPS Rcvr’ fi eld on the Status Page, and the receiver status 
will indicate a 2D or 3D Differential Location.

     Currently, the WAAS system is not fully operational and there are only two satellites in 

place—one over the Pacifi c Ocean and one over the Atlantic Ocean. You must have a clear, 
unobstructed view of the sky for the GPSMAP 162 to be able to receive a WAAS signal. Even 
then, at times it may not be possible to receive a WAAS signal. For more information on the 
WAAS system, visit the Federal Aviation Administration web site at (gps.faa.gov).

•    Track Up/North Up— allows you to select between a north up or track up sky view display 

for the Status Page only.

•    Loran TD On/Off— allows you to toggle the position coordinate format between latitude/

longitude and Loran TD (Time Delays). For setup of Loran TD, see pages 72-73.

•    AutoLocate— allows the receiver to locate your position automatically. This process can take 

up to fi ve minutes.

•    Initialize Position— allows you to initialize the receiver graphically on the Map Page to initially 

help the receiver acquire more quickly. See pages 4-5 for instructions on initialization.

•    Set 2D Altitude— allows you to manually enter the altitude when in 2D Navigation or 

Simulator mode only. Any altitude entered will be automatically calculated when the GPS is
