1.2 How to Turn Power On/Off
1. Press the /BRILL key to turn on the power. The unit beeps and then starts up
with the last-used display mode. Your equipment takes about 90 seconds to find
its position. The equipment shows receiver status indication at the top left-hand
corner in most display modes. The table below shows these indications and their
meanings.
Status indications
*: DOP (Dilution of Precision) is the index of position accuracy, and it is the distri-
bution pattern of satellites used in position fixing. Generally, the smaller the figure
the better the position accuracy. (HDOP: Horizontal DOP, PDOP: Position DOP)
2. To turn off the power, press and hold down the /BRILL key for three seconds.
The time remaining until the power is turned off is counted down on the display.
