1.2 Turning On and Off the

The GP-80 takes about two minutes to find
position when turned on for the very first time.
Thereafter it takes about 20 seconds to find
position each time the power is turned on.

The unit tests the PROGRAM MEMORY,
SRAM and battery for proper operation and
shows the results on the display. If equipped
with the internal beacon receiver, "BEACON

used display mode.
