The GP-1A does not supply the compass heading.  Local geographic and atmospheric conditions 
may prevent or delay the acquisition of GPS data. The GP-1A may be unable to receive GPS data in-
doors, underground, or in the vicinity of large structures, trees, or other objects that block or refl ect 
satellite signals.  The positions of GPS satellites are continuously changing, preventing or delaying 
the acquisition of GPS data at certain hours of the day. The presence of cellular telephones or other 
devices that transmit on frequencies close to those of GPS satellites may also interfere with the ac-
quisition of GPS data.
Note that the GP-1A may take several minutes to reacquire a signal if the unit has not been used for 
an extended period or has been moved a great distance since GPS data were last received.
