8 - 2 MC65 User Guide

Operation
Acquiring satellite signals may take several seconds to a few minutes. It is best to be outside and have a clear,
unobstructed view of the sky. Without a clear view, acquisition takes much longer and could result in the MC65
being unable to compute the initial position quickly. When operating the device indoors access to the GPS signals
may be limited or unavailable.

GPS Maps on microSD Cards

GPS navigation software vendors may sell maps on microSD cards. If using a microSD card with the GPS
navigation software install the microSD memory card using procedure in Installing a mic roSD Card on page 1-2.

Answering a Phone Call While Using GPS

If receiving an incoming phone call while using your GPS navigation so ftware:
1. Answer the phone call by pressing the Answer button.
2. Once the phone call ends, press the End Call button to resume the audio on the GP S software.

Losing the GPS Signal While in a Vehicle

GPS performance on the MC65 may be affected if the vehicle has thermal glass windows and windshields, which
can block the MC65 from receiving a GPS signal from satellites. To improve GPS signal stren gth, place the MC65
where there is a clear view of the sky. A direct line of sight is required between the MC65 and the GPS satelli tes to
access information from the satellites.
Assisted GPS
GPS can be used in stand-alone or Assisted GPS (A-GPS) modes. A Stand-alone GPS receiver downl oads data
from GPS satellites. In certain environments, it can take several minutes to get a fix. B y using GPS Location
servers, A-GPS dramatically reduces the TTFF (Time T o First Fix) and improves the se nsitivity of GP S receivers by
providing them with data that they would ordinarily have to download from the GPS sat ellites. With the A-GPS data,
GPS receivers can operate faster and more reliably.
The GPS Assist application provides the ability to modify the settings ass ociated with obtaining GPS data.
Tap Start > Settings > Connections > GPS Assist.
NOTE When using a GPS navigation application, ensure that the MC65 does not go into suspend mode. If the MC65
suspends then the power to the GPS radio is removed. Upon resume the GPS receiver must reacqui re a valid GPS
signal, resulting in a a delay of positional information.
NOTE Anytime using GPS on the MC65 and you receive a phone call, the au dio on the G PS navi gation sof tware is m uted
until you finish the call.
