4. Select 57600 from the Baud rate drop-down list.
5. Tap ok to close the Setting window.
Operation
Acquiring satellite signals may take 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 microSD Card on page 1-4.
Answering a Phone Call While Using GPS
If you receive a phone call while using your GPS navigation software:
1. Answer the phone call by pressing the Answer button.
2. Once you end the phone call, press the End Call button to resume the audio on the GPS 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 strength, 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 satellites to
access information from the satellites.
Assisted GPS
GPS can be used in stand-alone or Assisted GPS (aGPS) modes. A Stand-alone GPS receiver downloads data
directly from GPS satellites. In challenging environments, such as urban canyons and areas where foliage is very
dense, aGPS can be used to improve Time To First Fix (TTTF). By default the MC65 uses the SUPL protocol which
requires the use of third party database/service from a carrier. By using GPS Location servers, A-GPS dramatically
improves the performance of the TTFF of GPS receivers by providing them with data that they would ordinarily
have to download from the GPS satellites. With the aGPS data, GPS receivers can operate faster and more
reliably.
Refer to the EMDK Help file for information on setting up SUPL on the MC65.
NOTE If an application error message appears indicating that the COM port cannot be opened, ensure that a free COM
port is selected in the
GPS hardware port drop-down list.
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 reacquire a valid GPS
signal, resulting in a a delay of positional information.
NOTE Anytime you are using GPS on the MC65 and you receive a phone call, the audio on the GPS navigation software
is muted until you finish the call.
