5.5. Question: What are the correct specifications for a GSM SIM
card in order for it to operate with the G3100?
Answer: There are three key items that must be specified to get
the correct GSM SIM card and service from your cellular service
provider;
GSM SIM card (not UMTS)
Data service only
No IMEI number (i.e. no associated hardware/handset)
SIM cards that had one or more of the above 3 features
incorrect did not work. In the USA, AT&T and T-Mobile provide
GSM SIM cards that have been used successfully with the G3100.
5.6. Question: Why am I not receiving GLONASS corrections?
Answer: You must first verify that the base station transmits
GLONASS corrections. The G3100 first utilizes GPS satellites to get
to RTK Fixed status. Then if more than 2 acceptable GLONASS
satellites are available, RTK Fixed GPS+GLO RTK status is
achieved.
5.7. Question: Why is my radio not receiving RTK corrections?
Answer: Check Base Station Configuration. Make sure that Base
Station receiver is set up and using more than 5 common
Satellites. Check Rover Configuration; make sure that it is
configured to use the correct RTK format corrections. Both Base
Station and Rover must use the same UHF Radio Channel and
same correction format.
5.8. Question: How do I know which message type to select RTCM
V2.3, RTCM V3.0, CMR, or CMR+?
Answer: Base stations transmit different messages types. It is
important to confirm what message type(s) the base is
transmitting so the Rover can be set accordingly.
5.9. Question: How can I verify the Windows Mobile® version my
hand held device is operating on?
Answer: In the main view of the controller, select the Start Menu,
next click Settings Menu, then select the System tab, lastly select
the About icon which will display the Windows Mobile® version.
5.10. Question: I can’t connect to the G3100 via Bluetooth®, why not?
