The CEM70 mount is equipped with a GPS receiver which will receive the UTC time, longitude and
latitude information for your current location from satellites after a link is established. However, there are still
some parameters need to be entered to reflect your location, such as time zone information and whether
daylight saving time is currently in effect. This information will be stored in the mount until they need be
updated.
The GPS should make the mount to connect the satellites in a few minutes. If the GPS module has
difficulty receiving the satellite signal, you may manually enter the information.
