Specifications

GPSPC 2/17/2003 4 Masterclock, Inc.
Although changing the GPS antenna or coaxial cable is not technically difficult, you are on your own should
you decide to make such changes. We do not warrant or support operation with any hardware not installed
or supplied by us.
ANTENNA COAXIAL CABLE
The coaxial cable should not be crushed, crimped or bent at a sharp angle nor should it be strained by pulling.
Any damage to the cable could result in the GPSPC not functioning properly. If the cable is to be coiled for
storage, the coil diameter should be at least 6”.
PROBLEMS - TROUBLE SHOOTING
All GPSPC units are checked for proper operation before shipment. Unless physical damage is found, the unit
has been proven to be functional at the factory.
Please remember for an initial startup at a new location the unit could take up to 30 minutes. After the unit has
acquired satellites at the new location, the startup time is greatly reduced to anywhere from a few seconds to
several minutes.
If the antenna (and coaxial cable) has not been damaged and has an unobstructed view of the sky, the power
connector is properly installed and the front panel LED follows the startup sequence described earlier (on, off
& then on), the unit is working.
If you continue to have problems even after the above precautions have been noted please contact the
factory.
