Before starting the EPSILON CLOCK®, perform the following tasks:
•
Position the machine so that the upper and lower air vents are not obstructed.
•
Position the GPS antenna outside with an unobstructed view of the sky over 360
degrees (on top of a mast, for example).
CAUTION:
The EPSILON CLOCK® is designed to be used with the
supplied GPS antenna ONLY. Using another antenna
may cause significant damage to the unit and will void
your Spectracom warranty.
•
Plug the antenna cable into the TNC “Antenna” connector. To ensure the correct
reception of the GPS signal, the overall system of antenna/cable/protection requires a
gain between 15 and 30 dB, with optimum reception around 24 dB.
