Unpacking the Clock
1.1 Introduction
This section will assist you with unpacking the clock from its shipping container; other parts and
accessories shipped with the clock include:
• 1093A/B/C GPS Clock (includes internal power supply)
• 1092A/B/C GPS Clock (includes external power supply)
• Antenna Cable, 50 feet with connectors
• GPS Antenna
• Rack-Mount Ears, 2 ea. (1093A/B/C only)
• Instrument Manual
1.2 Precautions
Mechanical Shock Note that the GPS antenna is small and smooth, and can be damaged if
dropped. Use care when handling. Remember to store the antenna in a safe place before the final
installation.
Static Discharge Note that the Model 1092A/B/C and 1093A/B/C are electronic devices and
use static-sensitive components in their operation. Therefore, use care when handling against static
discharges. Generally, these components are protected in their normal situation, however some of
these are accessible when the cover is removed.
CAUTION Antenna Input Connector - Connect only the antenna cable coming from the
antenna into this connector. The antenna input connector on the clock itself leads to the GPS
receiver, which could be damaged from high voltage or a static discharge. To protect the GPS
clock from electrical discharges during operation, consider the optional surge suppressor (Part no.
AS0049000). For more information see Section 4.3.
