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:
• 1084A/B/C GPS Clock (includes internal power supply)
• Antenna Cable, 50 feet with connectors
• GPS Antenna
• Rack-Mount Ears, 2 ea.
• 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 1084A/B/C series clocks 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.
1.3 Unpacking and Locating Accessories
The Model 1084A/B/C series clocks, and included accessories, are packed between two closed-cell
foam shells. Carefully pull apart the two shells to extract the clock and accessories. Some of the
accessories (i.e. antenna and rack-mount ears) are located in one of these shells for protection.
In the diagram below, you can see how the GPS antenna and rack-mount ears are located in the
closed-cell foam marked with the label that reads,
