Introduction
This section introduces the Model 1095A/C Industrial GPS Clock and
covers unpacking the Model 1095A/C, identifying components and
accessories.
The Model 1095A/C may be ordered in four different configurations.
• Model 1095A with internal antenna (see Section 1.4.1)
• Model 1095C with internal antenna (see Section 1.4.2)
• Model 1095A with external antenna (see Section 1.4.3)
• Model 1095C with external antenna (see Section 1.4.4)
The following information will assist you with identifying components
and accessories for each of the four configurations.
1.1 Unpacking
While the clock is housed in a rugged case intended for outdoor use,
handle carefully, especially during setup while the cover is removed.
Some of the components are sensitive to shock and static electricity.
After opening the shipping container, you will find four M4 screws
securing the cover to the case. For access to wiring and programming,
you will need to remove these screws.
