Section 2: Unpacking and positioning
To install an XR12 transmitter, perform the following tasks:
1. Lift and slide the transmitter cabinet off the base of its crate.
2. If necessary, remove the power modules from the transmitter.
Without the power transformer, and with the power modules installed, the XR12 transmitter
weighs about 197.77 kg (436 lbs)
• Remove both of the transmitter’s rear covers.
• Remove the packing bolt at the rear of each RF power module.
See
Figure 2.2 on page 2-3 .
• Remove the connector under the front of each RF power module. See Figure 2.1 on page
2-2 .
• Remove both top mounting screws, and the bottom mounting screw behind the
connector, on the front of each RF power module. See
Figure 2.1 .
• Grasp an RF power module’s handle and pull the module out through the front of the
transmitter. Remove other RF power modules the same way.
Note:
As the RF power module slides out, there is a cutout in the top of the module’s
rear panel that can serve as a hand hold. See Figure 2.1 .
• Store the RF power modules in a location where they will be safe from mechanical
impact, dirt, dust, cold, heat, or weather, until you are ready to reinstall them.
CAUTION: An RF power module weighs approximately 20 kg (42 lbs.). Use care
when lifting the module.
