Introduction

This quick reference guide is intended for individuals who are responsible 
for installing the QPSK D9494 Demodulator into a rack unit.
For more detailed descriptions of the installation process and safety 
information for this demodulator, refer to the

Controlling the Operating Temperature

 CAUTION: The operating temperature for this equipment is 

32 to 122°F (0 to 50°C). Avoid damage to this product! Your warranty 
is void if you operate this product above or below the maximum 
speci

fi

 ed operating temperatures.

Measuring the Inlet Air Temperature

If you are concerned about inlet air temperature at the air inlet of any 
demodulator, you can measure the inlet air temperature in the rack. When 
measuring the temperature, ensure that all cabling is complete and that 
all adjacent QPSK demodulators are installed and running.

Important:

 Opening the door on the back panel of the rack may have an 

adverse effect on the managed air

fl

 ow. If access to the door is not controlled, 

measure the inlet air temperature with the back panel door open because 
this typically redirects the air

fl

 ow in an adverse manner.
