8.7 Cooling Fan Maintenance

The MDS 4790/9790 Series uses cooling fans to cool the main trans-
ceiver boards. To ensure that the fans operate correctly, inspect them on
a regular basis and keep them clear of dust

9.0 RADIO SOFTWARE UPGRADES

From time-to-time, GE MDS releases new software code for its radio
products. You can download this code into existing radios to take advan-
tage of engineering improvements, or to change the operation of a radio
with a new modulation type.
For example, an MDS 4790B which is compatible with the MDS
4100/4310 family can be changed to an MDS 4790A to be compatible
with the newer generation of DSP-based radios by changing the soft-
ware and authorization code. Contact GE MDS Technical Support for
modem change information. If a radio is changed to a new modulation
type, you should also obtain a new Installation/Operation Guide from
GE MDS that contains the appropriate command descriptions.
