Mode 3
When the RFI-9256 is in Mode 3 the display changes to an LED bar graph display that indicates the
Transmitted RF power. The display has a resolution of 3dBm steps from a maximum output power of
+30dBm or 1Watt using the RED LEDs. Table 5-3, below, show the relationship between the LEDs and
the indicated output power (included on the front panel) under the heading Mode 3. This display is used as
an indicator to show the current level of the transmitted RF power.
To meet Spread Spectrum Standards, the total power rating leaving the antenna is not allowed to radiate
more than 1 Watt. The power settings, in the software, allow the user to adjust the power level to maintain
the maximum possible EIRP. For example, if the user wishes to use a gain antenna, he/she must set the
power level in the modem so the total power radiated by the antenna does not exceed the EIRP.

Mode 4
When the RFI-9256 is in Mode 4 the display changes to a LED bar graph display that indicates the
Temperature of the RFI-9256 Radio. The temperature is displayed using green LEDs for steps of 10°C
from 10° to 60°C. Table 5-4 below shows the radio temperature according to the LEDs on the front panel.
When the unit is operating within the green area the radio is operating inside its operating window.
Temperatures above 65°C are displayed as a full red bar. Temperatures below 5° are displayed as a
single red LED. These are both fault conditions.
