CONFIGURATION
Æ TX-PARAMETERS Æ SLOPE
TX SLOPE: MODE=MANUAL (MANUAL,CAL)
SLOPE=0.3 (0.0 - 1.0)
Select MANUAL or CALIBRATED using the [
↑][↓] arrow keys. If Manual mode
is selected, the slope may be edited. Select the digit to edit using the [
←][→] arrow
keys, then use the [
↑][↓] arrow keys to modify that digit. Press [ENT] when done, or
[CLR] to cancel the edit and return to the previous menu.
CONFIGURATION
Æ RX-PARAMETERS
RX: FREQ=3600.0 MHz ATT=18.00 dB
MUTE=UNMUTED SLOPE
Select the parameter to edit – FREQ, ATT, AMP, MUTE, or SLOPE – using the
[
←][→] arrow keys, then use the [↑][↓] arrow keys to modify that parameter setting.
Press [ENT] when done. Observe the following:
FREQ
(Frequency) Edit the Rx frequency by first selecting the digit to be edited using
the [
←][→] arrow keys, then changing the value of that digit using the [↑][↓]
arrow keys. Press [ENT] when done or [CLR] to cancel the edit and return to
the previous menu.
ATT
(Attenuation) Edit the Rx attentuation by first selecting the digit to be edited
using the [

Select MANUAL or CALIBRATED using the [
↑][↓] arrow keys. If Manual mode
is selected, the slope may be edited. Select the digit to edit using the [
←][→] arrow
keys, then use the [
↑][↓] arrow keys to modify that digit. Press [ENT] when done, or
[CLR] to cancel the edit and return to the previous menu.
