module is shown below:
5.1. Normal menu
a. Input menu
The fi rst main menu allows you to select for the
input signal: the frequency or channel, the off set
( channel mode only), the bandwidth and the
preamplifi ers powering.
To make a change press the key

by means of the keys and .
You can select any output frequency value between
177,5 - 226,5 MHz (VHF) and 474-858 MHz (UHF).
The decimal part depends on the frequency step
selected (see extended menu b ). If the frequency
step is defi ned as 125KHz, decimal part values
allowed are: 0, 125, 250, 375, 500, 625, 750 and 875
KHz. If it is a 166 KHz step, then the values allowed
are: 0, 166, 333, 500, 666 and 833 KHz.
Possible COFDM Bandwidths are: 7MHz or 8MHz.
Available voltages to power preamplifi ers are: 0, 12
and 24 Vdc
In the case of a shortcircuiting condition in the
input connector (line power set to ON) the frontal
LED will be blinking until it is fi xed.
b. Output menu
The next main menu shows the frequency or
output channel, the output off set (only in channel
mode), the level control and the selection of
output mode.
