In Manual Mode the RF attenuation is controlled by dip switches (SW1-SW5). Each toggle switch
changes the Input RF attenuation level by 1,2,4,8 and 16dB respectively. Toggling the position on any
switch is the sum of the attenuated amount
ie switch 1 (16dB) and 3 (4dB) enabled will provide an
attenuation of 20dB.
See Table 4 for switch control Note: On is up position, down is off.
