Ensure that the unit is connected to a suitable power source. The power adapter for this
equipment has an input of 220 V and an output of 12 V DC. If the STATUS LED is still off, the
unit is likely to be faulty and should be returned to Ascent Communication Technology for
repair.

The optical level entering the unit is too low or too high and must be adjusted externally to
the unit, for optimal performance.
If the optical level entering the unit is too high, it could cause permanent damage to the unit.
The signal should be disconnected and attenuated to an appropriate level, before
reconnection to the AON126S. If the unit does not function as specified it is possible that the
unit has been damaged and should be returned to Ascent Communication Technology for
repair.
No RF output
Ensure that a forward-path signal is present on the system, at the correct wavelength for the
AON126S to receive. If the signal is present, but not at the desired level, adjust the RF ATT
control.
Keep the optical connector clean, a poor link will reduce the RF output level.
