If you are experience reception problems after 
installing the SLx, please see below:

No picture or sound

No signal is reaching your television due to a 

possible break in the aerial signal path. Ensure that 

all equipment has been switched on (including the 

SLxG amplifier) and that all coaxial connectors have 

been fitted correctly.

Problems with Digital TV Recepion

Unlike analogue terrestrial television, it is not 

possible to view DTT channel under weak signal 

strength conditions. Therefore, typically you will 

either receive DTT channels with a clear picture and 

sound or you will not receive any channels at all.
A weak digital signal can cause occasional blocking, 

freezing or complete loss of picture. Ensure that your 

aerial is a wideband, high gain aerial suitable for 
DTT reception. Blocking, freezing or complete loss of 
picture can also occur when the signal is too strong.

If the signal is still too strong, fit a signal attenuator 
between the aerial downlead and DTT receiver to 
reduce the signal strength.

Problems with satellite television

If you are experiencing any problems with your 
satellite television picture, check that all cables 
and connectors have been fitted correctly. If the 
problem persists it is probably due to the dish 
alignment or a temporary problem with the channel 
transmissions. Please contact your local satellite 
dealer if the problem persists.

Green LED configuration

Green LED - Power on

Amber LED - Surge and Spike Protection

When the amber light comes on the SLx logo back 
light will go out. This indicates that there has been a 
power surge or spike, this will return to normal and 
will require no action by yourself. After the power 
surge or spike has passed the amber light will go 
out and the SLx gold logo will be lit again. This 
feature ensures that you have that extra protection 
and piece of mind. 

Red LED -Short Circuit Protection

If the red LED comes on remove the output coaxial 
cables one by one until the red LED goes out. 
Replace leads one by one, if the red LED light comes 
on, there is a short circuit between the central 
conductor and the braiding on this coaxial cable. 
Check the wiring of the connectors/connections on 
both ends of the cable to see if there is a strand of 
braid touching the central conductor. If so, rewire 
the connection so that the braid is well clear of the 
central conductor and retry procedure.
