General Safety Precautions

To Prevent Overheating
The recom mended clearences and other precautions given in this instruction section of these
instructions must be observ ed to prevent overheating. In addition, the units should not be fixed where
they are likely to become smothered by curtains or other fabrics, etc, or other the rmal inssullation
materials in a roof space or sim ilar buildin g void. The unit should not be left resting on a carpe t.
Other Precautions
These appli ances are not waterpro of. The y are for indoor use onl y and must no t be fixed where they
could be exposed to drippin g or splashing water. Ob jects containg liquids should not be placed on or
near the appliance.
To preve nt risk of fire, no objec t with a naked f lame should be plac ed on or near the applianc es or the
wiring to them.
Fitted Mains Plug
These appliances are supplied with a standard fixed plug already fitted. If this is not suitable, refer to the
instructioo ns below. In the unlikely event that you need to change the fuse in this plug, 1 3Am p fuse to
BS1362 ca rrying th e ASTA or BSI approved mark must be used. Alw ays re-fit the plastic fuse ca rrier when
replaci ng the fuse.
Changing th e Plug
If the fitted mains plug is no t suitable for the socke t outlet in use, it should be cu t off and an appropr iate
new plug fitted.
Wiring a New Plug
Any ins truction supplied wit h the plug should be followed(th ese may state how m uch insullation to
remove from the wires in the mains cord). The Bro wn wire must be co nnected to the live (L) terminal of
the plug and the Blue wire to the neutral (N) terminal. Neither wire should be connected to the earth (E)
terminal of a 3-pin plug(this appliance does not require an earth connection). Ensure that the cord g rip
in the plug is correctly used and clamps the sheath of the cord firmly.
Fuse Rating: If the new plug is a fused type, the fuse fitted should be rated at no more than 3 Amp.
Caut ion : The old plug sh ould be d estroyed promp tly since it would b e dangerous if plugged i nto the live
socket.

Introduction
These ful ly screened gene ral-purpo se 4, 6 and 8 wa y amplifiers are ideal for distributing TV and
FM DAB radio signals. Separat e inputs for UHF TV (470- 862 MHz)a nd for FM DAB. The FM DAB
operating for the standard unit UK market is 88-230 MHz. Versio ns are also availabe with VHF
frequency range 40-270 MHz– specify by a dding suff ix EIR to the product code.
The 6 and 8 –w ay versio ns feature a higher gain "FULL" out put. This may be used in conjuct ion
with additional passive accessories(taps and splitters) to allow additional outputs to be fed.
All units are suitable for handling digital terrestrial TV (DTT) signa ls in addition to the analogue
services. Dis tribution of DTT sign als requires c areful attention to signal levels for satisfactory
results.
Applicatio ns
Using the "FULL" ouput
The "FULL" output allows additional points to be fed without the need for another amplifier.
The diagrams below and overleaf show two typical examples of how Labgear ta ps can be used
to provide ano ther 8 or 16 out puts. NB the taps in these examples have f-type connectors.
