1. LOCATION OF THE RECEIVER

2. CONNECTING THE RECEIVER WITH AERIALS

CONNECTING YOUR “DTB-9401F”

Your DTB-9401F should be placed under proper ventilation.
Don’t put in completely enclosed cabinet that will restrict the flow of air,
resulting in overheating.
The location should be safeguarded from direct sunlight, excess moisture,
rough handling or household pets.
Avoid stacking other electronic components on the top of the receiver.
The location should be safely accessible by the cable from your antenna system.

You can connect the receiver to the following type of aerials:
" Use a standard outdoor roof aerial intended for receiving channels between

VHF and UHF.

" Because many older roof-mounted aerials may only receive a limited number

of channels, it is difficult or impossible to receive digital channels transmitted
on higher frequencies. If so, you may replace the roof aerial.

" Some outdoor aerials are directed towards an analogue transmitter.

The aerial must be directed towards a digital TV transmitter.

" It is not desirable to use indoor or window mounted aerials,

as it will be difficult or impossible to receive digital channels.

3. CONNECTING THE RECEIVER TO TV

To connect the receiver with your television, you can use Scart Cable.
In the case of connecting your TV through SCART cable,
connect the SCART connector marked TV to the respective SCART port on the TV.

4. CONNECTING YOUR VCR

To connect a VCR, the DTB-9401F has been provided with SCART
at the rear marked “AV2(EXT)”.
Using a SCART connector, the VCR can be connected to the receiver.
