4.7 Inserting the Batteries of the RCU
This is the procedure to insert new RCU batteries or to replace empty batteries:
Open the battery cover at the bottom of the RCU.
Insert two batteries 1.5 V (Type: AAA). Take care of the right polarity!

Replace batteries when the range of the remote control is de-
creasing or when the receiver no longer reacts to all commands.
When not used for prolonged periods of time, batteries may leak.
Remove batteries from the remote control if it is not used for long
periods of time (> 1.5 years).
When replacing batteries, always replace all batteries.
5Basic Operation
This chapter describes the necessary steps to use easily the radio and television programs
broadcasted via satellite.
5.1 Switching on Receiver
1. Switch on all connected devices.
2. Ensure that the correct AV input is selected at the TV set (i.e. that the signals from the
receiver are displayed).
3. Connect the mains plug to the power outlet to switch on the receiver
or
Switch on the receiver by using the power switch (on the rear panel of housing) (I, ON)4F

5.2 Software Update

Once you have put your receiver
into operation, you should first
update the operating software of your receiver!
5Depends on your receiver type.

Basic Operation
16
5.2.1 Update via USB
If you have Internet access, you should update your receiver via the USB interface.
1. Search for the upgrade file on the internet page www.avanit.tv (menu item Support).
2. If the version number of the update file matches with the version number of the software
of the receiver, which is displayed in the submenu Information of the menu Tools, you
do not need to do anything else. Your receiver is up to date. Otherwise continue with
step 3.
3. Save the update file to a USB data storage.
4. Unpack the file with the ending .abs.

Please note that the upgrade file (*.abs) is copied directly to the root
directory of the USB data storage (no subdirectory)!
5. Connect the data storage to your receiver.
6. In the menu Tools, select the sub-menu Upgrade by USB and press the OK key.
7. At Upgrade Mode, select the upgrade mode Allcode by using the keys und .
8. At Upgrade File, select the file copied in step 2.
9. Select the Start button and confirm by pressing OK.
A message saying that you will lose all personal settings will be displayed.
The upgrade will be performed after selecting
Yes by using the keys und and
pressing OK. Then, the receiver will automatically perform new start.
5.2.2 Software Update via Satellite
smart can also upload the update file on the satellite Astra 19.2° E. You can then perform a
so-called OTA5F
6update:
1. In the menu Tools, select the submenu OTA Upgrade.
2. Leave all settings unchanged (factory settings).

The option of software update via satellite is only possible via Astra
19.2°E. Correspondingly, all settings should be left unchanged in the
status as preset:

3. Mark the button Start by using the keys PR+ and PR-, and confirm by pressing the OK
key.
Now it is being checked if the software currently installed on the receiver is up-to-date. If
it is not up-to-date, then the current software version will be downloaded via satellite and
installed onto the receiver. After end of installation you will be asked if the update should
be saved.
4. Select the option
Yes to accept the update. The satellite update may take up to one
hour. Do not switch off the receiver during such period!
5.3 Commissioning
After first switching-on or after resetting the receivers, various windows will open:
5.4 Language
By default, the language is preset to Deutsch [German].
Please ensure that the setting is correct; you may
change your settings by correspondingly pressing
the keys PR+ and PR-.
Confirm by pressing OK to go to the next window.

The submenu Language can be
accessed anytime via the menu
System Setup .
5.4.1 RAPS Start
Your receiver is equipped with RAPS. RAPS means Receiver Automatic Programming Sys-
tem. RAPS can automatically update the channel lists of your receiver.
What is RAPS?
Currently, the satellites Astra 19.2° and 23.5°, Eutelsat Hot Bird 13° East, Eurobird 9° and
Turksat 42° offer a four-digit number of digital TV and radio channels.
At delivery, state-of-the-art satellite receivers have all important channels already stored. But
what happens after that? New and interesting channels are added almost weekly, and there
are channel changes time and again.
Updating the channel list with a present receiver is not quite easy for most users. When
performing a channel search, invalid data are not deleted, and usually the new channels are
just added at the end of the list; this requires time-consuming reprogramming of the channel
list.
The RAPS system of your receiver automatically performs such programming work.
The window RAPS Automatic Installation is the second window of the installation process.
Every time you switch off your receiver, RAPS checks whether there are any changes with
the channel lists (RAPS scan). This only takes a few seconds.
In case of changes, the new data are automatically included into the new channel list (RAPS
download) and displayed in a table. If a channel changes the receive parameters, then this is

Basic Operation
18
automatically updated by RAPS. In case of new channels, such channels are added. If chan-
nels are permanently discontinued, then the corresponding channel number is deleted.
However, new channels are not only added, but allocated to logic blocks, correspondingly
enabling easier finding. That is why certain areas may remain free. Example: For Germany,
there is the basic list as well as the areas Third Channels, Info + Sports, Special Interest,
Local TV, as well as News starting at channel number 100 and many Music Channels starting
at channel number 123.
You can cancel RAPS installation by press-
ing the key EXIT whilst the countdown of
RAPS installation is running (and also at a
later point in time during installation).
The then displayed channel list is a preprogrammed factory list. However, such list is not
updated via satellite due to cancelled RAPS installation!
The respective up-to-date RAPS lists are available via the satellite Astra 19.2°. Correspond-
ingly, RAPS can only be used within the footprint of the satellite Astra 19.2°; furthermore,
your system should be suitable for digital Astra receiving.

Press to go to the next window RAPS select raps file.
Examples:
•Your antenna system is designed for receiving Astra 19.2°E and Hotbird 13°E. These
satellites are found and marked in the list. You are planning to soon extend your antenna
system for receiving of Eurobird 9A 9°E. You can additionally mark Eurobird 9A 9°E al-
ready now to avoid repeated installation in the future.
•Your antenna system is designed for receiving Astra 19.2°E and Türksat 42°E. However,
the receiver in the children's room should only receive the German channels. For this,
manually deselect Türksat 42°E (found by RAPS-DiSEqC scan).
