Atari 2600 clone - 510 games built-in

This is an Atari 2600 clone with 510 games built-in. It origins from Taiwan; the manufacturer is a company named: "RINCO". Anyone heard of that?
The bottom of the case reads:

RINCO (both stamped into the plastic and one adhesive label)

MADE IN TAIWAN

And here comes a very strange thing, which really makes me think: on the back left side of the console is a white label with some hand-writing on it:

And yes, this is arabian. I will give a translation as soon as possible...can anyone read this?
What does a sticker with arabian writings on it do on a game-console manufactured in south-east asia and discovered on a german flea-market?

This console is built into a 2600A case with some differences:

1) The "b/w"-switch was replaced by the "game select"-switch.
2) The "game select"-switch was replaced by the "game player"-switch.
3) The case isn't as heavy as the original Atari one (cheaper plastic).
4) Just beside the power-plug on the back left of the machine there is the most important switch: the "game group switch".
Apparently this switch is used to select the different game banks that contain the 510 built-in games.
5) On the back right side of the console there is a hole with the same size of the hole where the "game group switch" resides in. It is covered with black adhesive tape.
6) There is no channel-selector switch.
