Reducing Tx output signal power

Hi,

I have bought this RTF indoor heli:
http://www.amazon.co.uk/Merlin-Trace.../dp/B0039JCFU2
a 2.4 Ghz Tx is included. Regulations at my country state that the signal power output should not exceed 10 mW. After asking a friend with some experience in RC stuff, he said that most probably all transimetters exceed 10 mW. How can I reduce the signal power of my transimtter? Is there an RF amplifier that can be deactivated or temporarily removed from Tx to guarantee reducing the power below 10mW? Is there more simple & easy ways to do this?
Any advice/help is appreciated.

10mW limit is for continuous (analog) transmission, and is valid worldwide.
RC is digital, and don't transmit permanently, but pulsed, and is safe.
Is regulated same way as the wireless routers, which are legal in your country, I guess .

"RC is digital, and don't transmit permanently, but pulsed, and is safe."

Not quite true. The "data train" is digital, but the carrier that carries the data is analog, and continuous.

Les, 2.4 GHz is not a continuous carrier. It is pulsed.
