If you do a search on rcu tanks you will discover the radio you purchased is not recommended for Tamiya rc tanks. Like the above Tamiya printed notice says, the radio you purchased is best used with Tamiya rc big rig trucks.

You will not be happy with the function delay as you try to access various effects like cannon fire etc. If your OK with a poorly functioning Leo 2, well no harm then.

Why not take the radio back to the store, this is not new news, and tell them they sold you the wrong radio for your kit. Print out the Tamiya notice above and take it with you, if you do not have the blue notice sheet that came with your Leopard 2 kit. Do not give up that easy.
