I love my Aiwa but lost the remote . I have now found it but cannot get my Aiwa to work. When plugged in it shows the red standby button but will not do anything at all. I am gutted as this is a fantastic Hi fi and desperatley want it repaired. Anyone help please

i have always bought aiwa because it's the best make to me anyway. i was wondering where i could get a user manuel from? can you help please ? many thanks
