Ariva 153 slow switching on

Hi,
I got Ariva 153 Combo and was surprised by it's slow switching on by remote control (not backside power switch). It's taking around 15 seconds to show startup channel. The same problem is for original and emu firmware (V1.29B8).
I've compared it to my old Ariva 150 Combo, which switching on just in 3 seconds (from standby to startup channel). :thum:

Is it normal behavior or able to fix for Ariva 153?

Thanks for answer!
But, if it is not possible to reduce this time to switch on, is there other Ariva Combo with fast switching on (stays connected to the network during standby) like ariva 150? Or all current Combo's disconnecting from the network?
