2 ap belong different regulatory domain  , and I've done setting up the channel fixed as I expected

AIR-CAP2602I-T-K9  5.280 to 5.320 GHz; ch56 / 60 / 64

I enounter fail when i adjust the AP1 txpower using cli 

ERROR Message as below

(Cisco Controller) >config 802.11a txpower ap CAP2602I-In-ShRoom ?

global Enables auto-RF.
<power level> Enter transmit power level

(Cisco Controller) >config 802.11a txpower ap CAP2602I-In-ShRoom 2

Radio [Slot 1] is not Disabled or Customize is not enabled

But If i Setup the txpower from GUI , it's ok and chanegd as expected 

DId I Key in wrong commmad to adjust AP1 txpower ? 

or Maybe GUI actually help me disable the AP , and enable the AP to change tx power 

I need AP1/ AP2 always be on status , because I want simlate the user moving between AP1/AP2 repeatly , 

If my WLC+AP is too old , please kindly tell me what WLC & AP and adjust the PowerLexel without turn off/On the Radio 

many thanks for you help & answer

 >....Note: If you get the error 'Radio [Slot 1] is not Disabled or Customize is not enabled', this means that the radio is in enabled state on the AP. You can disable the radio only on this AP with the command config 802.11a/b disable ap_name and then try to set the power level value. In order to re-enable the radio use the command config 802.11a/b enable ap_name
