CC2530: transmit power

hi

I want to set my cc2530pa1 transmit power to some arbitrary value for example 23dBm and I did the things listed below:

- set the txPwrTblIdx = 23; in mac_radio_defs

- added the library to my zcl_"sample app".c file: #include "mac_low_level.h"

- called the function in my zcl_"sample app".c file: macRadioSetTxPower(23); 

is it right or enough or I should do something else???
