Which, of the thousands of listed repeaters are you referring to?
Irregardlessly of which repeater you want to use, the basic steps are to request-access to the pacific repeater you wish to use. The repeater owner will then "approve" or deny your request and send you the TX and RX tone and channel/frequency..
IF the repeater you wish to use is "open", then no request is necessary and you should see all the info you need on the pacific page for the pacific repeater you want to use.
IF you meant something else, please elaborate.
