HC05 Bluetooth module

I have an HC05 bluetooth module that i’d like to communicate with, but how can i enter AT or command mode? The datasheet suggests the following methods:

Mode 1: After power on, it can enter the AT mode by triggering PIN34 with high level. Then the baud rate for setting AT command is equal to the baud rate in communication, for example: 9600.

Mode 2: First set the PIN34 as high level, or while on powering the module set the PIN34 to be high level, the Baud rate used here is 38400 bps.

Are they suggesting placing current to PIN34, if so how much do i need to obtain “high level”? I would like to enter AT/command mode to make a few connection and password changes. Sorry if this is elementary.
