# Recording Voice Messages is an Optional Step

Your Catalyst comes with default voice messages for all channels. The specific default messages for a given channel depends upon the configured channel type. Recording voice messages can be postponed until you have become more familiar with your RTU. You may choose to record or re-record your own message from a remote telephone or the front panel at any time.

Note: Before recording speech messages, be sure you have resolved which channels are analog types and which are discrete types. If there is any concern about total available recording time, you should also have determined the amount of memory to allocate to a Log File, if you plan to create one. Please refer to Log File Buffer Size Considerations . Also, be sure to review the topic Messages in the Operator's Manual.
