1. Overview

Definition: This command sends the -79dB setting into the volume control hardware register(s) corresponding to the value in the <param> character. None of the corresponding volume-level EEPROM variables are modified.

If the command is properly received, the CAT 860 responds by repeating back the command packet where the <Param> character contains the mute selection status.

If the command is not received properly, the CAT 860 responds by sending a <NACK> character.

Basic Command Set.

Definition: Based on the value in the <param> character, this command unconditionally sends the appropriate EEPROM variable content(s) into the corresponding volume control hardware register(s). None of the volume-level EEPROM variables are modified.

If the command is properly received, the CAT 860 responds by repeating back the command packet where the <Param> character contains the un-mute selection status.

If the command is not received properly the CAT 860 responds by sending a <NACK> character.

Note: The un-mute operations will override any mute operations performed as part of any command from the Basic Command Set.
