SOMEONE HELP ME TURN THIS KEYPAD SOUND OFF!

Hi all! I have a Honeywell K4392V2-H M7240 and the keypad is SO LOUD when entering any code / command. IS there a way to silence it? I've been looking online and I have only found ways to silence the chime, but I want the actual keypad silenced or at least turned down. When my husband leaves for work at 6AM it wakes up the whole house. LOL going insane. TY!!!
