        Tech Tips


        • Each setting is reflected when going back to the normal mode.

        • The initial setting is "0000".

        • Each number can be set to from "0" to "2". Each quality gets well as each number increases.

        • If each number is set to from "3" to "9", the setting is ineffective.

        • Echo and half duplex have opposite performances, as well as noise and voice quality. So, when "1000" is inputted, echo is "1" and half duplex is determined to be equal to "-1" even though displayed as "0". Also, you cannot increase these opposing level simultaneously. So, when echo is set to "1" or "2", half duplex needs to be set to "0". If "2100", "1100", "0022", or "0012" etc. are inputted, the setting is ignored.
