These are the receivers used on all of the Signia Pure AX, Pure IX and Styletto AX models of hearing aids.

S - Standard receivers are the least powerful. Used for mild to moderate hearing losses. They are available in sizes 0, 1, 2, 3, 4 & 5.

M - Medium receivers are the middle power level. Used for moderate to moderately severe hearing losses. They are available in sizes 0, 1, 2, 3, 4 & 5.

P - Power receivers are the most powerful. Used for moderately severe to severe hearing losses. They are available in sizes 0, 1, 2, 3, 4 & 5.

PLEASE NOTE: It is very important that you do not change the power level of the receiver without a visit to your hearing health care specialist for programming changes. If done, it will change the volume levels and frequency response of the hearing aids. This will result in a reduction in sound quality and the potential to cause further damage to your hearing.
