Setting audio attenuation

When using a KTD-336 audio converter, set the attenuation jumpers to the ON position (Figure 13). The
attenuation jumpers are located on the audio/IO card, which is attached to the keypad's base plate. When not
using an audio converter, leave the attenuation jumpers in their default OFF position.
