Step 2e: Program the function
switch for T-coil and FM/DAI

SUMO's programmable function switch, marked M-1-2, allows for a variety of user configurations.
After the appropriate switch function has been selected for the user, consider activating the Telecoil
Boost, which adds 6dB to the response. The Telecoil in SUMO closely matches the microphone
response. In most cases, the client can also use the VC to further improve the telecoil strength.

FM/DAI fitting tips:

1)

When using the SUMO FM 

adapter shoe (part# 399-50-920) 
and a plug-in FM receiver, SUMO's
default switch setting becomes:

M = Microphone
1 = Micr FM
2 = FM only

The switch on the FM receiver
should be set at FM + M. SUMO's
function switch should be used to
choose between FM + M (position 1)
or FM only (position 2).

2)

With a DAI shoe attached, 

SUMO's default switch setting
becomes:

M = Microphone
1 = Micr DAI
2 = DAI only

3)

The T-coil in SUMO can only be

used when the FM receiver or DAI
shoe is removed.
