AUXILIARY INPUT LEVEL
The auxiliary input level can be used to adjust the auxiliary input level only. To adjust, open the battery
door and locate the Auxiliary Input Level (see FIG 4). Use the supplied small screwdriver and rotate to
increase “+” or decrease “-” the input level.
Note: When using an auxiliary audio source, if the “Aux Input Level” is set too high, there can be in-
creased audio distortion and decreased battery life.
Note: Microphone cable serves as the transmitting antenna; therefore must remain plugged in during Aux
cable use.
COMPRESSION SELECTOR
By default, the PFM T36 compression is set to “Off” for normal operation, or “1:1” compression. For
hearing assistance applications, the compression selector can be set to “On” for “2:1” compression.
To change this setting, open the battery door and locate the Compression Selector (FIG 4). To turn on
compression, use the supplied small screwdriver and slide the “Comp” switch to the position marked
“2:1”. To turn off compression, slide the “Comp” switch to the position marked “1:1”.
CHANNEL LOCK
By default, the PFM T36 channels are unlocked to allow the user to change frequencies as needed. If
desired, channels can be locked to prevent users from changing the channels.
Note: The Channel Lock only locks the electronic frequency; it does not physically lock the channel selec-
tion knob.
To lock or unlock channels, open the battery door and locate the Channel Lock (FIG 4). To lock the cur-
rent channel while the unit is on, slide the “CH Lock” switch to the position marked (
