Set SQ switch
The SQ switch is inside the battery compartment next to the Battery Select switch. The unit
is shipped with SQ in the ON position. To turn it off, use a small screwdriver or pen to slide
the switch to the OFF position (to the right). See page 58 for more information on SQ.

Place Batteries in Unit

Place two AA batteries in the compartment, making note of the battery polarity
shown in the battery compartment, and again verifying that the BATTERY
SELECT switch is in the correct position for the batteries you are using. (ALK
should be selected for all battery types other than NiMH).
NOTE: Listen uses 1800mAh (milli-Amp-hour) constant current NiMH
(Nickel Metal Hydride) batteries. These may be purchased from your Listen
dealer (ask for part number LA-362).

Connect an Earphone or Headset

Your headset or earphone will connect to the jack on the top of the unit. Either mono or
stereo connectors may be used with a Listen receiver. Make certain you push the plug all the
way into the jack.
