Step 9:
To replace the removable battery cover, start sliding the cover on at the bottom of the battery pack compartment and
slide cover upward to the top of the small opening until the cover latches back into place.
Step 10: Adjust the mic volume by using the + (plus) and – (minus) buttons on the front panel of the Wireless Receiver
and set the audio levels on the audio system to taste. The LED ladder will act as an LED meter and as a way to set the
levels when the volume buttons are touched and held. Test the mic ON/OFF switch on the Belt Pack and also the Mic
Mute switch on the Audio Interface for proper operation.
Step 11:
Set the Dip Switches on the Back Panel of the Audio Receiver for the requirements of the application. See the
AutoTrak 2.0 Manual for setting the dip switches internal to the Belt Pack (SW4 and SW5) and set these switches on
the for the requirements of the application as well.
Other Notes:
 The IR LEDs can’t be seen (if you are human - since the 850nm LED light is outside of human optical sensory
range) so make sure that the System Power on the Belt Pack Unit is off when it is not in use.
 If the Audio Level output is set to a high level, please avoid touching the mic element on the central medallion.
 If the System Power LED on the Belt Pack flashes, then the battery is low and a battery change is required.
