Instruction Manual

Quick Start Guide

• Open the battery door — located on

the bottom of the device.

• Remove the yellow tab from battery.

• Place the battery in the door and close.

• Turn on by closing the battery door.

• Turn off by opening the battery door.

Note: Door will not close if the battery is inserted

incorrectly.

Note: Battery does not need to be removed if the

door is open far enough to turn off the device.

NOTE: Ear tips are reusable. Replace 3-ﬂange ear tips

every 60–90 days and foam ear tips regularly.

NOTE: Feedback (whistling) may be heard while

inserting the device until it is fully sealed in the ear.

It is perfectly natural. It will go away when the ear tip

is sealed in the ear.

TIP: Some people can ﬂip the switch when the device is

in the ear, but it is not unusual that you will have to take

it out of your ear to change the switch position.

Refer to page 20 for complete instructions and page24

for troubleshooting information.

The ear tip that is most comfortable and seals the

ear is the best choice.

To properly insert:

Pull ear up and out. Using a twisting motion,

position the device horizontally in the ear with

the switch toward the back of the ear.

LOW SETTING

Flip the switch toward the front of the device.

HIGH SETTING

Flip the switch toward the back of the device for

more sound.
