Note:
Everyone's ear canals are shaped differently. In fact, it is not
uncommon for the left and right ear canals to bend in different
directions, even in the same person. If you feel light resistance
when you first insert the D30 device, and it doesn't feel like it has
gone in all the way, the D30 device might just need a little help.
Give it a little nudge left, right, up, or down to see if you have a
bend in your ear canal, and if you can, nudge it around the bend so
it goes into place more fully. But PLEASE be gentle and don't force
it.
Make sure that the Earplug is correctly attached. In rare cases,
the Earplug could remain in your ear after removing the D30
device. If this happens, have the Earplug removed by a healthcare
professional.
If you apply hairspray or cosmetics, please do so BEFORE
inserting the D30 devices. Otherwise they could clog the
microphone. Likewise, if you apply hand lotion, please do so
AFTER the devices have been inserted, so the lotion does not clog
the microphone.
Consult your hearing care professional if you have difficulties
removing the hearing aid.
After removal, it's a good idea to inspect your devices for wax
buildup, or to replace the Earplugs or wax guards if needed. You
can read more about this in the D30 Care section
AMPLIFICATION LEVELS
Your D30 devices have four Volumes, ranging from different
amplification. To go from one volume to the next, switch the knob
for volume controll.
