• Make sure the eartip is clean.
• Pull the ear up and out while
inserting (Fig. 1).

eartip seals in the ear canal.
(Fig. 2).
• When using 3-flange eartips,
moistening may ease insertion.
• When using foam eartip: Roll
down or compress foam eartip
before inserting. Hold the eartip
in place for about 5 seconds
while foam expands to create
a tight seal in the ear canal
(Fig. 3).

LOBAT™: A ticking sound becomes faster and louder,
like the sound of a motorboat when the battery is
about to die. After the warning sound first becomes
audible, it may be a few hours before the battery
dies. Performance and protection do not change
while OBAT™is sounding.
Low Ba ery Warning
Warn ng: Performance may deteriorate with battery
usage. The typical period of continuous use that can
be expected from the battery is 300 hours.
Battery life is estimated at 2-3 weeks for continuous
operation. Each device uses one #312 zinc-air battery.
It is not necessary to recycle this battery. Zinc-air
batteries are not harmful to the environment and
can be discarded in the trash. Keep batteries out of
the reach of children.
Recommendat on: Carry spare batteries in case
batteries reach end of life during use.
