1:F In-Ear Headset
In-Ear headset with electret microphone
An ambient microphone in each ear for listening to the external environment safely
Two internal speakers for listening to received audio
2. Assembly
Unpack the ORA TAC Carton, verify the following items are present:
• ORA TAC
• Two AAA batteries
• Eartips
2:A Attach eartips to the earbuds
2:B Attach the radio cable to the ORA TAC (To disconnect, press the small button
and pull apart.)
2:C Install two AAA batteries as shown, insert positive ends rst
2:D Connect completed assembly to the radio
3. Fitting and adjustment
Inserting the earplugs
The earplugs should be inserted in the ears according to the R/L (right/left) mark-
ings on the assembly.
Earplugs should be clean before tting.
INSERT rounded tip into ear canal WHILE PULLING ear outward & upward with
opposite hand.
See illustration 3:A
ADJUST for best noise reduction.
CHECK FIT after inserting plug:
PULL plug stem gently. Plug should not come out of the ear easily. If it does,
remove plug & repeat tting.
LISTEN to steady loud noise with plugs in both ears. Cover ears with tightly cupped
hands. Noise should sound about the same whether or not ears are covered.

If you cannot obtain a good t, try a different type of hearing protector.
CAUTION: For greater comfort and safety, remove plug slowly with twisting motion
to gradually break the seal.
Cable routing options
The headset includes a cable slide to allow alternate methods of routing the cables
based on user preference:
3:B Straight Down
3:C Over the ear in front
3:D Over the ear in back
4. Important user information
WARNING!
These hearing protectors help reduce exposure to hazardous noise and other loud
sounds. Misuse or failure to wear hearing protectors at all times that you are exposed
to hazardous noise may result in hearing loss or injury. If there is any drainage from
your ear or you have an ear infection, consult with your physician before wearing
earplugs. Failure to do so may result in hearing loss or injury.
Incorrectly inserted batteries can damage the electronics. Never replace the batter-
ies with the unit switched on. Make sure the + and - poles are in the correct position
before switching the unit on. Replace the batteries when interference increases or
the volume becomes too weak.
Remove the batteries when storing the hearing protector for extended periods of
time. Check the functioning of the unit after replacing the batteries.
IMPORTANT!: Always make sure that the volume on the com radio, intercom system
or other connected equipment is set to a low level before inserting the plugs into your
ears. Adjust the volume to a comfortable level afterwards.
• The hearing protector must be worn, adjusted, cleaned and maintained in
accordance with this manual.
• The hearing protector features level dependent. Check that this feature works
before using the unit. If distortion or aws are discovered, consult the instructions
for maintenance and battery replacement.
• Always wear the hearing protector at all times during exposure to hazardous
noise
• Certain chemical substances may damage this product.
Contact the manufacturer for more information.
• The hearing protector is tted with an electric audio input.
Check correct operation before using the unit. If distortion or failure are discov-
ered, consult the manufacturer’s instructions.
• If sound distortion increases or the volume becomes too weak, it is time to charge
or replace the batteries. Never replace or insert batteries with the unit switched on.
Ensure that the batteries are correctly aligned before using the product.
• Store product without the batteries.
• Under extremely cold conditions, warm the hearing protector before using.
• The wearer should ensure that the ear plugs are regularly inspected for
serviceability.
• The audibility of warning signals at a specic workplace may be impaired while
using the entertainment facility.
• The performance may deteriorate with battery usage.
Note: If these recommendations are not followed, attenuation may be adversely
affected leading to hearing impairment.
WARNING!
The output from the level dependent circuit of the hearing protector may exceed the
daily limit sound level
WARNING!
Performance may deteriorate with battery usage. The typical period of continues use
that can be expected from the product is 400 hours

WARNING!
These ear plugs should not be used where there is a risk that the connecting cord
could be caught up during use.
WARNING!
If these recommendations of use, storage and maintenance described in this user
instruction are not adhered, the protection afforded by the ear plugs will be severely
impaired.
5. Technical Data
5:A Attenuation values, SNR
The nominal range of diamters of the ear plugs are 8-12 mm
The attenuation values are tested and approved according to PPE directive 89/686/
EEC and applicable sections of standard EN 352-2:2002 and EN 352-7:2002
Certicate issued by FIOH, Topeliuksenkatu 41, FI-00250 Helsinki, Finland, ID#0403.
Explanation of the attenuation data tables:
1. Weight
2. Frequency (Hz)
3. Average attenuation (dB)
4. Standard deviation (dB)
5. Expected attenuation (dB)
5:B Input signal level/usage time for audio input
Electrical audio input of the earplugs was measured in accordance with in-house-
method derived from those described in standard EN 352-6:2002
Maximum permitted audio signal in relation to usage time.
To prevent harmful effects on hearing, the input signal should not exceed the
specied values (average speech sound level). The long-term average value of the
earphone volume is measured at a level corresponding to no more than 82 dB(A)
sound level. Electrical input level for which the mean plus one standard deviation
A-weighted diffuse-eld related sound pressure level is equal to 82 dB is at RMS-
voltage U = 29 mV.
5:C Criterion levels (G)
A criterion level is the amount of noise (measured as A-weighted sound pressure)
outside the hearing protector that gives 85 dB(A) inside. The noise level depends on
the type of noise. H is high-frequency dominated noise, M is noise that is not domi-
nated by any given frequency, and L is low-frequency dominated noise.
5:D Battery type
2 X AAA 1.2–1.5V
5:E Battery life : ~ 400h (5% talk, 5% listen, 90% On time)
The expected battery life may vary depending on the brand of batteries and the tem-
perature in which the product is used. A Low-Battery condition will generate 3 beeps
that repeats every 10 seconds until the batteries are replaced.
5:F Storage & Operating Temperature
Operating Temp: -32°C to +55°C
Storage Temp: -32C° to +63°C
Storage humidity: ‹ 85%
Shelf life ‹ 5 years
5:G
