Symbols
Warning of general danger
Read the operating manual and safety warnings.
CE marking: Confirms the conformity of the device with EU guidelines.
UKCA marking: Confirms the conformity of the product with UK regulations.
Do not dispose of the device with the domestic waste.
Safety warnings
WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this de vice. Failure to observe the instructions and safety warnings may lead to electric shocks, fires and/or serious injuries, e.g. hearing damage. If there are distortions or outages, please contact the Festool customer service team (see section 7). The battery must not be replaced. Save all warnings and instructions for future reference.
- Do not use the charging case in the rain or in a damp environment. Moisture in the device may cause a short circuit and fire.
- Do not insert any nails, wire or similar into the USB port. This could cause the tool to short-circuit, smoke or catch fire.
- Only charge the device using chargers with a voltage of max. 5 V. Using higher voltages would be a fire risk.
- Audibility of warning signals. Ensure that warning signals can continue to be heard at the workplace and in other environments when using the audio function.
- Keep the device away from children. Small parts that could be swallowed are included.
- Silicon earpieces are not suitable for noise reduction. Only use silicon earpieces for audio functions.
- Ensure that the earpieces used are the right size. Using earpieces that are not correctly seated may damage your hearing. Earpieces that are too small do not provide full hearing protection.
- Earpieces that are too large can remain stuck in the ear canal when you try to remove them.
- The hearing protection must be worn continuously in noisy environments.
- Sudden or fast removal of the hearing protector can cause damage to the eardrum.
- The hearing protection is equipped with level-dependent attenuation and a safety-relevant audio input. Check correct operation before use.
- The typical period of continuous use that can be expected when fully charged is 13 hours. Battery life performance may deteriorate beyond this time and with normal usage.
- The output of the audio circuit of the hearing protector may exceed the exposure limit level.
- The hearing protection has an audio entertainment function. The hearing protection has a sound pressure limiting feature for the audio signal which effectively limits the audio signal for entertainment media to under 82 dB(A) (GHS 25 I) / 85 dB(A) (GHS 25 I US) for your ear. This limit is maintained for Bluetooth® signal inputs which are standard to the Bluetooth® A2DP specifications.
Intended use
- The hearing protection is used to reduce ambient noise by or to screen ambient noise >79 dB (GHS 25 I) / >85 dB (GHS 25 I US).
- The device enables telephone calls to be made and audio signals to be transmitted.
- The device must NOT be used in environments in which the user needs to be fully aware of their surroundings, e.g. when driving a car.
The device must NOT be used in potentially explosive environments.
warning: The user is liable for improper or non-intended use.
Approval for noise attenuation. The device has been tested in accordance
with the
EN 352-2:2020 (SNR) and ANSI S3.19-1974 (NRR) standards for hearing
protection. The sound attenuation value is based on continuous noise and is
therefore not an accurate value for the reduction of impulse sound.

Commissioning
Inserting the hearing protection [1]
- Screw an appropriate earpiece with the thread onto the hearing protection and press the earpiece together lightly with your fingers.
- Insert the hearing protection with the earpiece as deeply into your ear as is comfortable. Correctly insert the left and right side, as indicated by the marking on the hearing protection, into your left and right ear respectively.
- Rotate the hearing protection slightly until it is sitting securely in the visible part of your ear.
- Ensure that the hearing protection is seated close to the edge of the inner ear. If required, switch to larger or smaller earpieces.

Federal Communications Commission (FCC) Interference Statement
NOTE: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
NOTE: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
FCC ID: 2AL2E-GHS25
RSS Compliance Statement: This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions:
- This device may not cause interference.
- This device must accept any interference, including interference that may cause undesired operation of the device.
Canada: Radio frequency (RF) Exposure Information
The radiated output power of the Wireless Device is below the Innovation,
Science and Economic Development (ISED) radio frequency exposure limits. The
Wireless Device should be used in such a manner such that the potential for
human contact during normal operation is minimized.
USA: ANSI S3.19-1974
The level of noise entering a person’s ear, when hearing protector is worn as
directed, is closely approximated by the difference between the A-weighted
environmental noise level and the NRR.
- The environmental noise level as measured at the ear is 92 dBA.
- The NRR is 25 decibels (dB).
- The level of noise entering the ear is approximately equal to 67 dB(A).
CAUTION: For noise environments dominated by frequencies below 500 Hz the
C-weighted environmental noise level should be used.
Although hearing protectors can be recommended for protection against the
harmful effects of impulsive noise, the Noise Reduction Rating (NRR) is based
on the attenuation of continuous noise and may not be an accurate indicator of
the protection attainable against impulsive noise such as gunfire.
Improper: fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit.ANSI S3.19-1974 testing was performed by Michael & Associates, Inc.
