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]

  1. Screw an appropriate earpiece with the thread onto the hearing protection and press the earpiece together lightly with your fingers.
  2. 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.
  3. Rotate the hearing protection slightly until it is sitting securely in the visible part of your ear.
  4. Ensure that the hearing protection is seated close to the edge of the inner ear. If required, switch to larger or smaller ear­pieces.

  • Connect the mains adapter with the USB cable supplied.
  • Connect the USB cable with the charging port of the charging case.
  • Insert the mains adapter into a mains out­let.

The LED indicator of the charging case flashes during the charging process.

  • Wait until the LED indicator lights up com­pletely.

Checking the state of charge

The charging case and the hearing protection automatically show the state of charge on the LED indicator for ten seconds after opening the charging case.

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:

  1. This device may not cause interference.
  2. 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.

  1. The environmental noise level as meas­ured at the ear is 92 dBA.
  2. The NRR is 25 decibels (dB).
  3. 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.
