SAFETY

General safety

WARNING!

  • Use and save these instructions.
  • The protection afforded by earmuffs will be severely impaired if you do not follow the instructions in this operator’s manual.
  • The wearer should ensure that,
    – the earmuffs are fitted, adjusted, and maintained in accordance with this manual.
    – the earmuffs are worn at all times in noisy environments.
    – the earmuffs are regularly inspected for serviceability
  • This hearing protector is provided with level-dependent attenuation. The wearer should check correct
    operation before use. If distortion or failure is detected, the wearer should refer to the manufacturer’s advice for maintenance and replacement of the battery.
  • Performance may deteriorate with battery usage. The typical period of continuous use that can be
    expected from the hearing protector battery varies depending on the mode of use and volume output. The typical period of continuous use in ambient mode with mid-volume is 36 hours.
  • The output level-dependent circuit of this hearing protector may exceed the external sound level.
  • This hearing protector is provided with an entertainment audio facility. The entertainment (FM Radio and Bluetooth streaming) audio signal sound pressure level is limited to 82dB(A) effective to the ear.
  • The audibility of warning signals at a specific workplace may be impaired while using the entertainment facility.
  • This product may be adversely affected by certain chemical substances. Further information should be sought from the manufacturer.
  • Clean the product regularly. Use a cloth with water and soap. Do not wash or put fully into the water.
  • Hearing protectors, and in particular, cushions may deteriorate with use and should be examined at frequent intervals for cracking and leakage, for example.
  • The fitting of hygiene covers to the cushions may affect the acoustic performance of the hearing protectors.
  • The product contains a battery and electrical components that may cause ignition inflammable or explosive atmospheres. Do not use in environments where sparks may cause a fire or explosion.
  • Do not put the product in storage at temperatures above +55°C and below -20°C.

OPERATION

Introduction

WARNING!

Before you operate the product, you must read and understand the safety chapter.
Before following the fitting instructions, move your hair aside and remove any objects that could affect the acoustic seal. Make sure that the sealing rings are tight around your ears before you operate the product.
To put the hearing protectors in operating position (Sordin SHARP-1): Place the cups over the ears and adjust the headband and cups until they are in a comfortable position. Adjust the earmuffs until they are tight around your ears and tight against your head. (Fig.2)
To assemble the hearing protectors to a helmet (Sordin SHARP-2): Lift the earmuffs out and up until they lock in the standby position. (Fig.3). Put the helmet attachment in the slot on the helmet. (Fig.4) For further tips on cable routing, visit www.sordin.com; search for SHARP.
To put the hearing protectors in operating position (Sordin SHARP-2): Put the helmet on your head.
Adjust the earmuffs until they are tight around your ears and tight against your head. (Fig.5)
To put the hearing protectors in standby position (Sordin SHARP-2): Lift the earmuffs out and up until they lock in the standby position. (Fig.6) To put the hearing protectors in parking position (Sordin SHARP-2): Put the earmuffs in the standby position. Turn the hearing protectors rearward along the side of the helmet until they lock in the parking position. (Fig. 7)
Do not press the earmuffs against the helmet shell as this can cause cracks around the side of the helmet. (Fig. 1)
To attach/remove optional head padding (SHARP-1): The optional head padding can be attached/ removed. Open the velcro flap on the padding to remove it from the headband.
The hearing protector is equipped with integrated microphones. A boom microphone can be used in noisy environments to decrease the noise during phone calls and two-way radio calls.
To assemble the boom microphone: Make sure that the hearing protector is off and connect the boom microphone to the microphone input on the right earmuff. (Fig. 9)
To charge the battery: Connect the charger cable to the charger jack on the left earmuff. (Fig. 10) Connect the USB connector on the charger cable to a standard USB charger.
Voice feedback: BEEP sound (Informs that the hearing protector is charging).

Do not wash or put fully into the water. Clean the product regularly. Use a cloth with water and soap and dry them carefully. Check the condition of the sealing rings and the foam rubber inserts before each use. Replace the sealing rings and the foam rubber inserts 1 time every 6 months or more frequently if it is necessary. Use original spare parts (Fig. 8 and Table 3). See Fig. 8 for how to replace the hygiene kits. Visit www.sordin.com for ordering information.

TRANSPORTATION, STORAGE, AND DISPOSAL
Transportation and storage 

When the hearing protector is not in use, store it in a dry and clean place at normal room temperature and do not place it in direct sunlight.

  • Make sure that the sealing rings are not compressed.
  • Make sure that the headband is not stretched (Sordin SHARP-1).
  • When the helmet is not in use, put the earmuffs in the operating position.

NOTICE! If the hearing protector is stored for a prolonged period, charge every 4 weeks to maintain the battery.
NOTICE! Do not press the cups onto the helmet shell as this will lock the spring in the earmuff arm, and damage the attachment slots on the side of the helmet (Sordin SHARP-2) (Fig. 1).
