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 acoustic seal. Make sure that the sealing rings are tight around your ears before you operate the product.

Headband Version (left/RIGHT CC-1 and CO CC-1)
Make sure to put the headband the right way round. The inside of the headband is marked with a letter L on the left hand side and a letter R on the right hand side. Ensure that the headband is positioned correctly . With the headband over the head, adjust the height of the cups by sliding them up or down, so they completely enclose the ears.

Helmet Mounted Version (left/RIGHT CC-2 and CO CC-2)
These hearing protectors should be fitted to, and used only, with industrial safety helmets and adapters listed in Table 2. An adapter kit is provided with the the device. Before the hearing protectors can be attached to the helmet, the correct adapter have to be installed. The adapter number can be found on the adapter.

1. Attach the correct adapter  to the helmet.

2. Ensure that the cups are mounted on the correct side of the helmet. The cup marked with L must be put on the left-hand side of the helmet and the cup marked with R must be put on the right-hand side of the helmet.

3. Pull the ear cup down the fork as far as possible and put the cup in a stand-by position.

4. Push the attachment clip firmly into the slot on the side of the helmet until it clicks into place.

5. Detach the head harness at two places at the rear of the helmet and place the cord from the cups above the harness attachment. Reattach the harness. Ensure the cord is not tangled.

6. For the working position, press the cups toward the ears until they click into place. Adjust the height of the cups by sliding them up or down so they completely enclose the ears.

7. Stand-by position: Pull the cups away from the ears until they lock into the standby position.

8. Parking position: From the stand-by position, rotate the cups to the rear of the helmet until they click into place. In this position, the cushions do not get damaged or dirty and the cups can dry.
   NOTICE! Do not press the cups onto the helmet shell as this will lock the spring in the cup arm, and damage the attachment slots on the side of the helmet.

9. Storage position: When the helmet is not in use, lower the cups and push them inwards until they click into place.

FUNCTIONS

Switch ON / OFF
Switch on the electronics by pressing the key [O]. To switch it off, press the same key [O] and hold for 2 seconds.

Volume Adjustment
When powered up, the default mode is volume mode. Adjust the volume with the [+] or [-] button on the right cup. The volume has six fixed settings. When pressing the volume buttons, a short beep sound is heard. When reaching min or max volume, a long beep sound is heard.

Noise-Cancelling Boom Microphone
The earmuffs are equipped with a noise-canceling speech microphone that is specially designed to work in noisy environments. The product is supplied with an electret microphone. Adjust the boom microphone so that the microphone is level with your mouth and about 3–5 mm from your lips. It is important not to exceed this distance when working in a noisy environment, in order to get the best performance from the noise-canceling microphone. We recommend that you keep the microphone in this position whether you are talking or not. A wind protector should be used to prevent interference from wind noise.

Ambient Sound Listening (left/RIGHT CO CC)
These hearing protectors are equipped with electronics for reproducing ambient sounds (level-dependent function). Ambient sound is captured by two externally mounted microphones (Fig.G3) and reproduced by speakers inside the cup at a safe level. The sound is reproduced in stereo to preserve or improve direction location. This function is intended for use in environments where there is a need to hear ambient sound, such as warning signals, conversation and traffic. NOTICE! If the hearing protector is swiched off, incoming signals from communication radio or mobile phone cannot be heard. The lowest volume level shuts of the ambient listening.

Battery Saving Function (left/RIGHT CO CC)
To maximize battery life, the product is equipped with a battery-saving function. This function automatically switches off the electronics after 4 hours if none of the keys is pressed during this period. To switch it back on, press the key in the middle of the keypad (O). About 2 minutes before automatic switch-off occurs, a series of beeps will be heard as a warning that the hearing protector is about to be switched off. Press any key to delay switch-off by a further 4 hours.

Low Battery Warning (left/RIGHT CO CC)
Two tones will be heard when about 10-20 percent of the battery life remains. The battery warning is repeated every half hour until the batteries are completely discharged.

Battery Replacement (left/RIGHT CO CC)
The product must be equipped with two standard alkaline batteries, 1.5 V AA/LR6. The use of rechargeable batteries such as NiMH 1.2 V or NiCd 1.2 V will significantly reduce the operating time. The battery compartment is located in the left cup. To install new batteries, remove the lid (Fig.E1) and insert the batteries. Make sure that the + and  poles are correctly aligned (Fig.E2). Replace the lid. The product should be turned off during battery replacement.

Cable and Contact
The hearing protector is equipped with cable and plug for connection to external communication devices, like communication radios or mobile phones.

Push To Talk (PTT)
The PTT button is placed behind the boom microphone on the left ear cup (Fig.H).

• Connect the headset to the communication radio or mobile phone.
• Switch the communication radio on and adjust the volume to the desired level.
• Keep the PTT button pressed while transmitting and release the PTT button to receive if you connect the headset to a communication radio.
• Push the PTT button shortly to answer or hang up if you connect the headset to a mobile phone.
• Incoming radio signals will be heard in both the right and left cup.

MAINTENANCE

WARNING !

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.C1 and C2 and Table 3).

TRANSPORTATION, STORAGE, AND DISPOSAL

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

• Make sure that the sealing rings are not compressed.
• Make sure that the headband is not stretched (left/RIGHT CC-1 and CO CC-1).
• When the helmet is not in use, put the earmuffs in operating position.

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 (left/RIGHT CC-2 and CO CC-2) (Fig.B6).
Disposal
Follow national regulations for disposal of product.
