INSTRUCTIONS FOR USE/SETTINGS

ON/OFF/MODE
Switch the Lite-Com Pro on and off by pressing and holding the ON/OFF/MODE button for about 2 seconds. A tone confirms that the unit has been switched on or off. A slowly blinking LED on the button shows that the Lite-Com Pro is on. When the unit is transmitting or receiving, the LED blinks faster. Press ON/OFF/MODE (¡) briefly to move through the menu. Press the button slowly, one step at a time, to confirm each step in a voice message. If you press the button faster, you will only receive voice confirmation of the function where you stop.
Current settings are stored when the unit is switched off.

SURROUND (ambient noise level)
Ambient sound amplification – when the Lite-Com Pro is used as an active hearing protector – is regulated with the UP (+) and DOWN (–) selectors. The change is confirmed with a voice message. You can also switch off ambient noise by reducing the volume to its lowest position using the DOWN (–) button, then holding the button for about 2 seconds. A voice message says “SURROUND OFF”, confirming that the ambient noise has been switched off.
WARNING! This setting attenuates ambient noises through the hearing protector, and they may become inaudible. To re-activate the function, press UP (+) and the Lite-Com Pro once again works as an active-volume hearing protector that limits volume.

VOLUME
Use the UP (+) and DOWN (–) buttons to set the incoming volume in the communication radio. A voice message confirms the new setting each time you press the button. There are max. 7 volume steps and an off mode. To access off mode, press and hold the DOWN (–) button for two seconds when at the lowest volume. A voice message confirms “VOLUME OFF”.

Note: No radio communication is audible in off mode.
To switch the radio back on, press the UP (+) button. You start receiving on the lowest volume level.

CHANNEL
Up to 30 channels can be used in the 430–470 MHz frequency range. (Contact an approved Peltor dealer to program your unit.)
Use the UP (+) and DOWN (–) buttons to select a channel (radio frequency) for the communication radio. A voice message confirms the new setting each time you press the button.

VOX (Voice-operated transmission)
VOX means that the Lite-Com transmits when sounds of a certain volume reach the microphone  hands-free transmission.
The Lite-Com Pro also has busy channel lockout (BCLO), which means that voice- operated transmission is not possible if the channel is already in use. This prevents interference.
Use the UP (+) and DOWN (–) buttons to set the sensitivity for voice-operated transmission. A voice message confirms the new setting each time you press the button. There are five VOX levels and an off mode. To access off mode, press and hold the DOWN (–) button for two seconds. A voice message confirms “VOLUME OFF”. If you want to transmit, you must use the PTT button. To switch VOX on again, press the UP (+) button.

Note: For maximum ambient-noise compensation, position the microphone on the headset no less than 3–5 mm from the lips.

SQUELCH (hiss reduction)
Squelch means that the noise in the earphones is reduced when the incoming signal is below a set level. This way, the user doesn’t have to listen to background hiss. When someone speaks, the amplification returns instantly to the proper level. Use the UP (+) and DOWN (–) buttons to set the squelch level. A voice message confirms the new setting each time you press the button. There are five SQUELCH levels and an off mode. Level 1 is most sensitive, renewing amplification at the lowest input signal. To access off mode, press and hold the DOWN (–) button for two seconds in volume step one. A voice message confirms “SQUELCH OFF”. To switch VOX on again, press the UP (+) button.

SUB CHANNEL (Selective reception)
When a radio receiver has selective reception, a certain tone or code must be transmitted along with the speech in order to be received. This allows multiple groups of users to use the same channel without interfering with each other.
Use the UP (+) and DOWN (–) buttons to set the subchannel. A voice message confirms the new setting each time you press the button. There are 38 analogue CTCSS tones and 83 digital DCS codes. They are programmed with numbers 1–121 (see table F on the inside cover). If the function is switched to OFF, all communication on the channel can be monitored.

POWER (output)
There are three output power levels : High, medium and low. Use the UP (+) and DOWN (–) buttons to select the output power level. A voice message confirms the new setting each time you press the button. We recommend using MEDIUM POWER where possible.

Note
The battery life/operating time depends to a great extent on the type and condition of the batteries
and how the Lite-Com Pro is used. For example, with an alkaline battery with at least 2700 mAh, the operating time in low-power mode is about 40 hours at 15% transmission and 85% reception/stand-by. In high-power mode, the operating time under the same conditions decreases by about 20%. With 20% transmission and 80% reception/stand-by, the operating time is about 35 hours at medium power.

TA BORT PTT (Push-to-talk)
Press PTT to transmit manually using the Lite-Com Pro radio.

Notes

1. Switch voice control (VOX) on and off by pressing the button briefly twice. A voice message, “VOX on” or “VOX off” confirms the setting.
2. The Lite-Com Pro has busy channel lockout (BCLO) to block transmissions on busy channels.

Note: When using the Lite-Com in environments with a risk for explosions, ATEX-approved batteries are required! Never change batteries or charge accumulators in an explosive environment!
Only the following types of batteries are currently approved for use in the Peltor Lite-Com Pro in explosive environments:

Peltor’s ACK05 NiMH accumulator is included with the product. Charge only with the included FR05 charger.
In a non-explosive environment, other accumulator batteries or 1.5-volt AA alkaline batteries can be used.
Install the batteries under the battery cover. Make sure that the + and – poles of the batteries are in the correct position (see the figure in the cover).

WARNING! If you use rechargeable batteries, charge them only according to the charger manual. Dry-cell batteries can explode if recharged.
Never charge batteries or accumulators in an explosive environment!

ASSEMBLY Headband (Fig. J)

Slide out the cups and place the headset over your ears so that the ear cushions fit snugly. Adjust the height of the cups to a snug, comfortable fit by sliding the cup up or down while pressing the headband down.
The headband should lie across the top of the head.

Helmet attachment (Fig. K)
(K:1) Snap the helmet attachment into the slot on the helmet.

Note: The cups can be set in three positions: Working position (K:2), ventilation position (K:3) and parked position (K:4). When in use, the cups must be placed in working position. Press the headband wires inwards until you hear a click on both sides. Ensure that the shell and the headband wires in working mode do not press against the lining or edge of the helmet so that noise leakage can occur.
100% use of a working hearing protector is the only sure protection from hearing loss.
If you spend time in environments with more than 82 dB A-weighted noise, you need to protect your hearing, or the hearing receptors deep in your ears may be irreparably damaged. If you remove the protectors for even a tiny portion of the time you spend in noisy situations, you are in the danger zone. A comfortable hearing protector designed for the specific noise level in which it is used is the best guarantee that you will wear the hearing protector 100% of the time, thereby ensuring protection from permanent hearing loss. For the best protection, brush aside hair around the ears so the ear cushions fit snugly against the head. Spectacle frames should be as thin as possible and fit close to the head.

WARNING! The external input does not have an automatic volume limit. You must limit the volume on the external equipment manually. (D:2)

MAINTENANCE

Clean the outside of the headset regularly with soap and warm water.

Note: Do not immerse in fluids.
After long hours of use, or other situations in which the Lite-Com Pro is exposed to moisture inside, the hygiene kit should removed so the hearing protector can dry before the next use. Do not store the headset in temperatures exceeding +55°C, for example on a dashboard or windowsill. The headset
(especially the ear cushions) can wear out over time. Inspect them often and regularly to ensure that there are no cracks or sound leakage. Certain chemical substances may be harmful to this product. Contact Peltor for more information. When the battery low warning sounds, it is time to replace the batteries. The unit switches off automatically after a few minutes. Never replace or install batteries with the unit switched on. Before switching on, make sure that the batteries are inserted correctly.
Always wear, adjust, clean and maintain the headset according to these instructions. If these recommendations are not followed, attenuation and other functions can be impaired.

(D) INPUT SIGNAL/OPERATING TIME
Warning: The volume of the earphones in this hearing protector can lead to a daily exposure that exceeds the permitted levels. The audio signal must therefore be adapted to the operating time. To prevent harmful levels, the input signal should not exceed 22 mV. At a higher input voltage, the operating time must be decreased according to diagram D:1 (x=22 mV). An electrical input signal of 22 mV(RMS) corresponds to 82 dB (A) equivalent sound level (average value plus one standard deviation of the measured sound level. See table D:2). Note: The maximum output effect of the earphones must not be exceeded.
