3M Peltor Lite-Com Pro II Mode D'emploi page 6

CHANNEL
Up to 30 radio channels can be used in the 403 – 470 MHz frequency range.
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 radio transmits when sounds of a certain volume reach the microphone – hands-free transmission.
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 "vox off". If you want to transmit, you must use the PTT button. To switch VOX on again,
press the UP (+) button.
NOTICE! For maximum noise cancelling, the speech microphone of the headset should be positioned
very close to your mouth (3 mm)! (Fig.G)
The use of a wind shield is also recommended (see "ACCESSORIES AND SPARE PARTS" below).
SQUELCH (Hiss reduction)
"Squelch" means that the background hiss in the earphones is prevented when the incoming signal is below a set level. When someone
speaks, the amplification returns instantly to the selected 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 and opens the receiver at the lowest incoming signal.
To switch squelch off, press and hold the DOWN (–) button for two seconds in squelch step one.
A voice message confirms "squelch off". To switch squelch on again, press the UP (+) button.
QUICK OFF/ON
When pressing DOWN (-) for two seconds from any menu, the actual menu level will be set to the lowest activated setting. For a
standard configured headset it should be level "off". One press on UP (+) shall activate the menu level before QUICK OFF. This function
is possible on SURROUND, RADIO, VOX, and SQUELCH.
SUB CHANNEL (Sub tones / Selective Squelch)
If "Sub Channel" is activated a certain tone or code will be transmitted along with the speech in order to "open" the receiver.
This allows multiple groups of users to use the same channel without listening to the other groups.
Notice! Any other radio communication, which does not include the selected tone or code, will be blocked by the filter!
Use the UP (+) and DOWN (–) buttons to activate the programmed sub-tone. A voice message confirms the new setting each time you
press the button. If the function is switched to OFF, all communication on the channel can be monitored.
Lite Com Pro II supports Continous tone coded squelch system (CTCSS) and Digitally Coded Squelch (DCS). Only one sub tone is
possible to configure for each channel, which is done by the dealer.
When BCLO or BTLO (busy channel or tone lockout) is enabled, VOX operation is not possible if the channel is already in use.
A warning tone may be heard in the speaker, when BCLO or BTLO is active (This function can be disabled). This prevents unwanted
interference with other muted communication on the actual channel.
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.
Medium power is recommended, where possible.
NOTICE: The operating time depends to a great extent on the condition of the 3M™ Peltor™ ACK08 battery
and how the 3M™ Peltor™ Lite-Com Pro II is used.
PTT (Push-to-talk)
Press PTT to transmit manually using the 3M™ Peltor™ Lite-Com Pro II 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 3M™ Peltor™ Lite-Com Pro II has BCLO and BTLO (busy channel and busy tone lockout) to block transmissions on busy
channels. See above "Selective squelch".
