11 Modes of operation

Analog FM

Analog communication radio supports FM modulation so it could communicate with other analog radios on

the market that also support FM modulation. It also have support for sub tones, both CTCSS (1 - 38) and

DCS (39 - 121) tones. Analog communication radio has the possibility to set different frequencies for

receiving and transmitting. This to ensure that the headset could communicate in a repeater system.

DMR:

Digital communication radio supports DMR standard (tier 1 and tier 2) so it could communicate with other

digital radios on the market that also supports DMR standard (tier 1 and tier 2). Headset supports a digital

sub tone called color codes (0 – 15). DMR consists of three different communication modes: All call, group

call and private call. With all call you could communicate with all DMR headsets on the same frequency

and color code. With group call you could communicate with all headsets on the same frequency, correct

color code and correct group ID. With private call you could communicate with all headsets on the same

frequency, correct color code and correct radio ID. Digital communication radio has the possibility to set

different frequencies for receiving and transmitting. This makes it possible to communicate with a repeater

system.

Level Dependent:

At each cup there is one microphone mounted which receives the environmental sound and plays it to the

end user via the speakers inside the cups. If the sound outside the cups should exceed 82 dB it will be

automatically limited so no harmful sound levels will ever reach the end users ears. If the end user has turn

this volume to off or a low level there is a push to listen (PTL) function which could be activated by double

press on menu button. This will raise the level dependent volume to a preset volume level and at the same

time it will pause the audio stream if any. To exit PTL mode press any other button.

Bluetooth:

Bluetooth comes with four different profiles installed. HS/HF profile, A2DP, AVRCP and a PTT profile.

WS™ LiteCom Pro III is also equipped with Bluetooth multipoint. With Bluetooth multipoint it is also

possible to connect two Bluetooth equipped devices at the same time. Latest paired device will be the

primary device. It is only possible to control the primary device from the headset. If there is an incoming

call on the secondary device it will automatically be primary device and it is possible to answer the call

with the headsets Bluetooth button.

Phone HS/HF and PTT profile:

HS/HF profile handles all call functions such as answer, hang up, reject and voice dial. PTT profile is active

when an external communication radio is connected via Bluetooth to the headset, it could control the PTT

button on the connected radio (note: All communication radios is not supporting this feature).

Streaming A2DP Profile:

A2DP is the profile for streaming audio and AVRCP could control another device which is streaming audio

to the headset e.g. play/pause, next track and previous track.

Ext Audio Input and Output:

It is possible to connect an external radio, phone or music player via the external connector.

Auto shut down:

WS™ LiteCom Pro III has an auto power off function which shuts down the headset if there is no action

(buttons presses or VOX activation) for a certain time. This time is preset to 2 hours but could be changed

by an authorized dealer. Before the headset shuts down there is some warnings beeps and a ghost voice

message, to abort the auto power function just press any button.

Low battery warning and shut down:

When the battery voltage level is getting below a low limit end user will be warned by a ghost voice

message. This message is repeated until the voltage level is below another limit, then the headset is shut

down in a controlled way.

Charging:

Intrinsic safe battery

charger cable should be connected to a wall adapter,

Charging time is approx. 12 h. May not be charged if ambient temperature exceeds 45º C.

Non intrinsic safe battery ACK081 should be charged together with a special charger cable, AL2AI. This

charger cable should be connected to a wall adapter,

Charging time is approx. 3 h, a LED will indicate with green light when the charging is complete. May not

be charged if ambient temperature exceeds 45º C.

ACK081 and
