Description

2.1

General

The headset is a transmitter/receiver for wireless duplex communication between a max. of five

communication parties over short distances. The range depends on the local circumstances. Up to four

standard headsets are allocated to a base headset. Channel selection is effected automatically by the

headsets. High protection against eavesdropping and interferences is ensured.

The headset protects against harmful ambient noise and allows communication in noisy environments.

The headset microphone is noise-compensating and is equipped with a windshield and a flexible

gooseneck.

The minimum version of the system comprises one base headset and one standard headset. Up to four

standard headsets can be operated in conjunction with the base headset.

Base and standard headsets are marked by an imprint on the left headset muff, as follows:

– CT-DECT Headset Base

– CT-DECT Headset Standard

2.2

Usage within a CT-DECT system

In a CT-DECT system instead of the base headset for example the base station »CT-DECT

Conference«, »CT-DECT Case« or the table top device »CT-DECT Station« is used. Notice the special

CeoTronics operating instructions for these devices.

2.3

Usage within a CT-DECT GateCom system

In a CT-DECT GateCom system instead of the base headset a CT-DECT GateCom Interface Case or a

CT-DECT GateCom Compact is used that usually resides in a weatherproof carrying bag. Notice the

special CeoTronics operating instructions for these devices.

2.4

Power supply and operating time

Power for the headset is supplied by a 3.6 V/2300 mAh NiMH rechargeable battery or an optional

3.6 V/2300 mAh Li-Ion rechargeable battery in the right headset muff. With fully charged battery the

operating time for continuous operation is approx. 20 hours.

2.5

Audio signals used

Two different tones are used for signalling the operating status. The tone for the indication of a positive

operating status has a higher frequency than the tone for the indication of a negative operating status.

Signalling of the various operating status is effected by a varying number of consecutive high tones or

low tones.

Positive acknowledgement tone

All positive operating status are indicated by a high tone.

Negative acknowledgement tone and error tone

All negative operating status and error status are indicated by a low tone.

2.6

Sidetone

The sidetone while speaking is audible in the headsets only after connection setup between the

headsets. Due to this a control is always available as to whether a connection is active or not.

In the case of the CT-DECT GateCom system there is a sidetone audible in the headsets, when a

connection to the aircraft-interface is active.
