The minimum version of the system comprises one base unit and one standard unit. A second standard

unit can also be operated in conjunction with the base unit. The base and standard units are marked by

an imprint, as follows:

– CT-DECT Base

– CT-DECT Standard

NOTE

The base unit and the standard unit(s) can also be used in conjunction with other CeoTronics

DECT units and DECT systems. Notice the special CeoTronics operating instructions for these

units and systems.

2.2

Power supply and operating time

Power is supplied by a 3.6 V/2300 mAh Li-Ion rechargeable battery in the battery compartment of the

unit. With a fully charged battery the operating time for continuous operation is approx. 20 hours.

2.3

Audio signals used

Two different audible tones are used for signalling the operating status via the communication set

connected to the unit. The tone for the indication of positive responses (P-tone) has a higher frequency

than the tone for the indication of negative responses (N-tone). Signalling of the various events is

effected by a varying number of consecutive P-tones or N-tones.

Positive acknowledgement tone

All positive responses are indicated by a high P-tone.

Negative acknowledgement tone and error tone

All negative responses and error status are indicated by a low N-tone.

Battery warning

If the battery has an undervoltage a low 3-beep N-tone sequence »N-N-N« sounds approximately every

10 seconds.

Range warning

If the range limit is reached, a high 3-beep P-tone sequence »P-P-P« sounds approx. every 5 seconds.

Unit with hand microphone SM 3

The hand microphone SM 3 (for example see Fig. 2) consists of a PTT button (Fig. 2/a), loudspeaker

(b), microphone (c), and connection cable with plug (e) for connection to the transmitter/receiver unit.

An earphone can be connected to the 3.5 mm (d) jack. The hand microphone can be fastened to a

suitable place on the clothing by means of the fastening clip on the rear. The best distance for speaking

into the microphone is approx. 10 cm (approx. 4 in.).

Unit with HeavyDuty Headset with level limited ambient sound reception

The HeavyDuty Headset with level limited ambient sound reception (for example see Fig. 3) protects

against harmful ambient noise. It might be equipped as follows: adjustable headband (Fig. 3/a), one

speaker for radio reception in the right-hand and in the left-hand ear muff (b) respectively, noise

cancelling microphone with windshield (e) and flexible goose neck (d), without or with PTT button (f),

connecting cable and plug (g) for connection to the unit.

HeavyDuty Headsets with level limited ambient sound reception are used mainly where ambient

sounds, warning signals etc. have to be heard alongside duplex communication. The external sounds

are received by the microphone (c) on the front side of the left-hand headset muff and are audible

inside this headset muff via the ambient sound speaker. If the external sounds exceed 85 dB(A), the

sound level emitted to the ear by the ambient sound speaker is limited electronically to a maximum of

85 dB(A).
