Kompernass KH 2356 manual Introduction, Charging the battery

Introduction

Bluetooth is a wireless communication system with a short range. It makes possible wireless connections between Bluetooth devices such as, for example, mobile telephones, PDA and PCs. Bluetooth relates itself to a worldwide standard for operation in the internationally recognised ISM Frequency Range (Industrial, Scientific and Medical). Within the ISM Frequency Range (2,402 - 2,480 GHz), a data transfer range of approx. 10 Meters (Class II) is achieved. The disturbance susceptibility through other users of the ISM Frequency range, such as for example microwaves, WLAN (802.116) or garage door openers, is minimized by so-called "Frequency-Hopping". With Frequency hopping, a change of frequency levels takes place at up to 1600 times per second, thereby Bluetooth is also considerd to be relatively tap proof.

Charging the battery

You can charge the headset via the power supply unit or the vehicle adapter.

Attention!

Only charge the headset with the supplied power supply unit and/or the supplied vehicle adapter.

Do not use any other charging device or power supply unit! Only connect the vehicle adapter to a cigarrette lighter socket (In vehicle receptical) with a 12 V or 24 V supply.

The headset is equipped with a rechargeable Lithium Ion battery. Before initial operation this must be fully charged, approx. 2 hours. A fully loaded battery will provide power for a speaking duration of 8 hours and for Standby mode approx. 200 hours.
