ART-300М – a number of car user amplifiers, which provide range extension for cordless phones stated in the table.
Amplifier model Cordless phone model
ART-300M2 Senao SN-258
ART-300M PLUS Senao SN-258 PLUS
ART-300М3 SN-358 SmART
Senao SN-358
ART-300М3R Senao SN-358R Ultra
Amplifiers ART-300M are also desined to provide communication range extension in case of use the appropriate models of handsets in controlling and communication system CONNECT-2000.
Use of car amplifiers ART-300M allowes to:
• extend the effective radius of action in 2 – 3 times as compared with a standard version, in case of use together with amplifiers ART-300 or ART-325 to extend the communication range up to 50 km for (ART-300M + ART-300) and up to 70 km for (ART-300M + ART-325);
• reduce the radiation level due to power takeoff in amplifier path HF;
• supply the charge of rechargable battery, also to extend the battery life, avoiding its overdischarge (the charging goes on even during the communication ) or overcharge (automatic check of battery charge).
ART-300M amplifiers: ART-300M amplifiers:
― designed to connect to car imbeded circuit with voltage 12 – 15,6 V and «negative» potential on frame; it is possible to use the amplifier in stationary conditions, using the appropriate power supply;
― have a built-in charging device;
― easy to install in car.
We recommend to use the A2M antenna with ART-300M amplifiers.
ART-300M combines in its structure following components:
• bidirectional high frequency amplifier (HFA), has a display and output power control circuit, antenna tract condition and protection from mulfunction of work;
• built-in charging device with control and battery charge display, imbeded in HFA frame;
• handset holder (for ART-300M2, ART-300M PLUS) for non-invasive connection of HFA.
