4. each other can maintain radio contact over a distance of up to 1 5 km Connections Accessories On its upper side your Sporty contains connection sockets for an external microphone 2 5 mm and earphones 3 5 mm You can connect various earphone microphone sets also with vox control available as optional accessories Using an earphone microphone combination you would have both hands free for your hobby Your Albrecht dealer supplies you with the suitable accessories for each application By the way The circuitry of the 2 5 mm microphone socket corresponds to the common amateur radio standard Actually what is an LPD mini transceiver The abbreviation LPD is derived from the term Low Power Device referring to radio systems with a low transmit power level of 10 mW These units can be used by anyone without license or charges payable These radio units operate in the 70 cm UHF range from 433 075 to 434 775 MHz The transmission method is frequency modulation FM This range is primarily allocated to amateur radio however LPD users may also use this frequency range It should be no problem to find an undistorted channel with an overall number of 69 channels selectable By the way the Sporty is type approved in accordance with the European Standard ETS 300 220 complies with EEC directive 89 336 EEC and carries CE number and approval Does the transmit power level cause any harm According to the most recent information 10 mW units
5. in Again the key symbol is displayed Automatic scanning The automatic scanning function is useful when looking for a free radio channel or when simply scanning the entire frequency range for ongoing radio calls Pressing the Up gt or Down button for short period switches to the next higher and lower channel respectively Pressing the button a little bit longer initializes a further beep tone Releasing the button now switches on automatic scanning Scanning is stopped either automatically by a receive signal or manually pressing any key If scanning stops on an occupied channel you can monitor the radio communication for approximately 8 seconds then the scanning function is started again Quick channel selection Keeping the buttons Up gt or Down 7 continuously pressed starts a process of quick channel change Once you have found the channel selected simply release the button Squelch monitor The squelch feature of this unit suppresses undesired basic noise in a free radio channel Signals with a very low level may require noise cancellation to be deactivated For this purpose press the Monitor button during reception and keep it pressed as long as necessary Squelch programming You can also program the trigger point of the squelch function to change the factory setting Unlock the keyboard as described in the section Automatic keyboard locking Then press the Monitor button The display now shows the
