CARE OF OPTIONAL RECHARGEABLE NI-CD BATTERIESIDLANDThe following is meant as general infommation regarding Ni-Cd batteries.Always allow the battery to fully charge befor using.Allow the batteries to fully discharge before recharging.Full discharge will beindecated by the "BATT/LOW indicator.The above will prevent the batteries from developing 'memory which effectivelyreduces their capacity.It is better to store Ni-Cd batteries that are discharged rather than charged.Never use batteries which differ from the ones recommended.Do not mix old andnew batteries or batteries of different capacities.0If you experience problems when using the transceiver,check the following:A.Batteries must be in good condition;The volume level and the squelch control setting:C.The channel selector for an active channelDThe antenna must be properly inserted.CONTROLS AND INDICATORSRM1810USER'S MANUAL75-785Downloaded from www.cbradio.nl1.Antenna connector:with BNC connector type.To obtain better results,use either aMIDLAND 75-785telescopic or an extemal antenna.40 CH AM HANDHELD CB TRANSCEIVER2.Squelch knop:for the maximum receiver sensivity.the control must be regulatedexactly where the receiver background noise disappears.3.On/Off Volume control.In 'OFF'position your transceiver is off.Turn this control75-785 represents the state-of-the art in high-tech engineering.Designed for 40clockwise to switch on the unit.Turn the knop clockwise a litter more to set the audio level.channels Citizen Band Mobile operate,this transceiver is big in performance.The unit.until you get a comfortable reception.useable both in peofessional purposes and private situations such as leisure actvites,is a4.Display:Indicates the selected channel (from 1 to 40).The display tums off when thequalty piece of electronic equipment skilfully constructed from the finest compnents.Thesquelch is operative.circuitry is all a solid-state,mounted on rugged printed circuit boards.It is designed for many5."BATT LOW"LED:This indicator lights when the batteries are low.Replace theyears of reliable,trouble-free performance.Your mobile CB has a built 40 channel Phasealkaline or recharge the AA Ni-Cd batteries.Locked Loop synthesizer circuit.The PLL circuit achieves a new technique for generating all6."TX"LED:The indicator lights when the unit is transmitting.the required frequencies with fewer crystals.The result is much tighter frequency control and7.Speakersuperor reliability.8.Microphone:during transmission,keep your month 4 cm far from the unit,and speakwith a normal tone of voice to the microphone.Main features:9.Push to talk button ("PTT"):By pressing it the transmitter is activated.Whenreleased,you activate the receiver.Condensor microphone.10."Channel UP"button:To skip to the next channel.Keeping this button pressed,theCeramic filter.delive rs greater selectivity and reduces adjacent channel interference."autorepeat"function is obtained.AGC (automatic gain control)for a constant sound level11."Channel DOWN"b
