When this goes out or the “bat low”warning appears on the display, switch it off, plug one endof the charger into the mains, the other end into theAR9ooUK charger socket marked “CHG DC6V”, andcharge for 8-10 hours. The reason for this procedure is that Nickel Cadmium (NiCad) batteries may acquire what hasbeen described as a “memory” which subsequently gives riseto difficulty in charging them fully. This fulldischarge/charge cycle at the outset minimises this problemand ensures that optimum battery usage is achieved. Notethat during the initial discharge you can use the ARQOOUICbut it will, in all probability soon start to die on you as thebattery gets flatter and flatter. The same thing applies to theinitial charge - it will take several minutes to start coming tolife again, but after that there is no reason why you should notuse it, but I would be inclined to leave the dial light 017'. Oneother thing to remember - if you use the AR9ooUK duringthe charging cycle, then the charging time should beincreased to compensate. As overcharging: is not undulyharmful it is not necessary to set the alarm for 3 am. toswitch the charger off - up to 16 hours once in a while willnot hurt. Repeating this rapid discharge/full charge cyclethree or four times is not a bad idea and results in theNiCads reaching their full capacity of 7 to 9 hours normalusage. Subsequently, an overnight charge or a charge whileyou are at work when the low battery (Bat-Low) warningappears on the display is all that is necessary. As for thetotal life of the NiCads - hard to say o depends not only onusage but many other factors, but I would be a bitdisappointed if they only lasted a year and delighted if theylasted four. Fortunately they do not cost the earth toreplace. ==Operating modes== The AR9ooUK can be used in three different ways.In the MANUAL mode, any frequency within the tuningrange may be entered into any of the 100 memory channels(Ao1 to E20) and,recalled by entering the appropriatechannel number. Additionally, repeated pressing ofMANUAL goes through the memories sequentially, tuningto the different frequencies in them. The second mode of
