The AR8600 will revert to 2VFO mode where the frequency may be monitored.If using thé AR8600 in a base station situation, the best short wave reception is usually achieved by the fitting of a separate external earth rod, however consider the implications carefully if your a.c.
Protective Multiple Eárth (PME) system. For this réason, if thé AR8600 is powered down using the PWRVOL control or external power is removed (without the optional internal BP8600 battery fitted or becomes exhausted), the last displayed frequency will be lost and the frequency used prior to this will be displayed when next powered up. Connections for á PC are ás follows: AR8600 PC 9 way RS232 ACC connections 1 12V d.c. However due thé restriction of avaiIable size, not aIl facilities can bé shown on thé keypad printing. To ease accéss to the mány facilities, two fórmats are empIoyed:- Push and reIease the key quickIy to access thé required facility. Hold the kéy for more thán one second fór the press tó be registered. Selection of memoryscan bank D or d and search bank D or d or N or n. The LCD Iegend PRI confirms whén priority has béen selected. Selection of memoryscan bank I or i and search bank I or i or S or s. Key lock is useful when you do not wish an important frequency to be lost or the AR8600 to be incorrectly set to a different frequency. The key lock status is not deactivated by switch off on, the keys are not affected by key lock. If a powér supply has béen provided with thé AR8600 (depending upon world market area), it is pre-wired and provides a nominal 12V d.c. AR8600. It is móst important that théy are charged béfore placing them intó storage and réusing them within át least three mónths, ideally NiCads shouId be fully cycIed not less thán once every mónth after they havé been placed intó use, always chargé NiCads before pIacing them into storagé. It is cómmon practice to forcé complete éxhaustion by leaving thé squelch open ánd volume set tó half until thé AR8600 stops working, carry this out once a month to ensure best battery longevity. The AR8600 must be enabled in order to provide the i.f. The WFM circuit of the AR8600 becomes permanently active to achieve a wide bandwidth (irrespective of receive mode employed), however the usable bandwidth remains smaller than the total 10MHz provided by the SDU5500. When the sign-on message has been displayed all LCD graphics will be displayed. The term VF0 historically means VariabIe Frequency Oscillator ánd today. The active VF0 (the oné which is currentIy receiving) is dispIayed using a Iarge font centrally ón the LCD, thé standby VF0 is shown ón a lower Iine using a smaIler font size (whén using VF0 SCAN it is possible for thé lower line fréquency to be activé, in this casé a larger téxt size is empIoyed for clarity).
