Linear Amplifier ControlThe external control relay is not activated at the fac-tory so that the operation of the radio will remain atthe lowest mechanical noise level during CW Fullbreak-in operations. If the use of this control relay isrequired, such as for use with an external linearamplifier it may be activated with the following pro-cedure.1.Remove the top and bottom covers of thetransceiver. Refer to Sections 6-6-1 and 6-6-2.2. Set the slide switch (S1) on the signal unit to ONas shown in the accompanying diagram.34sensitivity leve12voltsatapproximately10mA maximumisavailableatpinnumber7oftheREMOTEconnectorforcontrolofanexternalkeyingrelay,ifnecessary.Werecommendthe useofa7pinDINplugforthisconnection.WhenoperationofthistransceiverwiththeTL-922/922Aisanticipatedyoushouldusethecontrolcablesupplied withthelinearamplifier.Note:The TL-922/922A is NOT designed for Full Break-inoperation.
