ADDENDUMMH-59A8J Remote MicrophoneThe optional MH-59A8J Remote Microphone providescontrol of the major functions of the FT-897 from themicrophone's keypad. The MH-59A8J includes a rotary controlknob for adjust the operating frequency and receiver audiovolume level.Before connecting the MH-59A8J, you must instruct theFT-897's microprocessor that the MH-59A8J is being used,using the Menu Mode:1. Press and hold in the [FUNC] key for one second toactivate the Menu Mode.2. Rotate the SELECT knob to recall Menu ModeNo-001 [EXT MENU], then rotate the DIAL tochange the setting to "ON" to enable the extendedMenu Mode.3. Rotate the SELECT knob to recall Menu ModeNo-059 [MIC SEL]. The default setting for thisMenu is "NOR". Rotate the DIAL to change thesetting to "RMT".4. Press and hold in the [FUNC] key for one second tosave the new setting and exit to normal operation.MH-59A8J Switches and Controls(1) LOCK SwitchPressing this key locks the FT-897's front panel keys soas to prevent accidental frequency change.FT-897 OPERATING MANUAL(2) PTT SwitchPress this switch to transmit, and release it to receive.(3) Keypad[1(DSP)] keyPressing this key provides instant access to MultiFunction Row "p" (MFp), which contains the commandkeys for the receiver's Digital Signal Processing System.This key generates the DTMF "1" tone duringtransmission, and frequency entry digit "1" during DirectKeypad Frequency Entry.[2(MHz)] keyPressing this key allows tuning in 1-MHz steps of theVFO frequency.This key generates the DTMF "2" tone duringtransmission, and frequency entry digit "2" during DirectKeypad Frequency Entry.[3(CLAR)] keyPressing this key momentarily activates the ReceiverClarifier ("R.I.T.") feature.Press and hold in this key for one second to activate theIF Shift feature.This key generates the DTMF "3" tone duringtransmission, and frequency entry digit "3" during DirectKeypad Frequency Entry.[4(HOME)] keyPressing this key recalls a favorite "Home" frequencymemory.This key generates the DTMF "4" tone duringtransmission, and frequency entry digit "4" during DirectKeypad Frequency Entry.[5(⇐⇐MODE)] keyPressing this key changes the operating mode:USB⇒⇒LSB⇒⇒PKT⇒⇒DIG⇒⇒FM⇒⇒AM⇒⇒CWR⇒⇒CW⇒⇒USBThis key generates the DTMF "5" tone duringtransmission, and frequency entry digit "5" during DirectKeypad Frequency Entry.[6(MODE⇒⇒)] keyPressing this key changes the operating mode:USB⇒⇒CW⇒⇒CWR⇒⇒AM⇒⇒FM⇒⇒DIG⇒⇒PKT⇒⇒LSB⇒⇒USBThis key generates the DTMF "6" tone duringtransmission, and frequency entry digit "6" during DirectKeypad Frequency Entry.Page 69
