ADDENDUM

MH-59A8J Remote Microphone

The optional MH-59A8J Remote Microphone provides
control of the major functions of the FT-897 from the
microphone's keypad. The MH-59A8J includes a rotary control
knob for adjust the operating frequency and receiver audio
volume level.

Before connecting the MH-59A8J, you must instruct the
FT-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 to

activate the Menu Mode.

2. Rotate the SELECT knob to recall Menu Mode
No-001 [EXT MENU], then rotate the DIAL to

change the setting to "ON" to enable the extended
Menu Mode.

3. Rotate the SELECT knob to recall Menu Mode
No-059 [MIC SEL]. The default setting for this
Menu is "NOR". Rotate the DIAL to change the
setting to "RMT".

4. Press and hold in the [FUNC] key for one second to
save the new setting and exit to normal operation.

MH-59A8J Switches and Controls

(1) LOCK Switch

Pressing this key locks the FT-897's front panel keys so
as to prevent accidental frequency change.

(2) PTT Switch

Press this switch to transmit, and release it to receive.

(3) Keypad

[1(DSP)] key

Pressing this key provides instant access to Multi
Function Row "p" (MFp), which contains the command
keys for the receiver's Digital Signal Processing System.
This key generates the DTMF "1" tone during
transmission, and frequency entry digit "1" during Direct
Keypad Frequency Entry.

[2(MHz)] key

Pressing this key allows tuning in 1-MHz steps of the
VFO frequency.
This key generates the DTMF "2" tone during
transmission, and frequency entry digit "2" during Direct
Keypad Frequency Entry.

[3(CLAR)] key

Pressing this key momentarily activates the Receiver
Clarifier ("R.I.T.") feature.
Press and hold in this key for one second to activate the
IF Shift feature.
This key generates the DTMF "3" tone during
transmission, and frequency entry digit "3" during Direct
Keypad Frequency Entry.

[4(HOME)] key

Pressing this key recalls a favorite "Home" frequency
memory.
This key generates the DTMF "4" tone during
transmission, and frequency entry digit "4" during Direct
Keypad Frequency Entry.

[5(⇐⇐MODE)] key

Pressing this key changes the operating mode:

USB⇒⇒LSB⇒⇒PKT⇒⇒DIG⇒⇒FM⇒⇒AM⇒⇒CWR⇒⇒CW⇒⇒USB

This key generates the DTMF "5" tone during
transmission, and frequency entry digit "5" during Direct
Keypad Frequency Entry.

[6(MODE⇒⇒)] key

Pressing this key changes the operating mode:

USB⇒⇒CW⇒⇒CWR⇒⇒AM⇒⇒FM⇒⇒DIG⇒⇒PKT⇒⇒LSB⇒⇒USB

[7(V/M)] key

Pressing this key switches frequency control between the
VFO and Memory Systems.
This key generates the DTMF "7" tone during
transmission, and frequency entry digit "7" during Direct
Keypad Frequency Entry.

[8(DWN BAND)] key

Pressing this key causes the frequency to be moved
down by one frequency band:

1.8MHz⇒⇒430MHz⇒⇒144MHz⇒⇒108MHz⇒⇒88MHz⇒⇒

50MHz⇒⇒28MHz⇒⇒24MHz⇒⇒21MHz⇒⇒18MHz⇒⇒15MHz⇒⇒

14MHz⇒⇒10MHz⇒⇒7MHz⇒⇒5MHz⇒⇒3.5MHz⇒⇒1.8MHz

This key generates the DTMF "8" tone during
transmission, and frequency entry digit "8" during Direct
Keypad Frequency Entry.

[9(BAND UP)] key

Pressing this key causes the frequency to be moved up
by one frequency band:

1.8MHz⇒⇒3.5MHz⇒⇒5MHz⇒⇒7MHz⇒⇒10MHz⇒⇒14MHz⇒⇒

15MHz⇒⇒18MHz⇒⇒21MHz⇒⇒24MHz⇒⇒28MHz⇒⇒50MHz⇒⇒
