2. FUNC Keys
These three keys select many of the most important operating features of the transceiver. When you press the [F] key,
then rotate the MEM/VFO CH knob, the current function of that key will appear above each of the [A], [B], and [C]
keys (along the bottom of the LCD). You may scroll the display through 17 rows of functions available for use via the
[A], [B], and [C] keys.
The available features are shown in page 14.
3. MIC Jack
Connect the supplied MH-31B8 Hand Microphone to this jack.
4. PHONES Jack
This 1/4-inch, 3-contact jack accepts either monaural or stereo headphones with 2- or 3-contact plugs. When a plug is
inserted, the loudspeaker is disabled. The audio level varies according to the setting of the front panel’s AF knob.
5. POWER Switch
Press and hold in the POWER switch for one second to turn to the transceiver on or off.
6. [F] Key
Press this key momentarily to enable the changing of the function of the Multi Function keys ([A], [B],

Press and hold this key for one second to activate the “Menu” mode.
7. LOCK Key
Pressing this key locks the front panel keys so as to prevent accidental frequency change. The LOCK key itself,

This is the main tuning dial for the transceiver. It is used both for frequency tuning as well as “Menu” setting in the
transceiver.
9. AF Knob
The (inner) VOL knob adjusts the receiver audio volume level presented to the internal or external
speaker. Clockwise rotation increases the volume level.

Mode No-080 [SQL/RF GAIN], this control may be changed to function as a Squelch control, which may be used to
silence background noise when no signal is present. In the other versions, its default setting is set to “Squelch.”
