The following are the TH-F6A keys and a short description of what they do.

Holding HT in hand along left side are three buttons. Top is PTT button,
1 - Top is PTT button
2 - Middle lamp button (AID FOR VISUALLY-ENABLED)
3- MONI is the bottom button.

Looking at front of handheld, with keypad facing you, the top button,
beneath the visual display, is Multi-scroll [MNU] key explanation
follows. The multi-scroll key [MNU] is used to select menu mode by
pressing it in the middle. It then selects the last menu used. Selection
of menus can also be done by turning tuning knob (default at menu 1 Scan
Resume). To do this press the center of the [MNU] key twice. Default beep
is the low beep. Middle part of this key is also called MNU button. Moving
this key to the right [>] is usually an OK to do something and to the left
[<] is used as an escape ESC or cancel. It also does up or down function.
([U] or [D])

Below the Multi-scroll button is the [@] Power button. Holding it for 1
second turns HT on. Two high beeps indicate the HT is turning on. When the
HT is on, holding [@] Power button down for 1 second turns the HT off. Two
low beeps indicates HT is turning off.

The bottom four rows are a 16-button keypad which is from left to right

1 2 3 A (Top row)
4 5 6 B (Second row)
7 8 9 C (Third row)
* 0 # D (Fourth row)

The arrangement resembles a telephone keypad with A B C D keys to the right
of the corresponding 3 6 9 and # keys. When PTT is held and these keys are
depressed they generate DTMF tones which are transmitted.

When the radio beeps low it usually signifies its default state.

When the keys are used by themselves they do a variety of things. I'll put
the key number in () (AS ON TELEPHONE DTMF KEYPAD) then [name of the key as
in the instruction manual and printed on key]. Example (1) [LOW]

(1) [LOW] \High, Low, E-Low \ TX Power selection default (low-pitched beep)

band starts out at AM, HF, 6m, FM, Air Band, 2m, VHF TV, 1.25m (220), 70cm
(440), UHF TV, 23cm. The default is at 2m when in A band, and 440 when in
B band.

(3) [A/B] \ Toggles A band and B band. A default.

(A) [F] \ Function button, hitting this key momentarily before hitting
another key activates second function of keys. If depressed for 1 second
activates keypad lock. Default unlocked.
(4) [INFO] \ Selects the info band frequencies which are the ten weather
freq by default. To exit this press [MR] or [VFO], pressing [A/B] will not
exit this function.

(5) [SQL] \ Squelch When selected, squelch can be changed by rotating tuning
knob. Pressing (5) again after changing squelch level stores the changed
level. If no change press ESC [<]. Pressing [MNU] or Multi-scroll Right [>]
stores setting also.

(6) [BAL] \ A/B volume balance default balanced. Tuning knob changes balance.

(B) [VFO] \ VFO selection key

(7) [TONE] \ Tone selection key. Order tone on, ctcss, dcs, no tone default
