The following information describes the configuration and operation of the Icom F3 radios provided by David Kovar to various teams. If you have any questions about, or corrections to, this document, please send mail to kovar@1srg.org.
I have included the full information on all of the frequencies in these radios. All of this information is available from a variety of resources dedicated to scanning hobby. I felt that it was more important to fully inform the users of the radio than it was to attempt to hide information which is readily available elsewhere.
1.
Knob
near the antenna turns clockwise to turn the radio on. Continue clockwise increases
volume, counterclockwise decreases volume.
2.
The radio
has 2 banks of 16 each channels to choose from. When the radio is turned on,
it will return to the channel last used, unless the battery has been changed.
Not all channels are necessarily programmed.
3. The
Quick Charger Drop-in Base is for charging the Ni-Cad battery ONLY.
The battery must be attached to the radio in order to be held in the correct
position for charging. There is a “Wall Wart” power supply which attaches
to the base and plugs into a wall outlet. There is also a cord with a cigarette
lighter plug. This can be attached to the base in place of the wall wart to
allow charging from a car. Be careful with this. Some cars require the key to
be turned on to get power to the cigarette lighter, so this should only be done
when the engine is runnung.
4. The
Alkaline Battery Pack holds 8 size AA batteries. These can NOT
be recharged. When this pack runs down, the individual AA batteries should
be removed and replaced.

IC-F3 can be Field Programmed. IC-F3S can not.
The following is the standard programming I used for the radios (DCK-4). Your milage may vary, as they say.

I would caution you against casually reprogramming your radio unless a) you know what you're doing and b) you document the change in some manner. It is very frustrating to try to troubleshoot someone's radio in the field, expecting one configuration and then finding out that they modified it slightly and that is the source of your problem.
1.
While
pushing <C> and <speaker symbol>, turn power ON.
2.
“DEALR”
appears on LCD.
3.
Input
Dealer Passcode.
4.
Frequency
that is now set up appears on LCD. (Receive Frequency).
5.
Push
<up triangle> or <down triangle> to select a channel, then input
frequency with 10-keypad.
6.
<speaker
symbol> will cancel input.
7.
<#>
will inhibit the frequency.
8.
Push
<left triangle> to shift to Transmit Frequency, then input frequency with
10-keypad.
9.
Repeat
step 5 for additional channels.
10.
Turn
power OFF
11.
Turn
power ON as normal to operate with new frequencies.
Note:
In this Dealer Set Mode, it is possible to program only the Transmit and Receive
Frequency
You can reset the tones for the current frequency via the keypad. Select the frequency you want to modify and then press P2 (Rev1) or B (Rev 2) to get to the C Tone CH Enter mode. Use the up/down arrows to select one of mR, 1 - 9 for your current tone. Hit P2/B again to return to normal operation. I do not know if this change persists after changing frequencies or after turning the radio on or off.
The pre-configured tones are:
| mR | unknown (null?) |
| 1 | null |
| 2 | 82.5 |
| 3 | 97.4 |
| 4 | 110.9 |
| 5 | 146.2 |
| 6 | 167.9 |
| 7 | 123.0 |
| 8 | 131.8 |
| 9 | 103.5 |
