This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that
may cause undesired operation.
Your Midland model F-12 brings the new FRS (Family Radio Service) to your
fingertips. The Family Radio Service is provided for by the FCC and is totally license
free. For the first time business and the general public can use the quiet UHF FM band
for personal communications at no charge. The F-12 uses maximum allowable power
for range up to 2 miles. Use for fishing, hunting, picnics, biking, business, or any other
activity where communications are needed for convenience or safety. The model F-12
operates on 14 channels to provide the best in quiet and private communication. Also
this radio offers power save, and auto-squelch.
WARNING
Your wireless hand-held portable transceiver contains a low power
transmitter. When the Push-to-Talk (PTT) button is pressed it sends out
radio frequency (RF) signals. The device is authorized to operate at a
duty factor not to exceed 50%. In August 1996, the Federal
Communications Commission (FCC) adopted RF exposure guidelines
with safety levels for hand-held wireless devices.
To maintain compliance with the FCC's RF exposure guidelines, this transmitter
and its antenna must maintain a separation distance of least 2 inches (5
centimeters) from your face. Speak in a normal voice, with the antenna pointed
up and away from the face at the required separation distance. The belt clip is
for storage purposes only. DO NOT TRANSMIT WHILE USING THE BELT
CLIP. To transmit, hold the device away from your body and ensure the
antenna is at least 2 inches (5 centimeters) from your body when transmitting.
TIPS FOR GETTING THE MOST FROM YOUR F-20
Due to the band of operation (462/467 MHz) the F-12 provides communications that
are virtually free of atmospheric interference (skip) that is common on lower
frequency bands. Along with this and an antenna system that is very efficient as
compared to other unlicensed radio bands, communications range is surprisingly good.
Many times the limits to maximum possible range are environmental factors such as
blockage caused by trees, buildings, hills, or other obstructions. If you find
communication is not possible, many times this can be overcome by moving only a few
feet to a new location. Range may be reduced while operating in a vehicle or from
inside to outside a metal building. Battery condition also affects range. The F-12
operates best on alkaline batteries. While this unit has been designed with gaskets for
water resistance and ruggedness it is a precision piece of electronic equipment that
should not be exposed to water or handled carelessly. Normal care should result in
years of trouble free operation. Do not leave batteries installed over a long period of
time as leakage may occur that can destroy the radio. Always save your receipt, as it is
required for warranty consideration.
A NOTE ABOUT THE CTCSS CODES
This radio incorporates 38 CTCSS (Continuos Tone Coded Squelch System) codes
that, when activated, prevent the user from hearing other radios that do not have the
same code. These codes do not make your conversation private. If you experience
difficulties contacting or hearing other radios in your group make sure the CTCSS
code is set the same on all radios. If you are using the F-12 where interference from
other radios or electrical devices are present, enabling the CTCSS codes will usually
mute the interference. Many times interference will be noticed by the presence of loud
static from the speaker.
PREPARATION
BATTERIES
F-12 radios operate with 3 AAA Alkaline, Ni-Cad (nickel cadmium) or Ni-MH
(nickel metal hydride) batteries (optional). Ni-Cad batteries provide about 7 hours of
use. Alkaline batteries will provide about 20 hours of use and Ni-MH batteries will
provide about 14 hours of use. If the F-12 is supplied with Ni-Cad batteries and a
wall charger, Ni-Cad and Ni-MH batteries must be charged prior to use. Charge NICad batteries at least 10 hours. Charge Ni-MH batteries at least 24 hours. DO NOT
attempt to charge any type of Alkaline batteries in this radio.
To Install Batteries:
Hold the radio face down. Press the latch so it swings away from the cover.
1. Lift the battery cover slightly. Gently slide the cover off the unit.
2. Insert 3 AAA batteries observing the proper polarity.
3. Replace the battery cover over the batteries and fasten with the latch.
Low Battery Indicator:
The battery icon in the lower left of the display will flash when the batteries are in
need of charging.
Instructions for optional charger
Install NI-Cad (nickel cadmium) batteries observing their polarity. Plug the 18-???
charger into any 110/115 V wall socket. Plug the cord into the jack on the side of the
radio under the rubber plug marked “MIC/CHG”. Charge the batteries for at least 10
hours for Ni-Cad and 16 hours for Ni-MH.. When using a drop-in charger (models
18-??? or 18-???) follow the setup instructions then simply set the radio in the charger
stand and observe that the LED on the charger is lit. The radio should be turned off
while charging.
DO NOT attempt to charge any type of Alkaline batteries in this radio.
QUICK USE INSTRUCTIONS:
1.
2.
3.
4.
5.
Install fresh alkaline or fully charged Ni-Cad or Ni-MH batteries.
Turn the unit on by turning the ON/OFF/VOLUME clockwise until a click is
heard.
Use the ON/OFF/VOLUME control to adjust the volume. To test the volume
setting, press and hold the “MON” button so static noise can be heard. The
noise can be used as a reference level for volume setting.
To talk press the PTT (push to talk) button on the left side of the radio and talk
in a normal voice into the front of the radio about three inches away from your
mouth.
To listen release the PTT button.
Operating the Radio
TO OPERATE HANDS FREE VOX
(VOICE OPERATED TRANSMIT)
To get the most use from the “VOX” feature you must first determine what sensitivity
level is needed to activate the “VOX” control. Sensitivity is how loud you have to talk
to activate the “VOX” circuit. The “VOX” has three levels of sensitivity that can be
adjusted. The 1 option you can talk in a normal voice with no background noise to
activate the “VOX” circuit. The option 2 will require more voice level to activate the
“VOX” circuit. This is useful in slightly noisier areas that might activate the “VOX”
without talking. The option 3 will require the most voice level to activate the “VOX”
circuit. This will be useful in very noisy areas. The next adjustment is the delay. This
is a function of the “VOX” that keeps the radio in transmit mode after you stop talking.
A delay that is set to short will cause the “VOX” circuit to stop between some words.
The delay is adjustable to three levels. Level 1 will give about one half second of
delay, level three will give you about one and one half seconds of delay. By activating
the “VOX” you only have to talk into the front of the radio or use a headset to make the
radio transmit. The PTT (push to talk) button is not functional in “VOX” mode. It is
recommended to use a headset when using the “VOX” feature.
NOTE: It is recommended to disable the Roger Beep when VOX is in use. See page 8
for instructions.
Setting VOX Functions.
Setting VOX Levels
1.
With the radio in the off position, press and hold the “CALL” button and turn the
radio on. The display will show “L” followed by a 1, 2 or three depending on
previous settings.
2. Press the channel “UP” or “DOWN” buttons to select the level desired.
! As described earlier L 1 will be the most sensitive and L 3 will be the least
sensitive.
3. Press the “F” button to switch to the Delay setting. A “d” followed by a d1, d2 or
a d3 will show on the display depending on previous settings.
4. Press the channel “UP” or “DOWN” buttons to select the level desired.
! As described earlier d 1 will be the shortest and d 3 will be the longest delay.
5. Press the “ENTER button to store your settings and return to normal operation
mode.
TO ENABLE / DISABLE VOX MODE

FEATURES AND LOCATION OF CONTOLS
TO TURN THE RADIO ON OR OFF
The ON/OFF/VOLUME control at the top of the radio controls power and volume. A
series of tones will be heard confirming that radio is working.
TO CHANGE THE CHANNEL IN USE
Press and release the channel button /\ or \/ to select the desired channel. To change
channel rapidly, press and hold the channel button /\ or \/ until the desired channel
appears on the display.
ACTIVATING SCAN FUNCTIONS
The F-12 has two scan modes. The most popular and most used is the “BUSY”
channel scan. This allows the radio to stop on a channel that someone is talking on.
When the radio stops on a “Busy” channel, the scan will stop and resume after about 5
seconds. The other is “DUAL WATCH”. This allows you to scan only two channels.
This is useful when you want to keep track of two other people.
Busy Channel Scan:
1. Press and release the ”F” button the ”SCAN” icon (5) will begin flashing.
2. Press and release the “UP” or “DOWN” channel button to activate scan. The unit
will now begin scanning through the channels.
! Pressing the “UP” or “DOWN” channel button during scan will determine if
the channels are scanned up or down.
! Pressing the “PTT” (push to talk) button will cause the radio to stop scanning
and return to normal operate mode.
Activating Dual Watch
Dual watch is a function that allows you to scan only two channels.
1. Select channel one.
2. Press the “F” button three times until “DW” (11) is flashing.
3. Select the second channel to be scanned.
! About 1 second after your selection of the second channel is complete the
radio will begin switching between the two channels.
! When the radio hears activity on either channel, scanning will stop on that
channel for about 5 seconds and then resume scanning.
! If communication is desired on the channel scanning stopped on, press the
“PTT” button. This will deactivate Dual Watch and allow you to communicate
normally.
4. To reactivate Dual Watch repeat steps above.
TO USE CALL BUTTON
Press and release the CALL button. A call signal of alternating tones will be sent for
about 2 seconds. Both radios must be on the same channel and the radios must be
turned on.
! If any function is selected and no buttons are pressed in 10 seconds, the
current settings are retained and the radio switches back to normal operation.
TO ENABLE/DISABLE “ROGER-BEEP”
The radio transmits a rapid tone sequence when the PTT button is released if this
feature is active. The default condition is for the “roger beep” to be off.
1. Press the “F” button until you on the display “oF” (depending on previous
programming) with a flashing music note
(8) in the display.
2. Press the channel /\ or \/ buttons to select off or on.
! “oF” is roger beep off. “oN” is roger beep on.
3. Press "ENTER" to store your selection.
TO ENABLE / DISABLE KEY BOARD LOCK
To enable the KEYBOARD LOCK press and hold the “ENTER” button for 2 seconds.
The display will contain a key symbol (9). PTT, MON and CALL buttons will still
be active. The “ENTER” button will also activate the backlight for 5 seconds. When
radio is in lock mode and any other keys are pressed a tone will be heard. To disable
the KEYBOARD LOCK, press and hold the “ENTER” button for about 2 seconds.
POWER SAVE CIRCUIT
This part of the operation of the radio is completely automatic and not adjustable.
When the radio has not transmitted or received a signal for about 8 seconds it will
begin to cycle from a sleep mode to fully on. This occurs several times a minute. If a
signal is received or you cause the unit to transmit the radio will become fully awake.
This cycling from sleep to fully on increases the standby battery life more than 50%.
USING THE MONITOR FUNCTION
1. Press and hold the “MON” button on the side of the radio to open the squelch.
! This allows you to override the squelch and the “CTCSS” tones. This is useful
to monitor the channel before you transmit to ensure there is not someone using
the channel when you have “CTCSS” tones programmed. This is also useful if
you suspect someone in your group does not have the proper “CTCSS” tones
programmed.
2. Release the “MON” button to restore the squelch to normal.
RESETTING THE RADIO
If the radio stops responding to button presses or otherwise does not function properly
in some cases the radio can be reset to restore normal operation.
To reset the radio: With the radio off, press and hold the “F” button and turn the radio
on. Release the “F” button when the radio powers up. (see turning the radio on)
ACTIVATING “PRIVACY” CODES
To activate “CTCSS” codes
! Activating the “CTCSS” code will prevent you from hearing any conversation
that is not using the same “CTCSS” code. This does not make your
conversation private.
1. Press the “F” button twice to cause the icon “CTCSS” to be displayed in the
upper left of the display to flash.
2. Press and release the “UP” or “DOWN” buttons to select the “CTCSS” code you
desire.
3. Press “ENTER” to store the code setting for that channel.
! A code of “oF” means no code is programmed.
! You must do this for each of the channels you want CTCSS codes on.
! Activating the “CTCSS” code will prevent you from hearing any conversation
that is not using the same “CTCSS” code. This does not make your
conversation private.
4. If you wish to set another channel for CTCSS code, choose a different code than
the ones in use.
The following is a list of frequencies of the CTCSS codes. Different brands of radios
may use a different number code for the frequencies. For operation with other brands
of radios the selected CTCSS frequency must match.
01=67.0 Hz 11=97.4 Hz
21=136.5 Hz
31=192.8 Hz
02=71.9 Hz 12=100.0 Hz

TROUBLESHOOTING
PROBLEM
No Power
Cannot receive messages
Range is short
Radio squeals when
receivnng messages
Messages not transmitted.
Interference/Static
Cannot change channels
Battery icon flashes
Display is dim
SOLUTION
1. Check battery installation and/or replace batteries
1. Make sure the volume is set high enough.
2. Change your location, you may be out of range.
3. Disable CTCSS code. Make sure all parties are
using the same code.
4. Install batteries properly or replace.
1. Operating the radio in a vehicle or metal building
will decrease the range. If possible operate outside of
vehicles or buildings.
2. Carrying the radio so that the antenna is very near
the body will decrease the range. Hold the radio in the
open for the best range.
3. Battery condition can affect range. Replace or
recharge batteries.
1. Check battery condition.
Usually lowering the
volume stops the squealing. This indicates weak
batteries.
1. If PTT button is not responding, check to see if
VOX is active.
2. If VOX is in use, check for correct VOX level
setting.
1. Change your location. The interference may be
caused by nearby electronic or electrical equipment.
1. Make sure keyboard is not locked.
2. Make sure the radio is not transmitting.
1. Replace alkaline batteries or recharge rechargeable
batteries.
Reposition or replace batteries.

CARE OF RECHARGEABLE NI-CAD AND NI-MH BATTERIES
ALWAYS DISPOSE OF BATTERIES PROPERLY
Always follow the battery manufacturer's recommendations for charging and disposing
of Ni-Cad and Ni-MH batteries.
The following is meant as general information regarding Ni-Cad/Ni-MH batteries.
1. Occasionally allow the batteries to fully discharge before recharging. Full
discharge will be indicated by the low battery indicator coming on during receive
operation.
2. Always allow the battery to fully charge before using. This requires 10 hours with
the approved charger. (Ni-MH batteries require 16 hours for full charge.)
3. The above will prevent the batteries from developing “memory” which effectively
reduces their capacity.
4. It is better to store Ni-Cad batteries that are discharged rather than charged.
Ni-MH batteries are best stored charged.
