THIS RADIO COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS
SUBJECT TO THE CONDITION THAT THIS DEVICE DOES NOT CAUSE
HARMFUL INTERFERENCE.
Your Midland model P20 UHF FM business two-way radio is designed to provide
you with line-of-sight communications for a range up to 4 miles. The model P20
incorporates channels with 38 different CTCSS and 83 DCS codes to provide the best
in quiet communications. Also this radio offers scan, power save, 9 memory channels
and a multifunction back-lighted liquid crystal display. This unit also incorporates
VOX (voice operated transmit) that allows hands free use when the radio is equipped
with certain accessories.
TIPS FOR GETTING THE MOST FROM YOUR P20
Due to the band of operation (464/467/469 MHz) the P20 provides communications
that are virtually free of atmospheric interference (skip) that is common on lower
4
frequency bands. Along with this and an antenna system that is very efficient,
communications range is surprisingly good. Many times the limit to maximum possible
range is 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 is greatly reduced while
operating from a metal building or from a vehicle. Battery condition also affects range.
The P20 operates on rechargeable Ni-Cad batteries or 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. If you experience problems operating the radio, turn off the radio,
press and hold the “F” button and turn on the radio. This will cause the radio to return
to the factory settings. Always save your receipt, as it is required for warranty
consideration.
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.
A NOTE ABOUT THE CTCSS or DCS CODES
This radio incorporates 38 CTCSS (Continuos Tone Coded Squelch System) codes
and 83 DCS (Digital Coded Squelch) codes that, when activated, prevent the user
5
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 or DCS code is set the same on all radios.
If you are using the P20 where interference from other radios or electrical devices are
present, enabling the CTCSS or DCS codes will usually mute the interference. Many
times interference will be noticed by the presence of loud static from the speaker.
PREPARATION
BATTERIES
P20 radios operate with 3 AA Alkaline, Ni-Cad (nickel cadmium) or Ni-MH (nickel
metal hydride) batteries (optional). Ni-Cad batteries provide about 15 hours of use.
Alkaline batteries will provide about 45 hours of use and Ni-MH batteries will
provide about 24 hours of use. The P20 may be supplied with Ni-Cad or NI-MH
batteries and a wall charger. Ni-Cad and Ni-MH batteries must be charged prior to
use. Charge at least 10 hours with the standard charger. If you are using Ni-MH
batteries charge at least 16 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 AA batteries observing the proper polarity.
3. Replace the battery cover over the batteries and fasten with the latch.
Battery Indicator:
The battery Condition indicator in the display will show the amount of charge of your
batteries. Replace alkaline or recharge the Ni-Cad batteries as soon as possible after
the indicator shows 2 segments or less of the battery lit.
CHARGING THE BATTERIES
Your P20 may not include rechargeable batteries and a charger. Install the batteries
observing their polarity. If you are using rechargeable batteries and the Midland
standard charger (model 18-396), plug the charger into a 115 volt wall socket and the
charger plug into the charge jack under the cover marked “CHG” ( item 7on
Page 6 illustration) on the bottom of the radio. Allow the batteries to charge 10 hours
for Ni-Cad and 16 hours for Ni-MH prior to use. Never attempt to charge any type
of Alkaline battery in this radio. When using a drop-in charger (models 18-383 or
18-385) 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.
6
BELT CLIP
The P20 comes standard with a belt clip. Attach it to the radio back by sliding the top
of the clip up over the two rectangular bosses on the back of the radio until it snaps
into place. To detach the belt clip, press the lever inside the top of the clip away from
the radio body and slide the clip toward the bottom of the radio.
!
!!
! The belt clip is intended for storage of the radio only (waiting for a call). Do not
transmit the radio while attached to your belt. (see warning on page 4)
QUICK USE INSTRUCTIONS:
Install fresh Alkaline or fully charged Ni-Cad or Ni-MH batteries.
Turn the unit on by rotating the ON/OFF Volume control clockwise.
The squelch is factory set and is not adjustable.
Make sure the radio you want to talk to does not have the CTCSS or other codes
turned on.
To talk, press and hold the “PTT” (Push to Talk) button on the side of the radio
marked “PTT”. Talk into the front of the radio about 6 inches from your mouth.
To listen release the “PTT” button.
" Other functions will be described later.
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 several 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 radio to transmit, the radio will become fully on.
This cycling from sleep to fully on increases the battery life more than 50%. An icon
in the upper right of the display flashing “SAVE” will verify this.
RANGE OF UHF RADIOS
The best range between portable UHF radios is achieved when they are operating in
open terrain outside of buildings and vehicles. Anyone using a portable unit inside a
vehicle will experience a significant loss of range.

OPERATING THE 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 6 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 higher level numbers will require increasing voice
level to activate the “VOX” circuit. This is useful in noisier areas that might activate
the “VOX” without talking. 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 6 levels. Level 1, the shortest will give about one half second of delay.
Increasing the delay value extends the transmitter time to two seconds or more. 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.

TROUBLESHOOTING
PROBLEM SOLUTION
No Power 1. Check battery installation and/or replace batteries
Cannot Receive Messages 1. Make sure the volume is set high enough.
2. Confirm the radios have the same channel and or
CTCSS/DCS code settings.
3. Change your location, you may be out of range.
4. Install batteries properly or replace.
5. Buildings, obstructions, operating indoors or in
vehicles may interfere with communication.
Change your location.
6. Make sure the radio is not transmitting. This could
be due to the radio being switched to VOX
operation or accessories not set properly.
Range is Short 1. Operating the radio from a vehicle or from a 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.
Interference/Static 1. Using the CTCSS should stop you from hearing
interference from other users and computers.
2. Radios too close. Radios must be at least 5 feet
apart.
3. Radios too far apart. Obstacles interfere with
transmissions. Talk range is up to 4 miles in
unobstructed, clear areas.
Radio is not responding to
button presses 1. Make sure radio is not in “VOX” mode.
2. Make sure key lock is not on. See To lock the
controls
3. Make sure radio is not transmitting.
4. Radio might need to be reset, See Resetting Radio.
5. Ensure accessory microphone is set properly (see
Page 12).
Display is dim 1. Reposition or replace batteries.
18
Charger not functioning 1. Charger pin is not properly in place. Check that
charger is fully inserted into the jack on the
bottom of the radio. If using the drop-in charger,
check the contacts on the bottom of the radio they
may require cleaning. If all is correct allow the
batteries to charge for the specified time.
2. Ensure the outlet the charger is plugged into is
functioning properly.
3. Check that the batteries are installed in the radio
properly.
4. Remove batteries from the radio and try to charge
separately.
CARE OF RECHARGEABLE NI-CAD BATTERIES
ALWAYS DISPOSE OF BATTERIES PROPERLY
Always follow the battery manufactures recommendations for
Charging and disposing of Ni-cad batteries.
The following is meant as general information regarding Ni-cad batteries.
1. Occasionally allow the batteries to fully discharge before recharging. The battery
indicator showing less than two segments will indicate full discharge.
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.
Note: Do not charge any type of alkaline batteries in this unit.
