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 (voi ce operated transmit) that all ows 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 pr ovides communications that are virtually free of atmospheric interference (skip) that is common on lower
3
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 ot her obs tr uct io ns. If you find c ommunic at io n i s no t po s si bl e , many t ime s t his ca n 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 radi o. If you experience problems operating the radio, turn off the radio, press and hold the to the factory settings.
consideration.
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, t he Federal Communications Commission (FCC) adopted RF exposure guidelines with safety levels for hand­held wir e le s s d evice s .

WARNING
To maintain comp liance with t he FCC' s RF e xpos ure 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) fr om 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
4
from hearing other radi os that do not have the same code. These codes your conversation private. If you experience difficulties contacting or hearing other radios in your group make sure the If you are using the P20 where interference from other radios or electrical devices are present, enabling the times interference will be noticed by the presence of loud static from the speaker.
BATTERIES
P20 radios oper ate 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.

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 Page 6 illustration) on the bottom of the radio.

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 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.
