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 75-509 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 75-509 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 75-509 operates on 14 channels to provide the best in quiet and private
communication. Also this radio offers power save, and auto-squelch.
TIPS FOR GETTING THE MOST FROM YOUR 75-509
Due to the band of operation (462/467 MHz) the 75-509 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 75-509
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.
PREPARATION
BATTERIES
75-509 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. If the 75-509 is supplied with Ni-Cad batteries and a
wall charger. Ni-Cad 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.
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 18-396
charger into any 110/115 V wall socket.
Plug the cord into the jack on the
bottom of the radio under the rubber plug
marked “CHG”. Charge the
batteries for at least 10 hours.
DO NOT attempt to charge any type of Alkaline batteries in this radio.
BELT CLIP
The 75-509 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.
QUICK USE INSTRUCTIONS:
1.
2.
3.
4.
5.
6.
7.
Install fresh alkaline or fully charged Ni-Cad or Ni-MH batteries.
Turn the unit on by turning the volume control clockwise.
Choose PTT or VOX transmit control with the button on the front of the radio.
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 use “VOX” press and hold the “VOX” button for 1 second and talk into the
front of the radio or the headset microphone. (head set is recommended)
To listen release the PTT button. If in VOX stop talking.
Volume and other functions may be adjusted as described later
TO OPERATE THE HANDS FREE VOX
(VOICE OPERATED TRANSMIT)
To get the most use from the “VOX” feature you must first detrmine 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 second of delay,
level three will give you about three 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 5
for instructions.
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 second. 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%.
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.

TROUBLESHOOTING
PROBLEM
No Power
Cannot Receive Messages
Range is Short
Interference/Static
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. 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. Change your location. The interference may be
caused by nearby electronic or electrical equipment.
CARE OF RECHARGEABLE NI-CAD AND NI-MH BATTERIES
ALWAYS DISPOSE OF BATTERIES PROPERLY
Always follow the battery manufacturers 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.
