PROGRAMMING NOTICE!
This transceiver has been factory programmed and can be used immediate-
ly once purchased. All 16 channels have been activated with channels in the
license free bands as per the table below and on the back of the box. There
are 2 bands, PMR 446MHz band with 8 frequencies (1-8) and the 464MHz
band with 5 frequencies (1a-5a). Select the same channel on any ZA-720
radio to communicate.
Compatibility:
The ZA-720 is factory programmed to be directly compatible with all 16
channels on the TX-8, channels 1 to 12 on the ZA-748, ZA-725 and ZA-758
and the rst 8 channels on the ZA-708 if they are set to factory program-
ming. You will need to reprogram your ZA-720 radio when there are other
channels to be set. Both the frequency (1-8 or 1a-5a) and CTCSS sub tones
(1-38) / DCS tone must be the same on all radios for full intercommunica-
tion. Should there be interference on a specic channel, select a di󰀨erent
channel. Note that Channel 9, 10 & 11 are set on the open frequency with-
out a sub tone and channels 13 to 16 have been set with a tone 20 for more
privacy. A sub tone is used to privatise conversations when using the same
frequency.
WARRANTY
There is a 12 month factory warranty on the unit. Warranty does not cover
speakers, battery or accessories. The product must be used for the intend-
ed purpose and not subject to willful or accidental damage. If the product
has been tampered with in any way, the warranty shall be considered null
and void.
SAFETY INFORMATION
yStudy this manual carefully to understand your transceiver well.
yFor safety reasons, it is important that the user is aware of and under-
stands the potential hazards common to using any transceiver.
yTo clean the radio, wipe with a soft cloth dampened with water. Never
use solvents or cleaners on the radio, they can harm the body and leak
inside, causing permanent damage.
yYour radio is not splash proof or waterproof. If the radio gets wet, turn it
OFF and remove battery immediately. Dry the battery compartment to

lengthen the charge time.
6) During charging, do not plug in/pull out the power supply or the battery
frequently, it would a󰀨ect battery charging.
7) Do not charge when the battery or radio is wet. Please dry it with a soft
cloth before charging.
8) Do not use the charger, cable or battery if it is damaged, cracked or
frayed in any way.
9) The battery life is over when the operating time is obviously shorter than
normal even if it’s fully and correctly charged. Please then replace with a
new battery.
To Prolong Battery Life
1) Battery performance will degrade when the current temperature is below
0°C. A spare battery may be necessary in cold weather. Please keep the
cold batteries, as these batteries will work under room temperature.
2) If the battery contact is dusty, it may inuence its normal use or normal
charge.
Battery Storage
1) Fully charge a battery before storing for a long time, to avoid battery dam-
age caused by over-discharge.
2) Recharge the Li-Ion battery after 6 months as the battery will lose small
amounts of charge even when not in use. This regular maintenance will
avoid the battery capacity reducing which is caused by over-discharging.
3) When storing your battery, keep it in a cool and dry place under room
temperature.
An optional programming cable is available to program different PMR
446MHz and 464MHz channels and sub tones on the ZA-720 Software is
available for free download from www.zartek.co.za. The programming cable
is connected to the radio to the USB port on a PC. Other settings such as
Squelch level, VOX or reassigning the side key for di󰀨erent functions can
also be programmed. Licence free use of this transceiver limits the fre-
quencies to the 446MHz and 464MHz bands and the power is restricted to
500mW. If an ICASA license is granted for use of other frequencies (400-470
MHz) and power (2W), special software is available from a registered two-
way radio dealer. The supplier and manufacturer take no responsibility if a
user operates the transceiver not in accordance with ICASA regulation.
Please refer to the sections in this manual for instructions on programming
and the functions available.
BATTERY INFORMATION
Initial Use
New batteries are not charged fully in the factory. Please charge the battery
for 3 hours at least before first use. This initial charge pre-conditions the
battery for full capacity. Failure to charge fully may shorten the life span of
the battery. Recharge the battery immediately once it goes at as it could
get damaged if left very at for long periods. The maximum battery capacity
and performance is achieved after three full charge-discharge cycles.
Battery Pack
Please only use a battery which is approved by the manufacturer. Unautho-
rized batteries may cause failure of protection circuitry and result in bodily
injury and property damage.
Safety Information
1) Do not throw the battery into re!
2) The battery should be recycled and disposed of correctly.
3) Never attempt to disassemble the battery pack.
4) Only charge the battery, when the ambient temperature is between 5°C~
40°C.
5) Please turn off the radio when the battery is charging. Using the radio
during charging will a󰀨ect the normal charging of the battery pack and will

GETTING STARTED
Install & Remove the Battery
Insert the battery pack so that the two bottom protrusions t into the holes
and then close the battery so the battery clip clicks closed.
To remove the battery, lift up the clip at the top back of the radio to release
the battery.
Install & Remove the Antenna
Connect the rubber antenna to the top antenna socket by inserting the plug
and turning in a clockwise direction. Make sure that the antenna is fully con-
nected until tight.
NOTE: That the radio requires the antenna to function. Do not transmit
without an antenna connected as this could damage the radio.
Install & Remove the headset / programming cable
Open the side headset speaker / MIC / USB port cover and then plug in the
accessory rmly into the side jack.
If you want to remove the accessory, unplug it gently and close the cover.
Charging the Battery
yWhen the battery capacity runs low, the radio will announce “Please
change the battery”.
yThere are 2 ways to recharge the radio:
Using desktop cradle: Plug the cable from mains adaptor into the back
of the desktop cradle and then insert the radio in the cradle. Light on the
cradle will show RED when charging and GREEN when full.
Direct plug in: Plug in the cable for the mains adaptor into the side micro
USB charge socket. Light on the radio will show RED when charging and
NO Light when full.
Only use the supplied charging adaptors to recharge the radio and battery.
NOTE: That the battery can be recharged separately from the radio using
the desktop charger.
CHARGE TIME is approximately 3 hours from at to full.
OPERATING TIME is approximately 25 hours with a fully charged battery if
used typically on a 5:5:90 duty cycle on 0.5W power.
NOTE:
1. Make sure the radio is switched o during charging or the charging time
will be longer and number of possible battery charge cycles reduced.
2. Li-ion batteries do not have memory so they can be recharged at any
time. There are a limited number of charge cycles that the battery can
handle, typically 500-700 times. To get the maximum use of the battery,
only recharge when getting at. If an almost full battery is recharged,
the charging cycles are not optimized.

BASIC OPERATION
Power ON/OFF
Turn the Power Knob clockwise to switch on the radio; you will hear an On
sound and a voice message will indicate the current channel number. Turn
counter-clockwise to switch o󰀨 the radio.
Adjust the Volume
Hold in the side “Monitor” or “Squelch O󰀨” button to listen the background
noise, then turn the On/O󰀨 knob to increase or decrease the volume.
Select a Channel
Turn the Channel Selector Knob clockwise to change the channels from 1 to
16. Your radio will report the channel number.
Refer to the factory channel settings when linking your radio to other radios
as it may be necessary to reprogram or adjust the frequency / sub tone to
match.
Transmit
Keep pressing down the PTT key and speak directly into the microphone
hole (MIC). Hold the radio about 2.5cm to 5cm from your mouth. The radio
should be held so that the antenna is vertical. Speak slowly loud and clear
into the radio for a good signal to be received.
Receive
Release the PTT key to receive a call and adjust the volume if needed.
Monitor
The squelch circuit in the transceiver mutes the speaker automatically,
when no signals are present so you will not hear background noise. Hold in
the side button to Monitor a frequency by deactivating the squelch. This is
useful when you want to adjust the volume level, or when you need to hear
a weak signal.
Communication Range
Range will depend on the type of terrain that you are communicating across.
The ZA-720 uses the UHF (Ultra High Frequency) band and will be subject
to similar obstacle interference as cellular phones. The radio works indoors
as well as outdoors. Typical rough estimate ranges for di󰀨erent terrains are:
yIndoors or Shopping centre 300m-1200m,
yBuilding 5-30 stories,
yCity centre & dense bush 500m-2km,
yResidential & over water 2-6km,
yFarmland 3-7km,
yTop of mountain or building (line-of-sight) 10-30km.
When you press the PTT talk button a signal is transmitted and the signal
floods the area in all sideway directions. The signal travels in 3 different
ways:
1) Penetration: The signal can go through materials such as wood, plastic,
cement and fabric. The denser the material or more built up the environ-
ment the weaker the signal will become. The signal cannot go through
solid metal or very large solid land structures such as a hill or mountain.
Metal acts like a shield and that is why the performance from the inside of
a vehicle will be less than from outside.
2) Reection: The signal cannot go through metal or very large structures
such as a hill or mountain, but it can bounce o󰀨 (like a mirror), go around
and reect in other directions as well. This happens at the speed of light.
3) Line-of-sight: Line-of-sight is when there are no obstructions in the path
between the communicating parties. The higher up you go the further you
can see, so the larger the line-of-sight distances will be. Generally you
can talk to wherever you can see, which is why the coverage in a valley
is much less than the coverage from on top of a hill.
Ensure that there is nothing blocking the antenna. The less metal in close
proximity (0-2m) the better the range. There may be external interference
from electrical equipment (power lines or factories) or natural causes (mois-
ture in the air or storms) that may vary depending on the location and the
weather.

PROGRAMMING (OPTIONAL)
A programming cable is needed to program di󰀨erent channels or functions
on the ZA-720. The programming cable links the radio to USB port on a PC
or laptop.
USB installation
USB cable driver software for your computer operating system is available
for free downloading from www.zartek.co.za or from the cable manufactur-
er website Prolic (driver for PL2303 USB-Serial cable). Install the correct
software and plug-in the cable to the PC. The computer should locate the
cable and congure it automatically. You can check that the cable is working
by locating it in DEVICE MANGER > PORTS > PROLIFIC USB – SERIAL
COMM PORT
Software installation
Programming software for the ZA-720 is available for free download from
www.zartek.co.za. Install the software on to a PC by following the instal-
lation steps. Once installation is nished, an icon called “ZA-720 User PC
Software” will appear on the screen.
Connect the USB cable to the PC and plug-in the twin connector into the
speaker/microphone jack on the side of the radio. Ensure that there is a
charged battery connected to the radio and switch the radio on. Start the

After channel and optional feature data is entered, click the “WRITE” icon to
program the radio. Press “OK” to begin writing the data to the radio. Once
nished, switch the radio o󰀨 and unplug the cable from the radio. Additional
radios can be programmed by plugging in the cable to the radio, switching it
on and following the “WRITE” procedure.
To change settings select Edit > Channel Info or > Optional Features
Licence-free bands
The Frequency column refers to the frequencies that can be selected on
the radio. The 8 frequencies in the 446MHz band are represented by the 8
channel numbers, 1-8, in the table. These channels correspond to the chan-
nels on other 446MHz license free radios. The 5 frequencies in the 464MHz
band are represented by the 5 channel numbers, 1a - 5a, in the second
table. These channels correspond to the channels on other 464MHz license
free radios.

Sub-tones
The Tone column shows the sub tone assigned for each frequency. There
are 50 QT (CTCSS quiet tones) and 210 DQT (digital quiet tones that can
be selected. These tones are used to privatize conversations and reduce in-
terference from other users on the same frequency. A CTCSS/QT/DQT tone
is a sub-audible tone which allows you to ignore (not hear) calls from other
parties who are using the same channel. When you receive a signal that
has a tone di󰀨erent from the one set up in your transceiver, you will not hear
the signal but only the LED will show frequency activity. Likewise, signals
that you transmit will only be heard by parties whose CTCSS/QT/DQT tone
matches the tone set up in your transceiver.
There are 38 CTCSS standard tones (1-38) plus 12 extra QT tones. The
38 tones are common on other 446 & 464MHz radios such as the Zartek
Pro8 or Pro5. If the tone is left “OFF”, the frequency is left “open” to receive
communication from any tone, but your transmitter will not be decoded by a
radio with a tone.

OPTIONAL FEATURES
Battery Save Function
The Battery Save function decreases the amount of power used when a
signal is not being received and no operations are being performed (no keys
are being pressed, and no switches are being turned). While the channel is
not busy and no operation is performed for 10 seconds, Battery Save turns
ON. When a signal is received or an operation is performed, Battery Save
turns OFF.
yFactory programmed on Save ON.
Squelch
The squelch level is used to adjust the threshold at which signals will open
the audio channel. A low level will allow weaker signals to be audible, al-
though with more background noise. However, if weak signals are annoying,
the level can be adjusted higher to open the channel only when stronger
signals are received.
You can set up the squelch level from 0 to 9. The higher the squelch level,
the less noisy is the signal as only stronger signal are accepted. The lower
the squelch level the noisier the signal is, as weak signals are also allowed.
As the communication range or obstructions between radios increase, the
weaker the signal becomes. It is advised to use a lower squelch level to get
further communication range.
yFactory programmed on Squelch level 3.
Time-out Timer
The purpose of the Time-out Timer is to prevent any person jamming up a
channel for a long time whilst transmitting. If the time that you continuously
transmit exceeds the set Time-out time, the transceiver will stop transmitting
and a tone “beep” will sound. To stop the tone, release the PTT switch. You
can press the PTT switch again to resume transmitting.
NOTE: you can set up the time level: 15s, 30s, 60s, 90s …… 600s.
yFactory programmed on TOT 300s.
VOX (Voice-operated Transmission)
The ZA-720 has a multi-level sensitivity built-in VOX function. You can enjoy
talking and listening without pressing PTT key as transmit is automatically
activated by sound. This turns your radio into hands-free “walk & talk” when
used with a headset. Voice activation is used to operate the radio in hands-
free mode or as a noise / baby monitor. The radio will begin transmitting
when a noise or voice is heard. There are many headset options (see op-
tional accessories below) which can be used in VOX mode allowing for full
hands-free communication.
NOTE:That VOX can be activated in software and manually.
Manual VOX ON/OFF: First set the channel from CH 1 – 5, then switch o󰀨
the radio. Now Hold in the PTT & Monitor Buttons together and switch radio
On whilst holding them in and then release. The radio will announce VOX
ON. Repeat the process to toggle VOX OFF.
VOX level
The sensitivity level of the microphone can be adjusted to allow different
volumes of sounds to make the radio begin and remain transmitting. There
are 1 - 5 levels with 1 being the highest and most sensitive to lower volumes
of sound. If the radio is used in a very noisy environment it is recommended
to use a low sensitivity level to avoid the radio transmitting unnecessarily. At
low sensitivity level it will be required to speak loudly into the microphone to
activate the radio. At high sensitivity, a soft voice is all that is required which
enable the radio to be placed at a further distance from the noise source
(typically 30cm max).
Scan
A scan function is useful when you want to find other people on similar
frequencies or to monitor communication within your group. If an active
channel is found the scan will stop and lock on to that channel. You can now
transmit and receive on this frequency. When the signal is gone for 5 sec-
onds, scanning will resume. LED ashes when scanning.
There are 2 ways to setup scanning:
1) Via Programming Software: Program CH 16 to be blank with no data.
Select CH 16 to scan. The radio will begin scanning all the selected chan-

·13 · · 14 ·
nels (1-15) and lock on to any activity.
2) Manual SCAN ON/OFF: First set the channel CH 16, then switch o󰀨 the
radio. Now Hold in the PTT & Monitor Buttons together and switch radio
On whilst holding them in and then release. The radio will announce ON.
Repeat the process to toggle Scan OFF.
Scan Add/Delete
In the Channel Info You can add a channel to the scan group or delete it
from group.
Add choose Yes in the channel row under the Scan Add column to add the
channel.
Del choose No in the channel row under the Scan Add column to remove
the channel.
Low Battery Alert
When the battery capacity is getting low, the radio will alert you with a
message “please charge the battery” every 5 seconds unless the radio is
recharged.
Announce Voice Channel
As the channels are changed, a voice announces the specic channel. This
is useful when using the radio at night.
Power Selection (only in dealer license version)
Maximum communication range is achieved when the transceiver is set
to high power mode, whilst lower power settings will save battery life. The
power can be set on low (500mW) or High (2W).
yFactory programmed on low 500mW
Programmable Side Key
You can program specic functions for the bottom - side key via software.
Local Alarm:A very loud continuous emergency siren is sounded.
Monitor: Hold in the side button to Monitor a frequency by deactivating
the squelch. This is useful when you want to adjust the vol-
ume level, or when you need to hear a weak signal.
