PC. Other settings such as Scrambler, Squelch level or reassigning the 2
side keys for different functions can also be programmed. 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 5 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 flat as it could get damaged if left very flat 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.
Unauthorized batteries may cause failure of protection circuitry and result
in bodily injury and property damage.
Safety Information
1)Do not throw the battery into fire!
2)The battery should be recycled and disposed of correctly.
3)Never attempt to disassemble the battery pack.
Notices
1)Only charge the battery, when the ambient temperature is
between 5℃- 40℃.
2)Please turn off the radio when the battery is charging. Using the
radio during charging will affect the normal charging of the
battery pack and will lengthen the charge time.
3)During charging, do not plug in/pull out the power supply or the
battery frequently, it would affect battery charging.
4)Do not charge when the battery or radio is wet. Please dry it with
a soft cloth before charging.
5)Do not use the charger, cable or battery if it is damaged, cracked
or frayed in any way.
6)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
To Prolong Battery Life
1)Battery performance will degrade when the current temperature is
below 0℃. 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 influence its normal use or normal
charge.
Battery Storage
1)Fully charge a battery before storing for a long time, to avoid battery
damage 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.

Charging the Battery
When the battery capacity runs low, the radio’s red LED will
begin to flash and a voice message “Please charge the
battery” will be heard.
Only use the charger docking station and AC adaptor supplied
with the radio. The battery can be charged whilst it is fitted to
the radio or simply on its own as depicted in the sketch below.
Setup:
Please follow these steps:
1.If the battery is to be charged whilst fitted to the radio, please ensure
that the radio is switched off.
2.Connect the adaptor cable to the back of the desktop cradle.
3.Connect the adaptor to the AC power socket.
4.Insert the radio or the battery into the charger cradle. The Red and
Green LEDs will flash briefly.
5.The following LED display sequence will now show the status of the
charging process as depicted in the table below:
Continuous Red LED indicates that the battery is being charged. The
charging process will approximately take 5 hours.
When the battery is fully charged, the Red LED will change to a green
LED which will be ON continuously. Remove the AC power supply from
the charger pod or remove the Radio / battery from the cradle.
If the Red LED keeps flashing, the battery voltage is below 6V or the
battery could be damaged. If the battery voltage is below 6V, the
battery will eventually begin to charge after some time and the status of
flashing Red LED will change to being continuously ON. If however, the
battery is damaged, the status of the flashing Red LED will not change.

CHARGE TIME is approximately 5 hours from flat to full.
OPERATING TIME is approximately 17 hours on 1W power setting or 10
Hours on 5W power with a fully charged battery if used typically on a
5:5:90 duty cycle.
Note:
1. Make sure the radio is switched off during charging or the charging time
will be longer.
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 flat. If an almost full battery is recharged,
the charging cycles are not optimized.
3. When the battery charge goes flat, the radio’s LED will flash a red light
and the radio will keep reporting “Please charge the battery”.
BASIC OPERATION
Power On/Off
Turn the Power Knob (also called Volume Knob)
clockwise to switch on the radio; you will hear a “di”
sound and a voice message will indicate the current
channel number. Turn counter-clockwise to switch off
the radio. (see Figure1)
Adjust the Volume
Press the programmed SK1 “Monitor” key or
“Squelch Off” key to listen the background noise,
then turn the knob to increase or decrease the
volume. (see Figure2)
Select a Channel
Turn the Channel Selector Knob to select your
desired channel. If the Voice announcement function
is enable, your radio will automatically report the
channel No. where the knob locates. (see Figure 3).
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 (MIC). Hold the radio about
2.5cm to 5cm from your mouth. (see Figure 4). The
radio should be held so that the antenna is vertical.
Receive
Release the PTT key to receive a call and adjust the
volume if needed..

Communication Range
Range will depend on the type of terrain that you are communicating
across.
The ZA-711 uses the VHF (Very 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
different terrains are:
Indoors or Shopping centre 600m-1500m
Building 5-30 stories,
City centre & dense bush 500m-3km,
Residential & over water 2-6km,
Farmland 3-8km,
Top of mountain or building (line-of-sight) 15-50km.
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
environment 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 (car or 4x4) will be less than outside and an
external car antenna kit is recommended to improve communication.
2) Reflection: The signal cannot go through metal or very large structures
such as a hill or mountain, but it can bounce off (like a mirror), go around
and reflect 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
(moisture in the air or storms) that may vary depending on the location
and the weather.

Reading data:
Click on the “READ” left icon (arrow away from radio) and press “OK” to
begin reading the data from the radio. The RED LED on the radio will
flash as data is being read. Once loaded, the data can be edited to the
appropriate channels and settings and then saved or printed for future
reference. See below for instructions on each function.
Writing data:
After data is entered, click the “WRITE” right icon (arrow towards radio) to
program the radio. Press “OK” to begin writing the data to the radio. The
GREEN LED on the radio will flash as data is being written. Once
finished, switch the radio off 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.
PROGRAMMING (OPTIONAL)
A programming cable is needed to program different channels or
functions on the ZA-711. 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
manufacturer website Prolific (driver for PL2303 USB-Serial cable). Install
the correct software (only available from Zartek directly) and plug-in the
cable to the PC. The computer should locate the cable and configure it
automatically. You can check that the cable is working by locating it in
DEVICE MANGER > PORTS > PROLIFIC USB – SERIAL COMM PORT
Software installation:
An ICASA dealer or frequency license is required to purchase or use this
radio. This transceiver will need to be programmed with allocated
frequencies before using. An optional USB programming cable, GE-254,
is available. Email a copy of your valid license [email protected] to
request a copy of the programming software. Install the software on to a
PC by following the installation steps. Once installation is finished, an icon
called “ZA-711” 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 ZA-711 radio. Ensure that
there is a charged battery connected to the radio and switch the radio on.

AUXILIARY FUNCTIONS
The functions below can be programmed in software. Some of the
functions have been switched off before leaving the factory and may need
to be programmed if required.
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 12 seconds, Battery
Save turns ON. When a signal is received or an operation is performed,
Battery Save turns OFF.
Factory programmed on Save On
Beep Tone
A beep tone is sounded when the radio is switched on or the side buttons
presses to activate / deactivate function. If the beep tone is unselected
there will be no beep when switching on or pressing side keys.
Factory programmed on Beep enabled
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, although 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.
Level 0 will disable the squelch function and the radio will receive all
background noise on that frequency at all times. You can set up the
appropriate squelch level via software according to the current
communication environment and requirements.
Factory programmed on Squelch level 5
Squelch Level Checking
Either side key can be programmed to enable this function. When you
press the side key to check the squelch level, the radio will indicate the
level 1-9. There will be no indication if the squelch is at level 0 as it is
disabled.
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: OFF, 30s, 60s, 90s …… 300s
Factory programmed on TOT 90s
Tones
Some channels may have pre-programmed CTCSS/QT/DQT tones. 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 different from the one set up in your
transceiver, you will not hear the signal. 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 50 QT standard
CTCSS tones and 104 DQT which can be selected per channel.
Note: Although using channels set up with CTCSS/QT/DQT tones
relieves you from listening to unwanted calls; it does not mean your calls

Scan Add/Delete
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.
Password Protecting Read Programming
The programming of the radio can be protected from reading using a 6
digit software password. Once a password is programmed and written to
a radio, the user must enter the password in the software before being
able to read the radio. If the password is forgotten, you must contact your
dealer to reset it. It is still possible to overwrite the programming as
normal as no password is required when writing only when reading.
Monitor Momentary
The squelch circuit on the transceiver mutes the speaker automatically,
when no signals are present. So you will not hear background noise.
Press the Monitor key to deactivate the squelch manually. This is useful
when you want to adjust the volume level, or when you need to hear a
weak signal. Monitor Momentary will remove squelch so all background
noise will be heard and all tones (QT/DQT) accepted on the same
frequency.
The LED indicator lights green while the radio is in Monitor mode.
SK1 is Factory programmed on Monitor Momentary
VOX (Voice-operated Transmission)
The ZA-711 has innovative state-of-the-art technology not seen in other
two-way radios with its 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.
will be totally private.
Scan
Either side key can be programmed to activate / deactivate this function.
The 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
seconds, scanning will resume. The radio will announce which channel of
the possible 16 programmed channels has been received. This is very
useful when monitoring a large number of channels and responding to
the correct channel.
Priority Scan
Normal scan will sequence through all the channels in
order until a signal is detected. Priority scan allows
one channel to be checked more often which is useful
when there is one main or more busy channel.
For example: If CH2 is set as a priority channel. So
the scan method will be:
Normal scan is CH1, CH2, CH3, CH4……According
to the sequential scan.
Priority scan is CH1, CH2, CH3, CH2, CH4,
CH2…… checks same channel in between others.
Scan Modes
There are two modes of scanning depending on the user’s type of
communication.
Carrier: Scan will stop and lock when a signal is received and continue
scanning after the signal has gone for 5 seconds.
Time: Scan will stop when a signal is received and continue scanning 5
seconds later.

The radio will begin transmitting when a noise or voice is heard. Ensure
that you speak directly into the microphone of the radio at a distance of
less than 5cm. There are many headset options (see optional
accessories below) which can be used in VOX mode allowing for full
hands-free communication.
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 1-9 levels with 9 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.
VOX Delay time
Once the radio senses a voice and begins transmitting it is possible that
the volume of the voice is lowered or there are pauses in the message
which may cause the radio to stop sending. A VOX Delay time (0.5-3S)
will keep the microphone active for the set time before returning to
receiving mode. This delay time can be chosen to suit your style of
speaking and avoid the message breaking up.
Battery Capacity Indication
Either side key can be programmed to enable this function. The
remaining charge on the battery will be voice indicated using a number
1-4. This is useful in determining when to charge the radio.
4 – Half to Full 100-40%
3 – Medium 39-30%
2 – Semi-low 29-20%
1 – Low 19-0%
SK2 is Factory programmed on Battery Level checking (short press)
Low Battery Alert
When the battery capacity is getting low and indicates a level of “1”, the
radio will alert you with a message “please charge the battery” every 5
seconds unless the radio is recharged.
Note: If the Voice Announcement function is disabled, the radio will
sound a double beep “di di ” sound when going flat.
Call Ring
The side key can be set to transmit a loud 3 second call ring tone to alert
other radios.
SK1 is Factory programmed on Call Ring, Hold in to activate.
Emergency Alarm
Either side key can be programmed with a siren alert as an emergency
notification. When pressed, the siren will be sounded on both the sending
and receiving radios. The siren will stop once the side key is pressed
again, the sending radio is switched of or the time-out timer limit is
reached.
Announce Voice Channel
As the channels are changed, a voice announces the specific channel.
This is useful when using the radio at night. Either side key can be
programmed to activate / deactivate this function.
Factory programmed on English
PTT ID
Each radio can be allocated with a 15 digit ID consisting of digits 0-9 or
A,B,C or D. The PTT ID recognition signal can be set per channel or the
side key can be programmed to activate / deactivate it. The radio can be
programmed to send the ID either at the beginning and/or end of a
transmission. The PTT ID or automatic number identification (ANI) is
used to connect with a repeater or telephone system, or for a control
centre’s communication management to identify this caller’s ID using

Begin of Tx: The radio will send out the ID first before allowing voice
communication once the PTT key is pressed.
End of Tx: The radio will send out the ID at the end of a communication
once the PTT key is released.
Both: The radio will send out the ID first before and after the PTT key is
pressed.
Scramble
Scrambler can be set per channel or the side key can be programmed to
activate / deactivate it. Scrambling technology use a coded algorithm to
invert the audio signal and make it unintelligible unless the other radio
also has the same descramble function. This function is used to achieve
extra privacy on the same channel.
Compander
A compander can be set per channel or the side key can be programmed
to activate / deactivate it. The compander will make communication more
clear by improving the ‘Signal to Noise Ratio’ using compression and
amplification technology and decrease the noise when receiving a signal.
Power Selection
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 (1W) or High (5W).
SK2 is Factory programmed on Power selection (long press).
Busy Channel lock out
The transceiver can be programmed with channel lock-out. When set,
this function will disable the PTT button from transmitting if there is any
activity on the same frequency with a different QT/DQT tone. This
prevents interference in community repeater systems.
Factory programmed on BCLO off
