BATTERY INFORMATION

Initial Use

New batteries are not charged fully in the factory. Please charge the battery for 4 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.

05

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)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.

PROFESSIONAL TWO-WAY RADIO

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.

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, and 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

13 and adjust the volume if needed.

PROFESSIONAL TWO-WAY RADIO

Communication Range

Range will depend on the type of terrain that you are communicating across.

The ZA-758 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 different terrains are:

Indoors or Shopping centre 300m-1200m

Building 5-30 stories,

City centre & dense bush 500m-2km,

Residential & over water 2-6km,

Farmland 3-7km,

Top 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 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 a 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

14

PROFESSIONAL TWO-WAY RADIO 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.

PROFESSIONAL TWO-WAY RADIO

PROGRAMMING (OPTIONAL)

A programming cable is needed to program different channels or functions on the ZA-758. The programming cable links the radio to USB port on a PC or laptop.

Sub-tones:

The CTC/DCS DEC column shows the sub tone assigned for each frequency.

There are 50 QT (CTCSS quiet tones) and 104 DQT (digital quiet tones that can be selected. This effectively gives the user 2002 ((8+5)x(50+104)) channels to communicate on. These tones are used to privatise conversations and reduce interference from other users on the same frequency. There are 38 CTCSS standard tones (1-38) plus 12 extra

QT tones and 104 digital codes. 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.

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.

22

PROFESSIONAL TWO-WAY RADIO

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 are 38 standard CTCSS tones (see table for allocated tones), 12 QT 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 will be

23

PROFESSIONAL TWO-WAY RADIO

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.

24

PROFESSIONAL TWO-WAY RADIO

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 Programming

The programming of the radio can be protected 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-758 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. The radio will

25

PROFESSIONAL TWO-WAY RADIO

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.

SK2 is Factory programmed on VOX, sensitivity level 7 of 9 with a delay of 1.5 seconds.

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.

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

27

PROFESSIONAL TWO-WAY RADIO repeater or telephone system, or for a control centre’s communication management to identify this caller’s ID using other radios equipped with a DTMF Decode function.

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.

OPTIONAL ACCESSORIES

EXTERNAL ANTENNA KIT

A main feature on the ZA-758 radio is the detachable antenna. An external antenna can be connected to the radio and improve radio clarity and range when using the radio in a vehicle or building. Radio signal strength is reduced by metal and concrete enclosures. When the antenna is placed outside the signal propagation and clarity improves significantly. Communication range is approximately doubled when using the car external antenna. Also note that, the higher the antenna is placed, the further the range.

GE-277 car kit consists of a magnetic mount rain-proof antenna with cable and car charger.

GE-263 house kit for buildings includes an “L” bracket antenna mount with 8m cable
