Q.
Does the radio need a
licence
to operate? |
|
A.
No
licence is required as the radio operates in a public
frequency band. The ZA-705 is unique as it is set on both
the 464MHz band (5 frequencies) and the 446MHz band (8
frequencies). All Zartek two-way radios are fully
approved by ICASA. This radio has the ability to also operate
on licensed band (403-470 MHz) and on 4W of power if a licence
and frequency is obtained from ICASA.

Q.
What is the
range
of the radio? |
|
A.
The
Zartek ZA-705 can work in any environment or place. Range is
terrain dependant and the figures below are not exact but
just an indication of the performance. Generally the range of
the ZA705 will be similar 10% better than that of the ZA-200
and 20% better than the Pro.
Typical
distances in different terrains are:
-
600m-1000m indoors (buildings, warehouses, shopping
malls, city centre and dense bush)
-
2-6km
outdoors flat (residential areas, over water, farmland
and open/light bush)
-
10-30km
elevated line-of-sight (top of buildings, hills or
mountains range increases with height)

Q.
Can an external antenna
be used on the ZA-705? |
|
A.
A main feature on the
ZA-705 radio is the detachable antenna. This
external magnetic mount rain-proof antenna can be
connected to the radio and improve radio clarity and range
when using the radio in a vehicle or building. The magnetic
mount car kit (GE-270) includes magnetic mount antenna,
drop-in charger and vehicle adaptor.
Radio signal strength is reduced by metal and concrete
enclosures therefore communicate range is low (typically
500m-1km) when using a standard radio with an integrated
antenna inside a vehicle. When the antenna is placed outside
using the magnetic mount, 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. Range increases will be greatest when there is
clear line-of-sight between vehicles and there are no other
vehicles, buildings, trees or mountains obstructing the view.

Q.
Is
the Zartek ZA-705
compatible
with the Pro5, Pro8, ZA-200 and other radios? |
|
A.
The ZA-708 uses both the 446 MHz license-free band (PMR)
which consists of 8 frequencies and the 464 MHz band (5
frequencies). Therefore the radio will be
compatible to any license free radio such as the
Zartek Pro8, Pro5, Eco, ZA708, ZA200.
The radio has been pre-programmed with 16 channels (see
table). Select a channel (1-16) on the ZA-705 and make sure
the other radio's channel corresponds by choosing frequency
(1-8 or 1a-5a) and tone (1-38).

| Q.
Can you program
more channels on the ZA-705? |
|
A.
The ZA-708 uses 5 and 8 frequencies with 50 tones and 106
digital tones. These tones help privatise the communication
and are effectively like separate channels. There are 2028 channel
combinations to select. These can be programmed using the optional
PC programming kit (GE-271) which consists of a PC serial
cable and CD software (software can also be downloaded from
ZA-705 webpage).
The cable plugs into the radio and the user can select
various parameters such as frequency (1-8, 1a-5a), tones (1-38,
12 QT, 106 DQT), emergency call, squelch level, low battery
warning alert and scan. (See users manual for full
explanation)
|
Q.
What battery does
the radio use, how long does it last and how is it
recharged? |
|
A.
A
Li-ion battery is used in the Zartek ZA-705 radio. The
capacity is 1200mAH. Fully charged the battery will
will last for 16
hours (about 2 days of 15
hour usage periods) when used on a 5:5:90 duty cycle
(5% transmit, 5% receive and 90% on-standby). The LED
light will flash when the battery is running flat.
A full charge takes
about 4 hours. Each battery can be recharged 500-750
cycles but exposure to high temperature could decrease the
number of available cycle or even damage the battery. The
battery should be stored with charge as this increases its
shelf life. Li-ion maintains the charge for weeks
unlike other rechargeable batteries. Li-ion batteries have no memory effect and can
be recharged any time.
The battery clips on
to the back of the radio and placed into the
desktop drop-in charger. There is an indicator on
the charger showing charging and full. A vehicle
adaptor (GE-257) is available. Spare batteries
(GE-268) are available and can be charged
separately in the drop-in charger.

Q.
What is the warranty on the radios? |
|
A.
Each radio carries a 12 month factory warranty. This covers all faults that occurred during normal usage of the radio where no customer negligence is present. There is also a full
service department to repair any damaged radios. In case of a faulty unit please contact the store where the radio was purchased so they can send it to us or contact Zartek
directly.
