lengthen the charge time.
6) During charging, do not plug in/pull out the power supply or the battery
frequently, it would affect 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 influence 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 different 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 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. 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 fire!
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 affect the normal charging of the battery pack and will
