Advice
•Do not use options or accessories not specified by
Entel
•Ensure that the radio is used within the parameters
for which it was designed
•Please switch the transceiver off before connecting
optional accessories
Warning
Turn the transceiver off in the following locations outside
of the radio’s ATEX approval rating:
•In explosive atmospheres (flammable gas, dust
including metallic & grain powders etc)
•Whilst taking on fuel or while parked near fuel
station
•Near explosives or blasting sites
•In aircraft, medical institutions or near persons
known to be wearing a pacemaker
Caution
•Do not disassemble or modify the transceiver for
any reason
•Do not transmit while touching the antenna
terminal or any exposed metallic parts of the
aerial as this may result in a burn
•Please check and observe regulations in your
country with regards to use whilst driving
End of Life Disposal
•When your Entel transceiver reaches the end of its
useful life, please ensure that the unit is disposed of
in an environmentally friendly way. For country
specific information please see:
www.entel.co.uk/recycling
Cleaning your Radio
After exposure to any potentially corrosive substance
including salt water it is recommended to thoroughly
wash the transceiver in fresh water. If washing with the
battery removed from the radio, ensure that the battery
is not immersed in
water & clean only
with a damp cloth.
Note: Do not
wash the
transceiver if you
suspect the
waterproofing seal
may be damaged.
Please return to
your supplier for
inspection / repair.
Battery care
Introduction
Your Entel radio is supplied with a high performance
Lithium Ion (Li-Ion) battery. These batteries:
•Extend talk time
•Reduce the battery’s size and weight
•Do not suffer from ‘memory effect’ that reduces the
life of Ni-Cad and NiMH batteries
•Have a low toxicity, therefore reducing the impact
on the environment
Battery Pack Precautions
•Switch the transceiver OFF before charging
•Charge the battery pack before use
•Do not recharge the battery pack if it is already fully
charged.This could lead to a premature battery
replacement warning message (See Battery
Communications on page 4)
•Charge the battery in accordance with the
instructions enclosed with your charger
•Do not charge the transceiver and/or battery pack
if they are wet
The battery pack includes potentially hazardous
components. Please:
•Do not disassemble or reconstruct battery
•Do not short-circuit the battery
•Do not incinerate or apply heat to the battery
•Do not immerse the battery unless attached securly
to the radio in water or get it wet by other means

Common
Battery care / information
•Do not charge the battery near fires or under
direct sunlight
•Use only the specified charger and observe
charging requirements
•Do not pierce the battery with any object or
strike it with an instrument
•Do not use the battery pack if it is damaged in
any way
•Do not reverse-charge or reverse-connect the
battery
•Do not touch a ruptured or leaking battery
If liquids from the battery get into your
eyes, immediately:
•Wash your eyes out with fresh water avoiding
rubbing them. Seek medical treatment
Battery Pack
•If a battery is not to be used for an extended
period of time (e.g. several months) remove the
battery pack from the equipment and store in a
cool and dry location (around 0°C) part charged.
Do not fully discharge the battery before storage.
•Each charge cycle reduces the battery’s life.
Minimise the number of times you charge your
battery especially in hotter environments which
further shortens a battery’s life.
The battery pack has an over-current protection
circuit fitted.When charging a completely discharged
battery i.e. first charge, ensure the battery is removed
from the radio and then re-attached (if fitted to radio
when charging).This will reset the protection circuitry
and ensure normal operation.This process will need
to be repeated if the battery is allowed to completely
discharge in the future. In normal use this is unlikely.
Battery Communications
Each battery used with your radio has a
microprocessor fitted, which logs the number of times
your battery has been charged.
On a radio with an LCD display, the number of times
the battery has been charged, together with the
remaining charge cycles available, will be shown during
switch on (if not de-activated by your dealer).
The warranty on all batteries is 12 months or 450
charge cycles, whichever is the sooner. After 420
cycles, at switch on the radio will emit a series of
short tones, and on LCD models a waste bin icon will
flash to alert you to the need to buy a new battery.
After 450 cycles, at switch on the radio will emit a
series of long beeps, and on LCD models the message
will change to BATTERY COUNT EXCEEDED
REPLACE BATTERY. The radio will continue to
operate but its operational time may be reduced,
eventually failing all together.
Note: only genuine Entel batteries should be used.
Only genuine batteries offer the battery charge count
feature informing you when the battery is reaching the
end of its useful life. Non ATEX batteries will not
work on ATEX radios ensuring customer safety.
Customer satisfaction is assured as you can not be
supplied with sub standard, potentially dangerous
battery packs from 3rd party manufacturers, ensuring
it delivers the expected capacity and endurance.
On HT series batteries a breathable membrane is
used.This is clearly marked on the battery label.
Piercing the membrane will allow water ingress to the
battery and will invalidate the warranty.
