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

Radio care
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

Common
Battery care / information
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
• 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 drylocation (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.
