Attaching / Removing the Belt Clip
5To attach, slot the clip onto the slot on the
b ack of the battery and slide up until you
hear a “click”
6To remove, pull the tab towards the belt
clip (a). Then slide the belt clip
downwards (b)
Attaching / Removing the Aerial
1
To attach, carefully align the aerial with the
socket. Screw in the aerial clockwise (taking
care not to cross the thread) until it is seated
firmly with the accessory cover’s rubber ring
between the aerial & the the top of the radio.
2
To remove, unscrew the aerial anti-clockwise.
12
Attaching / Removing Audio Accessories
3To attach, remove the accessory cover by unscrewing the
locking screw anti-clockwise (leave cover secured under
antenna as this provides a waterproof seal). Attach accessory
plug by locating over the socket. Carefully tighten the locking
screw clockwise until finger tight (do not tighten with a
screwdriver etc).
4To remove, unscrew accessory plug the locking screw by
hand in an anti-clockwise direction (carefully use a coin or
screwdriver if too tight). Ensure you re-fit the accessory
waterproof cover so as to protect the accessory socket.
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
•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

Battery Care / Information
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.
•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 in water
unless attached securely to the radio or
get it wet by other means
•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
Battery Charging
1. Connect the AC adapter to the charger
pod. The LED status light will illuminate
green indicating ready for charge
2. Turn the transceiver off
3. Insert the battery pack into the charger
pod, either with or without the
transceiver attached. The LED status light
changes from green to RED & trickle
charge begins
4. A fully discharged battery pack will take
approximately 6 hours to charge,
depending on the remaining power
condition. When charge is complete, the
LED status light turns green.
Overcharging:
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 Care / Information
Battery Indicator
For your safety and convenience your
transceiver continually monitors the battery
pack and gives an indication on the LCD:
•3 Segments: 12 hours
•2 Segments: 1 hour
•1 Segment: 20 mins
Note: Only genuine Entel batteries should be
used. 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, & will
invalidate the warranty.
Battery
Attaching / Removing the Battery Pack
