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.
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. On the advanced 8-key and 20-key
models, battery charge cycle information may also be
accessed via the menu. (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 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. 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.

Using Your Radio
Button Key Beeps
The radio will emit a short confirmation beep when pressing any of the function buttons.This
confidence tone confirms the button has been correctly pressed (key beeps may be disabled by
your dealer).
Channel Monitor Button (Dealer Programmable Function)
Tone/squelch defeat disables both CTCSS and DCS tones used and opens the squelch on the radio.
This will allow you to monitor any transmissions taking place that are not on the same
CTCSS/DCS tone on the channel you have selected and listen to any weak signals that may be
breaking up. When activated, you will hear either a rushing noise or any other channel users.
TurningYour Radio On
Turn your radio on using the on / off power button on the front of the radio. The radio will
“beep” and the LED will briefly illuminate yellow. (The beep may be disabled, if required, by your
Entel approved dealer).
Making a Call
Before transmitting on your radio, first ensure that the channel is not in use (yellow or green busy
LED will be illuminated and audio may be heard from speaker).To transmit press and hold the PTT
button on the side of the radio and speak clearly 25-50mm from the microphone. Release the
button to receive.
Transmit Time Out Timer (T.O.T)
A transmit time out timer is enabled on your radio.This will prevent the radio from transmitting
continuously. The maximum transmit duration is set to 90 seconds. If the transmit button is
pressed for this duration, the radio will generate an alert tone 10 seconds before automatically
ending the transmission, when a continuous tone will be emitted (the T.O.T. duration is dealer -
adjustable).
Panic Alarm Siren
The radio has a local panic alarm button, which, when pressed will emit a loud piercing siren from
the radio’s loudspeaker. To operate the local panic alarm, press the orange function button on top
of the radio for a minimum of 2 seconds.To cancel the alarm, simply turn the radio off.
Button Lock (Dealer Programmable Function)
A button lock feature is available to lock the channel control and other side / top function button
modes (except panic alarm). If available, press the assigned button to turn button lock on / off. If a
long button press is used to enable button lock, when unlocking, an error tone will be heard until
the button lock disables.
Low Battery Warning
Alerts you when the battery needs to be recharged. A ‘beep-beep’ audible alert every 20 seconds
and flashing red LED will indicate the battery is towards the end of its duty cycle and needs to be
charged (see battery care on page 4 for information on battery life warning alerts).
Common

Using Your Radio cont...
Channel Scan (Dealer Programmable Function)
Scanning allows you to efficiently monitor radio activity. When scanning, the tranceiver checks for
a signal on each channel and will only stop if a signal is present.
HT446E - To start / stop scanning, press the dealer assigned function button.
HT446L - Turn the channel control to the scan channel assigned by your dealer.
The yellow LED will rapidly flash to indicate the radio is scanning. When a valid signal is detected,
the radio will stop scanning and monitor the transmission.At the end of the transmission the radio
will remain on the channel for 5 seconds allowing you to reply to the call if desired. If you do not
reply within this time, the radio will automatically resume scanning.
Voice Scrambler (Option)
With the optional voice scrambler you can prevent potential eavesdropping on your radios calls
calls by others.This will make your voice transmission difficult to understand by anyone monitoring
the same channel as you are using. If your dealer has made this a selectable feature, follow the
instructions provided by the dealer.
*Due to local regulation, in some countries the scrambler feature may not be available, please
check with your dealer prior to purchase.
CTCSS / DCS
This is used to reduce interference fromother users on a shared two-way radio communications
channel. Where more than one user group is on the same channel, CTCSS or DCS can be used to
filter out other users.This means you will only hear calls from your group of radios. If the channel
you are using is in use by another user on a different tone, the yellow LED will illuminate on your
radio (indicating the channel is in use). Do not transmit while the channel is busy as both
transmissions will distort.
VOX - AutomaticVoice Activation (Dealer Programmable Function)
In VOX mode the radio will react to your voice and transmit automatically without having to press
the PTT button.This is available using the radio without an audio accessory, or with aVOX
compatible accessory.
There is always a slight delay for the electronic switching, therefore starting a transmission with a
lengthy exaggerate or, throwaway, first word is recommended e.g. "H-e-l-l-o Charlie One do you
receive, over".
To enable / disable theVOX feature, press the bottom side function button below the PTT button
for 1 second.
For a list of VOX compatible audio accessories see page 5 of this guide,
contact your dealer or visit www.entel.co.uk
Nuisance Channel Delete (Dealer Programmable Function)
Allows you to remove an interfering channel that you do not want to be part of the channel scan
list.You can remove it by pressing the dealer assigned button when the interfering signal is being
received. Switching the radio off, then on, will reset the radio to its default setting.
