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

• 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

• Do not charge the battery pack in a hazadous area

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 and avoiding rubbing them.

• Seek medical treatment

Battery Care / Information

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 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 and 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.

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-attach (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.

Common

Battery Indicator (HTX44 Only)

For your safety and convenience your transceiver continually monitors the battery pack and gives an indication on the LCD.

• 3 Segments: Fully charged

• 2 Segments: 1 hour

• 1 Segment: 20 mins

Note: Only genuine Entel batteries should be used. With Entel batteries customer satisfaction is assured, as you avoid risks from 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.

Battery Communications (HTX44 Only Excluding ATIS models)

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).

Battery Care / Information

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 warning beeps that indicate the number fo times the battery has been charged exceeds the charge count & the battery needs to be replaced.

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.
