Battery Care / Information
• 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 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 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.
