on a regular basis, if you are not going to use the AR8600 with the BP8600 for extended periods
(several months), it may be worth considering removing the batteries from the radio (to prevent the cells
deteriorating). It is most important that they are charged before placing them into storage and reusing
them within at least three months, ideally NiCads should be fully cycled not less than once every month
after they have been placed into use, always charge NiCads before placing them into storage.
These BP8600 is not charged at the factory before shipping, so you will need to charge it for 48 hours
before use. Dry cells such as Alkaline or Zinc / Manganese cannot be used, the AR8600 charging
circuit is not designed to recharge dry cells or NiMHi batteries.
Fitting batteries
The optional BP8600 battery pack must be fitted in a workshop.
1-6-2 Charging the optional BP8600 battery
The optional BP8600 is intended to be charged while inside the AR8600 while connected to an external
12V d.c. power supply. Switch the AR8600 to STANDBY by pressing the key for more than
one second (or switching off the AR8600 using the PWR/VOL control). It will take 48 hours for the
BP8600 to fully charge, the BP8600 will not successfully charge when the AR8600 is in operation.
The AR8600 will provide around 2 hours of continuous
operation with one third volume and constant reception
with the backlight switched off. The operational time
between charges will be dependant upon volume level
and operating parameters, the power save facility will
also extend operating time.
If connected to an external power supply, the AR8600
many be used for continuous operation regardless of
the charge status of the NiCad battery (the charge
current being at a very low level).
When the NiCads near discharge, three states will be encountered:-
1. A battery symbol will appear in the extreme top right of the LCD a couple of minutes before the
NiCads completely discharge. The operational cut-off point is difficult to determine making advance
warning brief. The legend will have one diagonal bar representing minimal charge left.
2. The LCD battery legend will become an empty outline... operation will cease almost immediately.
3. The NiCads will expire and the set will power off (the VFO frequencies and last stored memory
may be lost). Connect a 12V d.c. power supply to continue operation or recharge the battery.
