- counts the number of partial charging cycles and suggests a recovery cycle after 16 partial charging
cycles;
- stops the charging or recovery cycle immediately if the inside temperature of the BP 4000 is too high
or too low, protecting the charger and transmitter from damage.
The charger checks whether the batteries inserted are dry batteries, standard rechargeable batteries, or
a BP 4000 Battery Pack and will automatically deactivate the charging function if it detects dry or stan-
dard rechargeable batteries.
There are two indicator LEDs in front of each charging slot.
The tricolor (red/orange/green) CHARGE LED indicates the current operating status of the charger.
The tricolor (red/orange/green) RECOVER LED alerts you to the necessity of running a recovery cycle for
the BP 4000 and indicates the current recovery status.
The RECOVER key starts the recovery cycle.
The DC 12 V jack on the rear panel accepts the DC cable on the included power supply or a connect-
ing cable to the optional PSU 4000 central power supply.
1. Check that the AC mains voltage stated on the included power supply is identical to the AC
mains voltage available where you will use your system. Using the power supply with a differ-
ent AC voltage may damage the unit.
2. You can power the charger in one of two ways:
• Use the included power supply.
• Connect the DC 12 V jack to the DC OUT 2 or DC OUT 3 12 V output jack on the optional PSU
4000 central power supply. (DC OUT 1 is reserved for powering a complete antenna network.)
3. The charger is ready to operate. Note that all LEDs remain dark.
The CU 4000 charger has been designed specifically for charging the BP 4000 Battery Pack and
will not charge any other type of rechargeable batteries.
All BP 4000 Battery Packs are delivered uncharged. Therefore, you will need to charge each new
BP 4000 before using it. (Refer to section 4.5 Initial Charging Cycle.)
Each charging slot features two LEDs that indicate the current operating status of the respective charg-
ing slot (">...<" marks an LED flashing in the indicated color):

RECOVER
--- The charger is ready to operate,
no transmitter or BP 4000 is
inserted in a charging slot.
--- The inserted transmitter or
BP 4000 is being checked.
The test takes about 4 to 10 secs.
--- The BP 4000 is being initialized.
(This is only needed if the battery
voltage is too low to power the
circuitry on board the BP 4000.)
--- The BP 4000 is being charged.
--- The BP 4000 is fully charged; the
charging cycle is completed.
--- The charging cycle has been
stopped because of an error.
Refer to section 6 Troubleshooting.
>orange< The BP 4000 is being charged,
and a recovery cycle is recom-
mended.
>green< The BP 4000 is being charged
and the RECOVER key is being
pressed.
>orange< The BP 4000 is fully charged, and
a recovery cycle is recommended.
>green< The BP 4000 is fully charged; the
RECOVER key is being pressed.
red Recovery cycle: the BP 4000 is
being charged.
red Recovery cycle: the BP 4000 is
being discharged.
