12V Input
Don’t connect the 110V charger
(No. 4129) to a 220V mains.
Don’t connect the charger parallel to
110/220V mains and a 12V car battery.
Automatic Function Check
• After being plugged in a short automatic function check is run for the
cooling fan and all LED’s except the RX- and TX-LED.
• The CHARGE-LED is red. The charger is ready to use.
• The display shows the DC-Input Voltage (V-INPUT) being usually
11-15V (also when in use with the mains supply).

Displays
Press the DISPLAY SELECT-Button to select different display functions.
The LED indicates the chosen function.
• V-PEAK (Volt):
Displays and stores the highest battery voltage during quick charge
and the lowest voltage during discharge.
• V-INPUT (Volt):
Displays the charger’s DC-Input Voltage. This is important when
charging with a 12V-DC car battery.
• %-CHARGE:
Displays the battery capacity in per cent.
Quick Charge: 0% to 100-120% charged capacity
Discharge: 100% to 0% remaining capacity
• V-BATTERY (Volt):
Displays the actual voltage of the battery being charged.
Battery Connection
•
Connect a Ni-Cad battery
to the proper output. All 3 outputs
can be used at the same time.
• Watch for right polarity: C

Slow Charge (Trickle)
• The slow charge mode is not limited in time and not stopped
automatically. Please refer to the battery manufacturer’s information
regarding charging time.
• The slow charge mode is recommended for Ni-Cad batteries that are
not suitable for quick charge or to refresh old Ni-Cads.
3 different outputs are available for different Ni-Cad types.
1. RX-Output
2-6 Ni-Cad cells with 2.4-7.2V, 70mA charge current
Recommended for RC-receiver packs, Walkman-Ni-Cads (2-3 cells/
2.4-3.6V) and any kind of Ni-Cad battery with 50-700mAh.
– Connect Ni-Cad battery – the slow charge starts automatically.
– The small Control-LED is on to indicate the charge.
– No function when reverse connected, the Control-LED is off.
2. POWER-Output (Ni-Cad-Power-Battery)
4-8 Ni-Cad cells with 4.8-9.6V, 150mA charge current
Recommended for RC-receiver packs, RC-power packs, electric tools
and any kind of Ni-Cad battery with 500-4600mAh.
– Connect Ni-Cad, select CHARGE with the MODE SELECT-Button.
– Slow charge starts automatically with a peep tone.
– The Ni-Cad battery voltage is displayed (V-BATTERY).
– The CHARGE-LED is red.
– When reverse connected, the Ni-Cad is discharged.
3. TX—Output
7-8 Ni-Cad cells with 8.4-9.6V, 70mA charge current
Recommended for RC-transmitter packs and any kind of Ni-Cad
battery with 500-1100mAh.
– Connect Ni-Cad battery – the slow charge starts automatically.
– The small Control-LED is on to indicate the charge.
– The TX-Output is mainly for the use with the mains supply.
– When used with a 12V car battery be sure that it is fully charged
to have a as high as possible input voltage. Otherwise the charge
current might drop too low.
– No function when reverse connected, the Control-LED is off.
