 Receiver power  supply
A selection of 4 and 5 cell NiMH battery packs having 
different capacities are available to power the receiver. If 
digital servos are in use, we recommend a 5 cell battery 
pack (6 V) to afford adequate battery capacity. If analog 
and digital servos are used in mixed operation, be sure 
to pay attention to the given maximum permissible 
operating voltage. A stabilized, adjustable power 
supply for the receiver with 1 or 2 receiver batteries 
can be provided, e. g. the PRX-unit, order no. 4136, see 
appendix.
For reasons of safety, do not use battery boxes or dry 
cell batteries.
The voltage of the on-board power supply will be 
displayed at the bottom right of the transmitter's screen 
while the model is in operation.

If the adjustable warning threshold (default value 3.8 V) 
set in the Telemetry menu, see page 217, is underrun, 
an optical and acoustic under-voltage warning will be 
issued.
Despite this feature, be sure to check the condition 
of the battery at regular intervals. Do not wait for the 
warning to be issued before recharging the battery.

Charger cable, order no. 3021, can be plugged directly 
onto the receiver's battery for charging. If the battery in 
the model is connected by way of an order no. 3046, 
3934, 3934.1 or 3934.3 power supply cable, then 
charging can be accomplished via the charging jack or 
special charging connector integrated into the switch. 
The switch in the power supply cable must be in its 
"OFF" position for charging.

 

Receiver battery connection polarity

The charging instructions for the charger as well as 

• 

for the battery from its manufacturer to be observed.
Pay attention to the maximum permissible charging 

• 

current specifi ed by the battery's manufacturer. In 
order to prevent damage to the transmitter, charging 
current should never exceed 1 A. If necessary, limit 
the current at the charger.
If the transmitter battery is nevertheless to be 

• 

charged at a current rate in excess of 1 A, then 
it is imperative that this is done outside the 
transmitter. Otherwise there is a risk of damage to 
the transmitter's board due to overloading its printed 
circuit paths and/or overheating of the battery.
If an automatic charger is to be used for charging, 

• 

perform several test charging procedures to ensure 
the fl awless functionality of its automatic shut-off. 
This applies particularly if you want to charge the 
standard installed NiMH battery with an automatic 
charger unit intended for NiCd batteries Monitor the 
charger's shut-off behavior if it has that option.

Do not execute a battery discharge or battery 

• 

maintenance program through the charger jack. The 
charger jack is not suitable for this purpose.
Alway connect the charger cable to the charger fi rst 

• 

and then to the receiver or transmitter battery. This 
avoids the possibility of shorting the bare banana 
plug ends together.
If the battery heats up signifi cantly, check the 

• 

battery's condition, replace the battery or reduce the 
charging current.
Never leave a charging battery unattended.
