seconds with full current. After 30 seconds, and if the transmitter is unused, the charge current is
reduced to maintenance charging and the CH lamp will start flashing.
If the transmitter has been in operation longer than 5 minutes, the CH lamp will light constantly,
indicating that charging is at full current. When the battery energy has been restored, charging is
reduced to maintenance as long as the transmitter is in the charger. If the power of the receiver is
switched off, stored information regarding transmitter operation time, is erased.
The charging of the transmitter battery is controlled by the software in the receiver, and it is

recommended always to leave the transmitter for charging. The charging current is limited to 50mA
during full charge, and the charging time is regulated by the receiver software. The battery
temperature will never rise above +50ºC and will not be a hazard for the EX environment. In case of
a short circuit of the battery connections, an integrated temperature- and current fuse, will brake
the internal connection to the battery cells, and will secure a temperature allowable in EX
environment.
With a fully recharged battery the operational time is more than 12 hours. This means that the
Deadman button on the transmitter might be held operated for more than 12 hours before it stops
transmitting.
Note that operation of the transmitter in low temperatures reduces the capacity of the battery down
to 30% of normal capacity at room temperature. At temperatures lower than -20C, the battery may
"freeze" and lose all its capacity.
NOTE: Charging the battery, should take place at temperatures not lower than 0ºC and not higher

than +50ºC. Charging outside these limits will results in very low charging current, or no charging of
the battery at all. The battery will however not be damaged.
When operating at low temperatures, lower than 0ºC, do not leave the transmitter in a cold driver's
cabin overnight or for a long period of time. Take the transmitter inside to keep the battery warm.
Charging of the transmitter will normally be finished before the car is back to the depot.
It is recommended to use a CH300-110/23VAC mains charger, if the receiver is installed in a place that
has temperature often outside the recommended limits.
Use only Delta chargers for charging the transmitter, other chargers might overload the battery
and the ATEX/IECEx certification is no longer valid.
5. The type of battery used is a 3,6V 300mAh NiMH. The battery is integrated and a part of the end
section of the transmitter housing. The connection to the printed circuit board is by a small
connector. Defective batteries must be disposed at a proper place, where batteries can be
disposed. Please see chapter 10 for further information.
A normal lifetime for a battery is approximately 500 recharging, or more that 3 years in normal
operation.
NOTE: After July 1. 2003, the new ATEX norms are activated. For the DE212 system, the battery
module and the transmitter circuit board must be replaced with parts produced according to this
norms. This means that repair of the TX212 must take place at Delta RC AS or by a Delta RC AS
appointed dealer. Otherwise EX- certificate may no longer be valid.

5.3 Replacing the battery

Note:
The battery module 02465 and all replaceable parts of the transmitter, must be original parts
delivered by Delta RC AS. Otherwise the Ex certifications are lost, and the customer has to take all
responsibilities. The operator is only allowed to change the battery module, nothing else.
From December 2013, the battery module is changed, in accordance with the IECEx certification. The
new battery module for IECEx is 02465.
NOTE: Battery module 02465, cannot be replaced by the old 02166, but 02465 can replace the old
02166. Old 02166 battery modules are no longer valid for replacement and must be discarded.
