L 151-10
Charging unit for recharging up to 10 stethoset receivers. The L 151-10 is suitable for
the following stethoset receivers (containing a BA 151 accupack):
• RI 150 • RI 250
• RI 300 • RI 500
• HDI 302
Instead of charging a receiver, it is also possible to charge an individual BA 151
accupack in a charging compartment (e.g. HDI 380).
Power supply
The front of the L 151-10 charging unit features a socket for connection of the NT 92
or NT 2013 mains unit. Use the NT 92 mains unit for powering a single charging unit
or the NT 2013 mains unit for powering two to five cascaded charging units. Do not
use the NT 2013 for powering a single charging unit!
Putting the charging unit into operation
Connect the mains unit to the socket on the charging unit, then plug the mains
connector into the mains. After approx. two seconds, the red LED („CHARGE“) lights
up and the charging unit is ready for operation.
As soon as the charging unit is connected to the mains, the device automatically
switches to normal charging (8 hours). The charging process is indicated by the control
LEDs at the occupied charging compartments. After a charging time of 10 hours, the
charging unit automatically switches to trickle charging. The green LED („TRICKLE CHAR-
GE“) lights up and the red control LEDs at the charging compartments dim (bright = nor-
mal charge, dim = trickle charge).
