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).
