RECHARGING THE ACCUPACKS

For recharging, insert the BA 151 accupack into one of the two charging compartments . If you have a second accupack (available as an accessory), you can charge it in the second compartment.

When the accupack is going flat (you can hear hissing noise and slight sound distortions), switch the headphone receiver off and recharge the accupack.

￿Recharge a flat accupack immediately. If it remains in the headphone receiver and the receiver is then (or remains) switched on, the accupack will be damaged.

￿If possible, use the entire capacity of the accupack. Short discharging/ recharging cycles will reduce its capacity.

N.B.:

Before using the accupack for the first time,

 

it MUST be charged for 24 hours!

NOTE

￿ Charging in the charging compartments works even when the trans- mitter is switched off (“TSP”) as long as it remains connected to the mains!

RECHARGEABLE ACCUPACKS HAVE A “CHARGING CYCLE”

Depending on how long your receiver has been in use, you must also recharge the BA 151 accupack for a certain time. A simple rule of thumb will help you to decide what time is necessary:

Operating time x 3 = recharging time

Example:

1 hour listening

2 hours listening

3 hours listening

3 hours recharging

6 hours recharging

9 hours recharging

OPERATION WITH A SECOND ACCUPACK

By using a second accupack, you can increase the listening time with your receiver. The second accupack is always inserted in the charging compartment of the transmitter to ensure that it is ready and fully charged when it is needed.

￿If you use your system with only one accupack, you must stop after about 4 hours and recharge the accupack for about 12 hours in the

charging compartment of the transmitter.
