RECHARGEABLE ACCUPLUGS HAVE A „CHARGING CYCLE“

Depending on how long your receiver has been in use, you must also recharge the BA 151 accuplug 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 ACCUPLUG

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

PIf you use your system with only one accuplug, you must stop after about five hours and recharge the accuplug for about 15 hours in the charging compartment of the transmitter.
