Using the components

Charging the rechargeable batteries

CAUTION!

• Only use the charging case for charg-

ing the SK 2020 D bodypack transmit-

ter, the HDE 2020 D and EK 2020 D

receivers and the BA 2015 accupack.

• Never try to charge other rechargeable

batteries or non-rechargeable batter-

ies!

Charging the accupack in the bodypack transmitter

To charge the bodypack transmitter in the EZL 2020-

20 L charging case:

 Place the transmitter with the accupack inserted

into the charging compartment for accupack/body-

pack transmitter  as shown in the diagram on the

left

.

When placed into a charging compartment, the

bodypack transmitter automatically switches off.

The red LED CHARGE/ERROR  of the charging

compartment lights up.

After the accupack has been fully charged, the green

LED READY  lights up.

쐋



Notes:

• Charging a completely discharged accupack takes

approx. 3½ hours at room temperature.

• Alternatively, you can remove the accupack from

the bodypack transmitter and insert it into the

charging compartment for accupack/bodypack

transmitter  as described in the following

section.

• The charging case has no error indication like the

one on the L 2015 charger (“red flashing LED”).

Tourguide2020_516509_0909_Sp6.book Seite 33 Montag, 22. März 2010 1:12 13

Using the components

Charging the BA 2015 accupack

To charge the accupack of the radio microphone or



bodypack transmitter:

 Remove the accupack as described on page 26 or

page 27.

 Place the accupack into the charging compartment

for accupack/bodypack transmitter  as shown in

the diagram on the left.

The red LED CHARGE/ERROR  of the charging

compartment lights up.



After the accupack has been fully charged, the green

쐋

LED READY  lights up.

Notes:

• Charging a completely discharged accupack takes

approx. 3½ hours at room temperature. It is

normal for the accupacks to get hot during

charging.

• However, the charging process may take longer

if:

• the accupack is deep-discharged and first

has to be reconditioned by a deep discharge

recovery charge,

• the ambient temperature is close to or over

40°C, since, in order to protect the accupack,

the charging process will be interrupted until

the temperature has dropped to a safe level.

• For safety reasons, each charging process will be

interrupted after 4 hours.

• When not using the BA 2015 accupack for

extended periods of time, charge it about every

three to six months.

Interrupt the charging process and contact

your Sennheiser Service.

Notes:

• Charging a completely discharged rechargeable

battery of the HDE 2020 D takes approx. 2½ hours

at room temperature.

• Charging a completely discharged rechargeable

battery of the EK 2020 D takes approx. 5 hours at

room temperature.

•

However, the charging process may take longer if

:

• the rechargeable battery is deep discharged

and first has to be reconditioned by a deep

discharge recovery charge,

•

the temperature of the built-in rechargeable

battery is over 40°C or below 3°C, since, in order

to protect the rechargeable battery, the charg-

ing process will be interrupted until the tem-

perature is again within the permissible range

(the LED  of the HDE 2020 D or the LED  of

the EK 2020 D flashes red).

34

Tourguide2020_516509_0909_Sp6.book Seite 35 Montag, 22. März 2010 1:12 13

Using the components

• An additional temperature protection prevents

overheating inside the charging case. If the tem-

perature inside the charging case exceeds safety

limits, the charging process will be interrupted

and will only be restarted when the charging case

has cooled down.

• When not using the receivers for extended

periods of time, charge them about every six

months in order to prevent deep discharge

damage to the rechargeable batteries.

Setting a channel

To set the complete system to a certain channel,

proceed as follows:

1. Set the bodypack transmitter/radio microphone to

the desired channel (see next section).

2. Set one of the receivers to the same channel (see

3. Automatically set all other receivers to the same

channel using the channel copy function (see

“Setting the receiver channel(s) using the chan-

nel copy function” on page 37).

Setting the channel on the bodypack transmitter/

radio microphone

To set the bodypack transmitter or the radio micro-

phone to the desired channel, use the operating menu

of the device. An overview of the operating menus is

given from page 49 onwards.
