Docking station usage

To charge the Remote Control Unit Li battery, insert the unit into the docking station 
(unit keyboard towards docking station front). Fully charged, the Remote Control Unit 
will work for around 2-3 months, depending on usage. The 3x AA-dry cells in the 
docking station will be able to charge the Li battery for about 3 years.

Docking station LED indicator

The LED on the front indicates the condition of the Remote 
Control Unit Li battery 

when the unit is inserted into the 

docking station:
WHITE blinking

 = The Li Battery in Remote Control Unit is 

charging.

RED blinking

 = The Remote Control Unit is defective. Please 

contact your Nagra dealer.

Permanently OFF

 = The Li Battery in the Remote Control Unit is 

fully charged or the Remote Control Unit is not properly inserted 
into the docking station. Remove and reinsert the unit into the 
docking station. If the LED blinks white everything is OK, if not, 
the 3x AA-dry cells are exhausted and must be exchanged.

Battery installation/exchange in docking station

Open the battery box by removing the bottom panel of the 
docking station (magnet lock). Insert your thumb nail into the 
groove and lift the panel up. Replace empty batteries with 3x 
new AA-dry cell batteries. 

Note

When the Li Battery in the Remote Control Unit is fully charged, the 
docking station only uses a small amount of current to maintain 
the full charge. There is no risk of overload even if the Remote 
Control Unit is inserted in the docking station for a long time!

WARNING

Do not use any mechanical tool to open the docking 
station battery box; you could damage the body or 
the panel of the unit!

By ensuring battery is disposed of correctly, you will help prevent 

potential negative consequences for the environment and human 

health. The recycling of materials will help to conserve natural 

resources. For more detailed information about recycling of battery, 

please contact your local authority, your household waste disposal 

service or the shop where you purchased the battery.
