Important!
• Use only the following optionally available AC adaptor model with this product:
AD-A70140.
• Use of a AC adaptor model other than that specified above can result in serious damage to the AC
adaptor or the BN Unit, or other serious problems.
• Always turn off the BN Unit before connecting the AC adaptor.
• The AC adaptor may become warm to the touch after very long term use. This is normal and does
not indicate malfunction.
To connect the AC adaptor
Important!
• Be sure to have batteries loaded in the BN Unit, even when using the AC adaptor unit for power.
The BN Unit is designed to disable operation if an attempt is made to operate it under AC adaptor
power, while batteries are not loaded or battery power is low. This is done in order to protect
against corruption of memory contents caused by a sudden drop in power when the AC adaptor is
unplugged from the BN Unit.
• Always unplug the AC adaptor from the BN Unit before replacing batteries.
1. Connect the AC adaptor into the jack on the left side of the BN Unit.
2. Plug the AC adaptor into a standard household AC outlet.
