Laney LR5 - Manual (Page 10)

DC Power Supply: Your LR5 comes supplied with a 12V DC Power Supply, this is easily
fitted between the mains outlet and the amp. When using the amp with the power supply a
few precautions should be followed:
1). Only use the DC Power supply that is supplied by the manufacturer. The use of other
DC Power Supplies may cause damage or other problems.
2). Turn the power switch to OFF and disconnect any other attached devices, before
plugging in and turning ON the DC Power Supply.
3). When the DC Plug is connected to the socket, the battery compartment is isolated
from the unit. Both the DC Power Supply and the battery tray are independent of each
other.
4). Although no harm will come to the batteries if left in place whilst the DC Power supply is being used, it is recommended
that they be removed. Use either one power source or the other.
Batteries: The use of a DC Power Supply is recommended as the units main power source, however, should you prefer to use
batteries, use only Alkaline type (LR6).
Used continuously the batteries will last for approximately 13 hours. (This will vary greatly with the actual conditions of use).
As the batteries run down, the power indicator on the fascia panel will become dim when the battery power is too low.
Replace the batteries or revert to the DC Power Supply.
Fitting Batteries: When installing or replacing batteries, always turn the power switch to the OFF position and disconnect
any other devices you have may have connected. This prevents damage to your speaker and/or other devices. Follow the photo
sequence to fit a set of batteries.
1). Turn the amplifier upside down to access the battery tray that is located under the chassis, place the amp on a piece of felt
or cloth to avoid damage.
2). Push the catch to release, then lift out the lid of the battery tray and insert 6 AA batteries, ensure that the orientation is
correct to the legend on the tray.
3). When closing the lid of the battery tray, insert the tabs opposite the catch first, then push the lid down until a click is heard.
