Batteries:

This device requires 4 UM3/AA/LR6 1.5V batteries (not supplied). Install the batteries in the battery compartment as shown ("+" and "-"). Incorrect polarisation can damage the equipment. Never use combinations of new and used batteries.

If the device is disconnected from the mains, the stored data can be retained if the connection is restored within 30 seconds. If not, the stored data will be lost, and the stored information must be input again.

Weak battery display ⑫:

This display lights up if the batteries are discharged. The old batteries must be replaced with new ones as soon as possible.

Adapter:

Inserting an adapter into the adapter connector ^14 provides the device with a 6.0V supply. A suitable universal DC adapter (6.0-7.5V) intended for use on different equipment can be obtained from most electrical suppliers.

Warning: Even when using an external adapter, you should always have four UM3 batteries in the battery compartment as a back-up in case of mains power failure.

Protect the equipment from moisture. Never put it on a wet surface.
