Introduction

The MSR+ is supplied with four AA batteries, and

these need to be installed before you can use it.

Note: Dispose of used batteries thoughtfully.

• Press the tab and remove the battery cover on the

back of the MSR+:

• Make sure you observe the polarity of the batteries

and the polarity marks + and – inside the battery

compartment.

• Insert the four AA batteries accordingly:

• Push the battery cover back into place.

Low battery indicator

The indicator normally lights up when you press a key.

If it flashes twice after releasing a key, this indicates

that the battery is low.

Always replace all four batteries at the same time. Do

not mix old and new batteries.

Replace the batteries as soon as possible after the

low battery indicator appears, and after removing

the old batteries replace the new batteries within

two minutes, or you risk losing any codes you have

programmed.
