PC
Charging cable
Use only the accompanying charging cable.
1 Switch off the PC.

the PS/2 port of the charging cable. The data is
then transferred via the charging cable.

5.2 Charging the mouse batteries
➤ Insert the hollow connector of the charging cable
into the socket on the front of the mouse. It does
not matter whether the PC is switched on or off.
The mouse is charged as long as the PC is
switched on. You can continue working while
charging is taking place.
Tips for charging the alkaline batteries
• Charge the alkaline batteries in the mouse as
soon as the LED on the receiver flashes red.
A total discharge can damage the inner
structure and chemical components of the
alkaline batteries.
• A complete charge of the alkaline batteries lasts
12 to 18 hours. The charging circuit prevents
overcharging. As the rechargeable alkaline
batteries do not exhibit the so-called memory
effect, the charging procedure can be
interrupted several times.
• The PC must be switched on to charge the
alkaline batteries.
• The charging cable can remain connected to
the PC even if the mouse is not being charged.
6 Using the power-save function of
the mouse
The power-save function switches the mouse to
power-save mode after 15 minutes of non-use.
• In sleep mode, the surface on which the mouse
is used is scanned only once per second.
Moving the mouse or pressing a button exits
sleep mode. Sleep mode is preset.
• The mouse switches off in deep-sleep mode.
The battery life is notably lengthened by this.
Pressing a mouse button switches it back on.
Deep-sleep mode must be activated manually.
6.1 Activating deep-sleep mode
1 Remove the batteries from the mouse.
2 Keep the left and right mouse buttons pressed
simultaneously and reinsert the batteries.
The setting is confirmed by 10 flashes of the
optical sensor of the mouse.
Automatic deactivation of deep-sleep mode
When you remove the batteries from the mouse,
deep-sleep mode is deactivated and the mouse
returns to sleep mode. For this reason, the deep-
sleep mode must be reactivated each time after
the batteries are removed.
7 Setting channels
The channels of the keyboard and the mouse are
selected at random from 4,095 channels. The
channels of the keyboard and mouse must be
selected together.
Channel setting is necessary in the following
cases:
• battery change
• malfunctions during operation of several
devices in the 27 MHz frequency range
