The brightness level of the surroundings at which the display light is to switch on is set here.

    Open the main menu with the MENU button.

    Open the “Settings” menu.

    Enter the code for the “Settings” menu.

See Entering the code or PIN.

The code for the menu is “0005”.

    Open the menu item “Light sensor”.

●   The display shows the current brightness of the surroundings.

●   Below this you set the brightness level at which the display light is to switch on.

The less time the display remains lit, the longer the operating time from one battery charge.

─     The smaller the displayed value, the brighter are the surroundings currently. The larger the displayed value, the darker are the surroundings currently.

─     If the measured brightness during running operation is greater than the set threshold, the display light switches on as previously set (5s or 10s, horn button or menu buttons). If the measured brightness during running operation is less than the set threshold, the display light does not switch on.

    Either: Set a high value as the threshold so that the display light is only switched on if the surroundings are very dark.

Or:

Set a low value as the threshold so that the display light switches on independently of the surroundings.

    Confirm using ENTER.
