. Proceed as follows to re-
place the module:
1 Switch the measuring instrument off and disconnect
it from the mains.
2 Take out the lamp module (3): Press the two grips
gently together and carefully pull out the lamp mod-
ule until the plug-in connection (2) is visible.
3 Pull the plug-in connection (2) apart and, thus, re-
move the lamp module. Do not pull on the wires while
doing this.
4 Plug in the new lamp module to the plug-in connec-
tion of the instrument. Do not touch the lamp with the
fingers.
5 Stow the wires in the opening (1) of the measuring in-
strument again. Make sure that the wires are not
placed in front of the lamp and that they are not in the
way of the lamp module.
