1.4 Hanging the Phone on the Wall
Your telephone is also suitable for wall mounting. Use two screws for fixing. Drill two holes vertically, one above the other, 67mm apart, and leave the screws protruding from the wall by 5mm. Now place the telephone without the desk support over the screws and push it slightly downwards.
There is a small hanging device in the receiver rest to prevent the receiver from falling when it is placed on the rest with the telephone mounted on the wall. Using a small screwdriver, turn this hanging device until a small hook appears at the upper end.
If you are using the telephone fitted to the wall, you can hang the receiver on the telephone without hanging up. You will find a small hook for this purpose at the upper end of the receiver rest.

The ringer can be adjusted from a loud (HI) to a soft (LO) sound level. When you don’t want to be disturbed, slide the RINGER switch to the OFF position. You can still make outgoing calls without being disturbed by incoming calls.

You can adjust the receiver volume for a more comfortable listening level. Set the RECEIVER switch to NORM position to have a normal sound level, and set the switch to HIGH position to have a louder sound level.
