3- Tone/Pulse Switch; 4- Time Break Recall Setting; 5- Wall Mounting - Geemarc CL100 Handbuch

Setting up
3 – Dialling mode (Tone/Pulse) settings
The Tone/Pulse switch is factory pre-set to Tone position. In
the UK, all telephone exchanges now use Tone (T) dialing. If
your phone does not dial out, it is probably being used from
an older private switch board (PBX). In this case, the
Tone/Pulse switch must be changed to Pulse (P).
4 – Time Break Recall setting (300/100)
Your phone works with a time break recall for United
Kingdom (R=100ms). It can be switched to 300ms for other
locations or PBX's.
5 – Wall mounting
To wall-mount your telephone, turn the "clip" (located in the
base unit, just below the ear piece).
This will ensure that the handset stays firmly in position.
