* '''Foyer and stairwell light switches''' can be found on the right-hand wall, just around the corner to the right, at the foot of the stairs (foyer light switch on the right, stair lights on the left). There is a second switch for the stairwell lights at the top of the stairs.
* '''Light switches on the left at the top of the stairs.''' The left-hand switch is for the stairwell lights; the other for the observing floor incandescents.
* The '''switch for observing floor fluorescent lights''' is located up the ladder on the observing floor, on the dome control box console mounted on wall above the North end of the pier.
* The '''slew lights''' on the ring beam are software controlled.
=== Ground floor facilities ===
As you enter the dome on the ground floor, you will find the following facilities:
* '''Fire extinguisher:''' mounted on the wall as you enter.
* '''First aid kit:''' on a shelf to the right as you enter the dome.
* '''Toilet:''' through the first door on the left as you enter the dome. The light switch is outside the door on the right. The right-hand switch operates an extractor fan(!).
* '''Kitchen:''', second door on the left. It has a microwave, coffee maker, kettle, toaster, snackwich and an array of cutlery and crockery in the cupboard under the sink. There are jars of teas, coffees, hot chocolate and sugar. If these jars become empty, return them to the hostel kitchen in your night lunch bag for refilling. The kitchenware is cleaned daily by the hostel staff, except at weekends.
=== The warm room ===
The warm room is the door on the right-hand side, opposite the kitchen. It contains an air-conditioned server room and has the following resources at your disposal:
* A PC ("lesedi-nuc") for running the telescope and instrument control systems.
* Several network cables and power sockets for use with laptops.
* Lights on a dimmer switch (push and hold to adjust the brightness) and a desk lamp.
* An air conditioner to heat or cool the room.
* A stereo compatible with iPods and iPhones, and plays CDs, MP3s from DVDs and USB devices, and has a radio.
=== The Observing Floor ===
At the top of the stairs, be careful not to trip over the raised hatch in the floor (this is for lowering the primary mirror for aluminising). You will find Lesedi on a raised pier, surrounded by a metal grid floor, accessed by a ladder. The North end of the pier is nearest the stairs. Familiarise yourself with the following:
* '''Dome control console''' at the North end of the pier.
* '''Dome lockout switch''' beside the dome control console at the North end of the pier. '''Note that this does not lock out the telescope, only the dome.''' Lockout should be switched on (a red light on the box will flash) if people are working on the dome, otherwise left off.
