3 Getting Started
Turning the Instrument On and Off 3.1
Turning on the instrument 31.1
1. To turn on the instrument, press [PWR]. The
start-up screen appears. It shows the current
temperature, pressure, date, and time.
2. To change the temperature or pressure value,
use [^] or [v] to move the cursor to the field that
you want to change. Then press [ENT].
3. If you want to initialize the horizontal angle,
rotate the alidade.
4. Tilt the telescope until it passes the horizontal
position on Face-1.
If you have entered your name or your company’s
name in the Owner’s detail field, the text from this
field appears on the start-up screen. To set the
Owner’s detail field, go to MENU > Settings
> Other. For more information, see page 140.
Once you start to use an initialized HA, you must rotate the alidade to initialize the
HA every time you turn on the instrument. If you do this, you can maintain a fixed HA
orientation even if the instrument has moved while it is turned off.
If you tilt the telescope before you rotate the alidade, the horizontal angle is not
initialized, and the instrument uses the previous HA reading.
