hand controller should display the same.
2. GPS Status: Indicates if there is GPS or GPS is connected to the satellite. HEM44 does not have a
GPS. The GPS status will be always OFF.
3. Right Ascension: Right Ascension of the telescope, or R.A.
4. Declination: Declination of the telescope, or DEC.
5. Azimuth: Azimuth of the telescope (north is 0º, east 90º, south 180º, and west 270º).
6. Altitude: Altitude of the telescope (degrees vertical from the local horizon - zenith is 90º).
7. Mount Status: Display current operation status of the mount.
Stop: mount is not moving;
Slew: mount is moving with an arrow key is pressed;

2.5. Install and Check the Hand Controller Battery
The hand controller uses a button battery to keep the Real Time Clock running. The battery is a
CR2032 Lithium battery, which is not included due to shipping restrictions.
Open the HC back cover with a good, size 1 (4mm) Phillips Screw Driver. With b sign facing
up, slide the battery under two small metal hooks on the positive side first. Then push the battery down to
make a good contact. Make sure that two spring contacts on the negative side are underneath the battery. If
none of the metal pins in battery holder can be seen after battery installed, the battery is not installed
properly.
