 In previous three cases, arrange properly according to the presence /
absence of the home sensor.
If there is no home sensor (CRUX 170, etc.):
Refresh the PEC Training. The PEC function uses newly trained PEC
data.
If there is home sensor (Early CRUX 200, etc.):
Turn the power off and reboot. Move RA axis from east to west, then west to
east across the home sensor. Each time moving from east to west or west to
east, the melody will sound twice: once when the mount passes the home
sensor (touch message will appear with melody), and once when it moves
away from the sensor (touch out message with melody). Repeat this
movement more than twice. Make sure you hear both touch in and touch out
melody each time you move RA axis across the home sensor.
When the home sensor is recognized properly, the melody will sound and
"H/S" will be displayed at the top of the screen.
If PEC data is valid, the PEC function will be automatically activated.
If PEC function is not activated automatically, redo PEC Training and use
newly trained data to operate PEC function.
n. When using a low rated power supply

DC power supply is recommended to be rated 12V 4A or higher.
When using a low rated power supply, the current must be limited through the
[DC/A Limit] function in the [System] menu to prevent damage to the power
supply.
It is also recommended to lower the acceleration / deceleration values
through the [Acc. Rate] function in the [RA] and [DEC] menus.
o. When the telescope is moving, the TCS reboots or suddenly stops and the
melody sounds.
 This is caused by a voltage drop, when using a low rated power supply.
Change the setting to the lowest possible acceleration setting and the lowest
possible maximum speed.
Replace with a fully rated power supply.

It may be caused by poor contact of the power input DC Jack.
Make sure the power input is loose.
The specifications of DC Jack
Pin Diameter: 2mm, Barrel Outer Diameter: 6.3mm
