isolate any heat emission from the electronic board) this will affect them and offset
their temperature readout by 2-3 °C. When charging cycle ends, the battery is
cooled down and temperature sensors readout return to normal values.
To reinitiate a battery charge sequence, USB cable should be re-inserted and
battery should be lower than 90% of its capacity.
This ensures that during remote operation of the device the battery will not produce
heat so it won't enter, periodically, into battery charging cycles. Therefore, the
sensors are not get affected by any abnormal temperature fluctuation.
If you intend to mount permanently the device on your observatory, you can open
the back of the device (remove the two screws and lift the back plate) and easily
remove the whole battery or just disconnect one battery clip.
USB OPERATION
2.4
The device has a USB-C socket on its right side that charges the internal battery
pack, and most important, exchange information with your PC. The USB
communication is USB 2.0. Maximum cable length that ensures a stable
communication between Uranus and your PC is up to 5 meters / 15 feet.
Device prefers the USB power channel (+5V) so when the USB cable is inserted,
the device instantly switches to USB power and battery power consumption falls
to zero. When you remove the USB, device instantly switches back to battery
power consumption, operation (no disruption in device operation happens).

POWER CONSUMPTION AND SLEEP MODE
Uranus consumes 60mA during its normal battery operation. When the device is
on battery "mobile" mode (USB cable is not plugged) device enters into sleep mode
after 5 minutes of inactivity (default sleep interval – can be changed from Unity
software). Sleep mode is practically, to the user experience, a full shut down of the
device.
