2. Press “Mode” to change the selection in the following sequence:
Once you reach the Timekeeping display, you have to hold down “Mode” again to display flashing
hours.

number. Holding down “Up” or “Down” changes the current selection at high speed.
4. After you set the time, press “Mode” to select the Timekeeping Mode.
If you do not operate any button for a few minutes while selection is flashing, the flashing stops
and the clock goes back to the Timekeeping Mode automatically.

Night mode allows you to set the daily tubes and LED backlight shutdown time (hour) and the
daily tubes and RGB backlight activation time (hour). The night mode activation and deactivation
times are set exclusively in the 24-hour format. When the clock is in night mode, pressing any button
will exit the night mode. When configuring the night mode, the digits 01 are displayed on tubes 5
and 6 –OFF:ON:01

Any additional accessories must be connected only when the clock is turned off.
GPS Receiver (GA-6): It doesn't require any setup except specifying the time zone (Menu #6). It
is supported only by Arduino Mega-based clocks. During the initial startup, the GPS receiver may take
up to an hour to determine the precise time. Subsequently, time synchronization occurs every 30
minutes. For reliable GPS reception, the receiver should be placed in a location with a clear view of
the sky. Also, make sure that the connector is fully inserted.
Remote Controller (RM-X153): It doesn't require any setup. For clocks in an opaque case, an
external IR receiver is required. Direct line of sight with the IR receiver (built-in or external) is required
for proper operation. The remote control uses only three buttons: UP, DOWN, MODE, and their
functions are identical to the buttons on the clock. The remote control periodically requires replacing
the CR2025 battery.
Temperature Sensor (DS18B20): It doesn't require any setup. Like any other accessory, it must
be connected before turning on the clock.
