Clock menu operation (v0.1)
First of all try to imagine a virtual 'air button' above the clock with 2 positions, one about 6 inches from the base and the other about 8 inches. The higher one is the 'up' key and when active a 'П' is displayed on the centre tube. The lower one is the 'select' key and when active a 'n' is displayed on the centre tube.
It takes a bit to get used to it but once you have the 'knack' it's quite easy.
To change the display to minutes-seconds or date: Bring your hand down quickly to about 4 inches from the clock and back up again. Repeat to change modes, if left for about 10 seconds the display will revert to Hours-Minutes unless 'sticky display' mode is active.
There is a 3-level menu tree. To activate the menu hold select (n) until the clock beeps: This will select the settings menu. (indicated by the leftmost tubes displaying 9 and . ). To select an option move to 'up' (П) and the second left digit will start to increment, starting at zero. Quickly move down to 'select' when you reach the right option.

Menu tree branch 9: Alarm/time/date entries. These options require all 4 digits to be set before saving. If at any time you make a mistake just leave it for a few seconds and the clock will exit menu mode back to the time display.

(n) to scroll value then (П) to stop, hold until beep to enter and move to the next digit. Repeat for all 4 (HH MM). The display will show HH + MM alarm time for 5 seconds then return to clock mode and set alarm on. The leftmost DP will be lit to indicate the alarm is set.

(>) to scroll value then (n) to stop, hold until beep to enter and move to the next digit. Repeat for all 4 (HH MM). The display will show HH + MM dim on time for 5 seconds then return to clock mode.
Selecting this menu option then allowing it to time out will DISABLE dimming.
9-3 : DIM TIME STOP SET: Hold (П) until third beep: Dim time on/off set. Display shows 93. + 00. Move down to (n) and hold until beep to select. Display shows 0.0 00 or previous dim off value with the flashing DP indicating which digit is currently selected to change.
(>) to scroll value then (n) to stop, hold until beep to enter and move to the next digit. Repeat for all 4 (HH MM). The display will show HH + MM dim off time for 5 seconds then return to clock mode.
Selecting this menu option then allowing it to time out will ENABLE dimming.
9-4 : TIME SET: Hold (П)until fourth beep: Time set. Display shows 94. + 00. Move down to (n) and hold until beep to select. Display shows 0.0 00 or previous time value with the flashing DP indicating which digit is currently selected to change.
(>) to scroll value then (n) to stop, hold until beep to enter and move to the next digit. Repeat for all 4 (HH MM). The display will show HH + MM time for 5 seconds then return to clock mode. Note seconds can't be set directly and are set to zero when the final digit is set. Time the last select for a minute rollover.
9-5 : SET DATE: Hold (П) until fifth beep: Date (days and months) set. Display shows 95. + 00. Move down to (n) and hold until beep to select. Display shows 0.0 00 or previous date value with the flashing DP indicating which digit is currently selected to change.

(>) to scroll value then (n) to stop, hold until beep to enter and move to the next digit. Repeat for all 4 (OO YY). Display will show OO + YY for 5 seconds then return to clock mode.
Note on the timezone offset: This is only required if GPS synchronisation is used and is calculated as follows: 1-12: Adds 1-12 hours to the current GMT value received. 13-23: Subtracts 1-11 hours from the current GMT value received.
9-7 : SET CALIBRATION OFFSET: Hold (П) until seventh beep: Tick calibration set. Display shows 97. + 00. Move down to (n) and hold until beep to select. Display shows 0.0 00 or previous value with the flashing DP indicating which digit is currently selected to change.
(>) to scroll value then (n) to stop, hold until beep to enter and move to the next digit. The first digit is compensation on/off (0/1), the second digit is polarity (0/1) to add or subtract the compensation value. Third and fourth are the compensation value from 0-99 which will be added or subtracted from the 1/250 second counter once per hour, allowing up to +- 0.4 seconds adjustment per hour if required. Display will show the selected data for 5 seconds then return to clock mode.
The minimum time step adjustment is approx. 0.56 parts per million.
