Levo Digital Clocks and Timers have a dip switch control panel that sets its display settings. To change the factory default settings, from the back side of the clock remove the small rectangular access panel. Setting changes can be made while the clock/timer is ON and changes will take effect within a few seconds.
Note
When power is first applied to the clock/timer or the reset button is pushed, a decimal point will flash for approximately three minutes while its receiver is turned on to search for a Transmitter signal. If the clock does not receive valid time data from the Transmitter for 3 days, the red colon on the clock will flash.
The LED display is set to 100% by factory default.
To dim the LED by 25%, set the OPTIONS, DIM switch 1 to the OFF position and DIM switch 2 to the ON position, as illustrated below.
To dim the LED by 50%, set the OPTIONS, DIM switch 1 to the ON position and DIM switch 2 to the OFF position, as illustrated below.
To dim the LED by 75%, set the OPTIONS, DIM switch 1 to the ON position and DIM switch 2 to the ON position, as illustrated below.
To set the display of a to alternate between the current time and date, set the HR OFFSET- Time/Date switch (1) to the ON position, as illustrated below.
To display 24-hour time, set the HR Offset - 12/24 HR switch (2) to the ON position, as illustrated below.
To enable the PM dot indicator, set the OPTIONS - PM DP switch (6) to the ON position, as illustrated below.
The Clock/Timer displays the time received from the Transmitter. The hour offset is for application use when the clock/timer is to display the time for another Time Zone.
By moving the appropriate “HR OFFSET” dip switch(s) and the direction (+/-) dip switch, any full-hour time can be displayed. The “HR OFFSET” switch designates how many hours are offset from the current Transmitter Time Zone.
The clock reads the hour offset on start up, when the RESET button is pushed, and each time the clock receives data from the Transmitter for the offset hours to go into effect.
The audible buzzer is only on the count-up and count-down timer function. To enable the buzzer feature, set the OPTIONS - Buzzer switch (3) to the ON position, as illustrated below.
For Programmable Timer models, the timer schedule is configured in the Primex Event Scheduler Pro software to the schedule ID controller 24. The schedule is downloaded from the Event Scheduler Pro to the system Transmitter, allowing the Transmitter to broadcast the schedule.
To enable a programmable timer to receive the broadcast schedule from the Transmitter, set the PT/TC Switch (5) to the ON position, as illustrated below.
