Individual Channel Programming (Multi-Display Timers) (continued)

7

If the action alarm time is to be changed, pressing the UP arrow 
button will increase the value and pressing the DOWN arrow 
button will decrease the value. Every time the UP or DOWN 
arrow button is pressed, the value increases or decreases by 
one count. 

NOTE: If either button is pressed and held, the value begins to 
increase or decrease automatically with the change rate 
increasing as long as the button is held.

When the time value is in minutes:seconds (M:S) the LED for the 
selected channel will be off. After 59:59 the LED will come on 
and now the time value displayed is in hours:minutes (H:M).

NOTE: If the time period value is changed to a time value less 
than the action alarm time value, the action alarm time value will 
be set to 00:00.

9

If the name is to be changed, pressing either the UP or DOWN 
arrow button will cycle between “diSc” or “donE”.

When the desired name has been selected, press the button of 
the channel being programmed to save all changes and exit back 
to the initial programming state with all displays showing “Prog”. 

NOTE: To exit the programming sequence without saving any 
changes momentarily press the PRINCE CASTLE LOGO button.

8

When the desired time has been selected, press the button of 
the channel being programmed to proceed to the next part of the 
programming sequence, programming the end-of-cycle name. 

NOTE: To exit the programming sequence without saving any 
changes momentarily press the PRINCE CASTLE LOGO button.

When parameter changes for all channels have been completed, 
press the PRINCE CASTLE LOGO button to exit Programming 
Mode and return the unit to an operationally ready, idle state.

Programming for Single Display Timers

1

Countdown Mode

NOTE: This mode can only be entered when all channels are idle.

Enter the Countdown Mode by holding the UP arrow button for 6 
seconds. This will determine if all the timing cycles count up from 0:00 
or count down to 0:00. Use the UP or DOWN arrow buttons to toggle 
between count up or count down. The display will indicte “C-uP” or 
“C-dn”. When the desired mode is obtained, momentarily press any 
channel button to save and return to Timing Mode.

NOTE: To return to Timing Mode without saving, momentarily press the 
PRINCE CASTLE LOGO button.

2

Volume Level Selection

NOTE: This mode can only be entered when all channels are idle.

Press and hold the DOWN arrow button for 6 seconds to initiate the 
Volume Level Setup Mode. In this mode the timer’s audio volume can be 
set to one of three different levels by using the UP and DOWN arrow 
buttons. A display will sequence through “SL-1, SL-2, SL-3”. When the 
desired level is obtained, momentarily press any channel button to save 
the setting and return to the Timing Mode.

NOTE: To return to Timing Mode without saving, momentarily press the 
PRINCE CASTLE LOGO button.

Simultaneously pressing both the UP arrow button, DOWN arrow button and the PRINCE CASTLE LOGO button during the first 6 seconds after 
applying power to the timer will reset all channels back to their factory default settings.
