Product Identification

The Prince Castle Model 755 Series Single-display 4-Channel Timer and
10-Channel Timer are easy-to-use timers that count down in minutes
and seconds, or hours and minutes. Each channel has its own display
and can be programmed independently. Slide in replaceable menu strips
identify the product being timed on each channel, and are replaceable
as restaurant menus change. Both auditory and visual signals are used
to alert busy staff people when a timing function is completed.

Operation

Display

• Individual bi-colored LED for each channel. When activated, the

LED for each channel turns green for the length of the entire
timing cycle. When the timing cycle ends, the LED will flash red.
When multiple timers are running, the timer with the least time
remaining will blink its LED.

• One 4-digit, 7-segment numeric display is used.

• Each channel can be programmed for two different timing

cycles. These are indicated by the display in the idle state as
follows:

(Menu 1)

or

(Menu 2)

• When multiple channels are running, the display will show the

time countdown for the channel with the least time remaining.
To temporarily view the remaining time of a channel not being
displayed, press and hold the channel button.

• If the time is in Hours-Minutes (H:M) the colon in the middle of

the 4-digits will flash. If the time is in Minutes-Seconds (M:S)
the colon in the middle of the 4-digits will be on continuously.

• At the conclusion of a timing cycle the display flashes “0”.

Each of the channels of the 4-Channel or 10-Channel timers operate
in an identical manner.

Press a channel button to activate a timing cycle (a short beep
sounds). The timers can be programmed to count up to a selected
value or count down to 0:00.

NOTE: To cancel any operation in progress, press the related
channel button three times in quick succession (less than three
seconds). The channel LED turns off and the LED of the next
channel with the lowest countdown remaining will blink.

When the count reaches the programmed time value an alarm
sounds (if enabled).

Two different timing cycles can be setup for each channel. These
are called “Menu 1” and “Menu 2”. To change from one menu to the
other, all channels must be idle. Simultaneously press both the UP
and DOWN buttons for 6 seconds. The display will change between
the single-line display (Menu 1) and the three-line display (Menu 2).

Channel Defaults

Scan Function
On models featuring a scan function, the scan button will
sequentially display each active channel’s time remaining.
Press and hold the left scan button to sequence right to left
through each channel. Press and hold the right scan button to
sequence left to right through all the channels. The flashing
channel LED indicates which channel is displayed.
