“FLASH AND CANCEL” OPERATION
The 12-86-5000 supports a feature that can be enabled if required to provide indication
when a transmission has been sent. This may be desired in an application, such as a
restaurant table top transmitter, to easily determine who was seeking assistance.
The “Flash and Cancel” feature allows a flash duration to be set when a button is pressed,
and also allows a button to be set as a “cancel” to stop any further flashing (for when service
is no longer required, or call has been serviced). When the feature has been enabled
further transmissions are not possible until the cancel button has been pressed, the
programmed flash period has expired or the LED has been flashing for at least 30 seconds -
this is to prevent transmitter misuse.
To use this feature:
Programming the message for any button as "****" will set the button as a flash cancel
button. Any number of buttons can be set as a “cancel”. When a cancel button is pressed
the red LED will flash twice slowly, stopping any further flashing.
“Flash and Cancel” operation is enabled by prepending the set message with [NNN] (where
N is exactly 3 digits enclosed in square brackets) e.g. to send the message “Service
Required” and then flash the LED for 90 seconds the button message should be
programmed with “[090]Service Required”. The “[090]” part of the message would not be
transmitted. The message “[999]Service Required” would flash the LED for up to 999
seconds.
Attempting to retransmit a message before pressing “cancel” within 30 seconds of the last
transmission will result in the red LED rapidly flashing for approximately 1 second.
Using this feature will decrease battery life only when actively flashing. A typical CR2032
coin cell will operate the 12-86-5000 for up to 200 hours of constant flashing (or
approximately 1000 transmissions).
