Instrument Security
Security options include two different electrical security options that alarms after a user 
designated number of temperatures is reached or when the unit is removed from the wall 
holder  (Model 692 only). A mechanical security option is also available to prevent removal of 
the unit from the wall mount or mobile stand without a special tool. The design of the 
SureTemp
®
 Plus Thermometers allows a facility to apply magnetic or RF security tags to the 
unit without adversely affecting the unit’s performance or functionality.
The SureTemp
®
 Plus Model 692 Thermometer has two distinct anti-theft systems available 
that are user selectable. Both systems require the use of a holder system with the 
thermometer. This setting will be retained in non-volatile memory when the batteries are 
replaced.
2.4.1 Temperature Count Security Feature
The Temperature Count security feature allows you to take a set number of temperature 
readings before the instrument goes into the security alarm state. The selectable counts are 
25, 50, 100, and 200. As the instrument nears the final reading, it will display SECURITY 
COUNT 
as a warning, along with a number representing the last 5 temperature counts (i.e., 
5,4,3,2,1) remaining on the security counter.
When the instrument enters the alarm state, it beeps for approximately 10 seconds. At this 
time, the instrument displays SEC on the LCD along with SECURITY COUNT in the ID field in 
the upper left-hand corner of the screen. The instrument is then disabled. Returning the 
instrument to the wall holder resets the security count. If the count is set to OFF, the 
temperature count function is disabled and no security alarm will occur.
This setting is programmable through the Biotech mode (page 11).
2.4.2 Instant-On Security Feature
When the Instant-On security feature is activated, the instrument goes into the security alarm 
state within five seconds after removal from the wall holder. When the instrument enters the 
alarm state, it beeps continuously and displays SEC on the LCD. Pressing the Mode 
Selection 
button while removing the probe from the probe well, within 30 seconds of the 
instruments removal from the wall holder, clears the alarm and allows the instrument to 
operate. Returning the instrument to the wall holder will reset the instant audio alarm.
The options for the Instant-On feature are ON and OFF. In the OFF setting, no security alarm 
will sound.
This setting is programmable through the Biotech mode (page 11).
