The Model 386 Count Down Timer is a timer with an audible alarm output. It is housed in a standard wall switch enclosure for easy, permanent installation. The Model 386 timer was designed as a “treatment timer” and is useful in areas requiring an audible alarm at the end of a treatment, such as a tanning bed.The Model 386 is knob-adjustable from 1 to 60 minutes. There is a user replaceable 9V battery inside and should provide one to six months of operation. The previous set time is remembered each time the battery is changed as well as when the timer wakes up; this allows for easy repeatable timing without the need to adjust the knob. There are two LEDs; the upper one is the timing/timed out, and the lower one symbolizes “set mode” and low battery information. Note: To change the time, press and hold the button until the lower LED begins flashing green, when finished, press the button again to “lock-in” and store the value.
