b) The actual BARBECUE temperature has exceeded your set maximum BARBECUE 
temperature. (Beep once in every second) 
 

 

c)

  The actual BARBECUE temperature has fallen below your set minimum BARBECUE temperature. 

(Beep once in every second)  

Note: The minimum BARBECUE temperature alarm will not be activated until the actual 
BARBECUE temperature goes above the set minimum temperature. 

 

 

For example: You set the minimum BARBECUE temperature as 220 ºF and press the ALERT, ºC /

 

ºF, STOP/START to activate the alarm. The unit will NOT beep or flash even if the actual BARBECUE 
temperature is below 220 ºF. It assumes that your BARBECUE is not up to temperature. Only when the 
actual BARBECUE temperature goes over 220 ºF, then falls below 220 ºF, can the alarm be activated, 
the unit will beep and flash.

 

 

Note: The unit will retain your Barbecue & Food alert temperature settings even 
after the unit is turned off.

Temperature display formats

 

Press and hold the ALERT, ºC /ºF, START/STOP button for 2 seconds to switch between ºC and ºF.

 

 

Using TIMER MODE & TEMPERATURE MODE simultaneously

 

The TIMER MODE and TEMPERATURE MODE can be used simultaneously. This allows you to monitor 

the temperature for both FOOD and BABECUE in the TEMPERATURE MODE when using the TIMER 

MODE to keep track of another cooking task. You can tell different task by the alarm sound as well as the 

icons.

 

 

1.

  In the THERMOMETER MODE, when the temperature is reached, the receiver will alarm you by 

beeping once in every second for the BARBECUE temperature and beeping twice in every second for 

the FOOD temperature. The alarm icons and probe temperature will blink along with the alarm sound.  

 

2.

  In the TIMER MODE, when the timer is reached, the receiver will alarm you by beeping 3 times in 

every second. Either the upward arrow (for count-up) or downward arrow (for countdown) will blink.  

 

Procedure for typical use in an outdoor BARBECUE

 

 

The following typical examples will go through the steps to have the ET-732 REDI CHEK BARBECUE 
alarm you if a piece of meat (Boston Butt) is cooked to 160 ºF if your barbecue temperature falls below 
225 ºF or goes above 250 ºF, and remind you to check the smoker in 2 hours.

 

 

Set up BARBECUE

 

Follow the registration procedure.

 

Place meat on the BARBECUE grill rack.

 

Insert FOOD probe sensor into the center of thickest portion of the meat. Avoid touching bone or heavy 

fat areas.

 

Clip the special BARBECUE probe to grill rack of barbecue chamber.

 

 

Position the probe sensor wires so they will not come into contact with flames and exit the 

barbecue without being pinched/ crushed by the cover.

 

 

Stand/ hang the transmitter away from heat source of barbecue. DO NOT put transmitter on closed 
cover or under the cover. The transmitter is water proof for use in rain.

 

 

In THERMOMETER MODE

 

Press HI/CLEAR to display the maximum FOOD temperature.

 

Press and hold HI/CLEAR until the maximum FOOD temperature flashes.

 

Press HI/CLEAR repeatedly until 160 ºF appears (press and hold HI/CLEAR button will increase the 

temperature 10 degrees per second)

 

 

Quickly press LIGHT/MODE to confirm the 160 ºF setting.

 

 

Press HI/HR to display the maximum BARBECUE temperature.

 

Press and hold HI/HR until the maximum BARBECUE temperature flashes.

 

 

Press HI/HR repeatedly until 250ºF appears (press and hold HI/HR button will increase the 

temperature 10 degrees per second)

 

 

Quickly press LIGHT/MODE to confirm the 250ºF setting.

 

 

Press LO/MIN to display the minimum BARBECUE temperature.

 

Press and hold LO/MIN until the minimum BARBECUE temperature flashes.

 

 

Press LO/MIN repeatedly until 225 ºF appears (press and hold LO/MIN button will increase the 

temperature 10 degrees per second)

 

Quickly press LIGHT/MODE to confirm the 225 ºF setting.

 

 

Press ALERT, ºC /ºF, START/STOP to activate the temperature alarm for the BARBECUE and FOOD.

 

 

In TIMER MODE

 

 

Press HI/HR twice to set for 2 hours so that 2:00 will be displayed. 

Press ALARM/START/STOP to start the countdown.

 

Press and hold LIGHT/MODE to go back to THERMOMETER MODE.

 

 

Clip the receiver to your belt or pocket and move up to 300 ft away from the barbecue. Go indoors if 
desired. You are now remotely monitoring your food and barbecue. The receiver will beep and flash if 
your meat temperature goes above 160 ºF or the barbecue temperature falls below 225 ºF or exceeds 
250 ºF.

 

Helpful Hints

 

If the receiver and / or the transmitter display LLL or HHH instead of the probe temperature, wait for 

probe to reach room temperature. If LLL or HHH is still displayed or you get a false temperature, 

squeeze the probe jacks harder into the transmitter and twist them back and forth so they make good 

contact. If the problem still persists it is likely the internal probe wire has shorted out either through 

moisture or heat damage.

 

 

Do not immerse the probe in water while cleaning.

 

 

Do not allow the probe or probe wire to come into contact with flames.

 

 

Within the warranty period, return defective probe to address below along with return address and we 
will send you a replacement probe at no charge.

 

 

If the temperature displayed seems to read too high or the temperature seems to increase too quickly, check to 
make sure the probe tip is not poking through the food to outside. Reposition the probe tip in the center of the 
thickest part of food. Avoid touching bone or heavy fat areas.

 

 

Cautions:

 

1)

  Always wear a heat resistant glove to touch the stainless steel probe sensors or wires during or just 

after cooking. Do not touch with bare hands.  

 

2)

  Keep the stainless steel probe sensors and wires away from children.  

3)

  Clean the stainless steel probes and dry thoroughly after each and every use.  

4)

  Do not use the receiver in the rain. It is NOT rain proof. The transmitter is rain proof but not water 

tight. Do not immerse in water.  

 

5)

  Do not expose the plugs of the stainless steel probes or the plug in holes of the transmitter to water 

or any liquid. This will result in a bad connecting and faulty readings.  

 

6)

  Do not expose the receiver or transmitter to direct heat or surface.  

7)

  Do not use stainless steel probes in microwave oven.  

8)

  The Barbecue Thermometer registers temperatures as low as 32 ºF (0 ºC) and as high as 572 ºF (300 

ºC). LLL will be displayed below 32 ºF and HHH will be displayed above 572 ºF. Do not use the 

stainless probe sensor above 572 ºF. Doing so will deteriorate the wire.  

 

9)

  Not Intended for Use by Persons ages 12 and Under.  

 

Cleaning

 

1)

  Always wear a heat resistant glove to touch the stainless steel probe sensors or wires during or just 

after cooking. Do not touch with bare hands.  

 

2)

  Keep the stainless steel probe sensors and wires away from children.  

3)

  Wash the metal probe tips with hot soapy water and dry thoroughly. Do not immerse the probe in 

water while cleaning.  

 

4)

  Wipe the transmitter and receiver with damp cloth. Do not immerse either in water.
