ThermoWorks Smoke X4 Four Channel Wireless Thermometer Instruction Manual

Getting Started:

Turn Smoke X4 and Smoke X4 Receiver on and within 30 seconds they will be connected (‘con’ will be displayed on Smoke X4 Receiver until it connects). Smoke X4 Receiver will update information every 30 seconds from the base unit while in range.

Wireless transmission can be turned on or off by pressing the wireless button on the rear of the base unit. Wireless signal can be received 6,562-feet (1.24-miles) line of-sight with no obstructions, less if transmitting between walls or obstacles (patent pending).

To set an alarm simply press “CH” to select the desired channel and then press “SET” to first turn the alarm function on or off. ALARM ON or OFF will begin to flash, use the arrows to change from on or off on the selected channel. Press “SET” again to accept the change and move to adjusting the HIGH ALARM. With the HIGH ALARM digits flashing use the up and down arrows to adjust the desired temperature. Press “SET” again to accept the HIGH ALARM changes and move on to LOW ALARM. With the LOW ALARM digits flashing use the up and down arrows to adjust the desired temperature. Press “SET” again to accept all changes and return to normal mode. Smoke X4 Receiver will show the updated alarm settings within 30 seconds of adjustment on the base unit. Alarms that are sounding can be muted with any button press either on the base or Smoke X4 Receiver.

You’re now ready to use Smoke X4 for the first time.

Smoke X4/Smoke X4 Receiver Sync Instructions

Smoke X4 and Smoke X4 Receiver come synced out of the box so you should only need to do this when replacing or adding additional Smoke X4 Receivers.

How to Sync Smoke X4 with Smoke X4 Receiver: 

  • With Smoke X4 powered on press and hold button for 5 seconds until “Sync” appears on the screen.
  • Now that Smoke X4 is in Sync mode, make sure Smoke X4 Receiver is powered on.
  • Press and hold the “VOL” button for 5 seconds on Smoke X4 Receiver. The display should read “Sync” for a short amount of time.
  • Both Smoke X4 and Smoke X4 Receiver will beep and return to normal functionality signaling a successful pairing.NOTE: To sync multiple Smoke X4 Receivers to one base, please follow the steps above on one Smoke X4 Receiver at a time. Putting Smoke X4 into Sync mode will not disable or interfere with previously synced Smoke X4 Receivers.

Tips for Use & Care Instructions

What’s Included: 

Smoke X4 (base), Smoke X4 Receiver (receiver), Batteries (Installed), (3x) Pro-Series® HighTemp Cooking Probe (TX-1001X-OP), Pro-Series® High Temp Air Probe & Grate Clip (TX1003X-AP), lanyard, 8 High Temp Silicone Color Probe Rings, and this instruction card.

Tips for Use: 

  • Your Smoke X4’s body should not be affixed directly to a smoker or grill’s lid or left in the smoker or oven. The high heat will melt the pastic housing.
  • Insert the cooking probe so that the tip rests at the thickest part of the meat or food. Avoid gristle or bone.
  • Pinch Grate Clip, insert probe, and attach clip to the grate. Place air probe 1 2 inches away from food, avoiding sides of the cooker.
  • Grate Clip can be adjusted for different-sized grates by gently bending. We recommend leaving the air probe in the clip while adjusting.
  • Set your desired alarm temperatures. Chef-recommended doneness temperatures are on the reverse of this card. If cooking meat, set the alarm somewhat lower to allow for carryover heat during resting.
  • The cables may be closed in an oven door or under a BBQ hood with the following precautions.

Cautions for Pro-Series Probes 

  • Use hot pads or gloves when removing the probe from meat. It will be hot!
  • Do not pull on the cable. Use the molded mini-handle.
  • The cables will withstand 700°F (370°C) and the transition/handle 644°F (340°C) for short periods.
  • Probe tip itself is rated to 572°F (300°C). Do NOT expose probe tip to flames or coals.
  • Construction is moisture-resistant but we do not recommend full immersion of the cable.
  • Clean probe by wiping with damp cloth and kitchen cleaner.
  • Keep the probe cable away from oven elements, flames, coals, grill or oven racks—all of which can reach temperatures far higher than 700°F (even if an oven is set lower). The probe cable can be damaged at higher temperatures. The inner insulation will melt and the probe will short (displaying “NO PROBE!” on the alarm display).
  • When using ovens or smokers, avoid pinching the cable between hot surfaces such as a cast metal grill hood without some insulating protection. Use an access hole if available.
  • Avoid repeated kinking or twisting of the probe cable which can break wires.
  • With care, the probe should last a long time. Eventually, you may need to replace it. If the probe becomes damaged, the base unit will flash “NO PROBE!”. Affordable replacements are available. See our website for full list of probe options.
