Description

The Rossmax Digital Medical Thermometer TG380 is built with durability and ease of use in mind. Its compact size and lightweight design make it easy to carry around, while its large LCD display ensures clear visibility of temperature readings. The device comes with a set of disposable probe covers, which enhance hygiene and reduce the risk of cross-infection.

The thermometer also includes a mute function, allowing for silent operation when needed, and an auto-shutoff feature to conserve battery life. These features combine to make the Rossmax TG380 an indispensable tool for healthcare professionals and home users alike.

How to Use

Push the On/Off button by the display window. The display will read for 2 seconds, and a beep sound will be heard.
Release the On/Off button, and the last measured temperature will be shown for about 2 seconds. Then, the self-test temperature of 37.0°C (98.6°F) will display, followed by "Lo°C" (or "Lo°F").
Wipe or dip the probe with alcohol for disinfection. Position the probe in the oral, rectal, or axillary site.
Once the degree sign °C (°F) on the display has stopped flashing (usually within 10 to 40 seconds), a beep signal will sound approximately 10 times. The measured temperature will then be shown on the LCD window. The temperature reading will not change after the unit is removed from the testing position.
- If the temperature is less than 37.8°C (100.0°F), the buzzer will sound:
  "Bi---Bi---Bi---Bi---"
- If the temperature is greater than or equal to 37.8°C (100.0°F), the buzzer will sound a higher frequency:
  "Bi-Bi-Bi----Bi-Bi-Bi--" (approximately 10 times).
The unit will automatically turn off in 10 minutes for energy-saving purposes. However, to prolong battery life, it is recommended to press the On/Off button to turn off the unit once the measurement is done.
Dispose of any used batteries and the thermometer according to local regulations.

Note: After step 2, if the room temperature is greater than 32.0°C (89.6°F), the room temperature will be displayed.
Note: Using the probe cover may result in a 0.1°C (0.2°F) difference from the actual temperature.
Note: Clean the probe before and after using the thermometer to ensure accurate readings and to avoid cross-contamination.

Oral Use

Place the probe well under the patient’s tongue.
Ensure the patient keeps their mouth closed for about 20 seconds.
Do not drink hot or cold fluids, exercise, smoke, or engage in other activities prior to the reading. These activities may raise or lower temperature readings compared to the patient’s normal, average temperature.

Axillary Use

Tightly place the probe in the patient’s armpit for about 30 seconds.

Please ensure close contact between the probe and the armpit, especially for babies or children.

Rectal Use

Always use a probe cover when taking rectal measurements.

Commonly used for young children when it is difficult to take an oral or axillary temperature.
Lubricate with a water-soluble gel. Do not use petroleum jelly.
Gently insert the probe tip no more than 1.5-2 cm into the rectum for about 10 seconds. Do not force the tip into the rectum if resistance is encountered.
Disinfect the thermometer after use. Refer to the “Cleaning and Disinfection” section.

°C / °F Switchable

Temperature readings are available in either the Fahrenheit or Celsius scale (°C / °F; located to the right of the LCD). With the unit off, press and hold the On/Off button for approximately 4 seconds to change the current setting.

Battery Replacement

When the battery icon appears on the upper right corner of the LCD, the battery is exhausted and needs replacement.
Pull the battery cover off in the direction shown.
Pull out the battery with a sharp object such as a pen. Keep exhausted batteries out of reach of children.
Place a new 1.5V D.C. button-size battery (type SR41 or LR41 or equivalent) in the chamber with the positive side facing up and the negative side facing down.
Install the battery cover back.

Setup Guide

Setting up and operating the Rossmax Digital Medical Thermometer TG380 is straightforward:

Insert the batteries into the battery compartment according to the polarity markings.
Attach a disposable probe cover to the thermistor tip if using orally or rectally.
Select your preferred measurement mode using the mode button.
Place the thermistor tip under your tongue (orally), in the rectum (rectally), or in your armpit (underarm) and hold until you hear a beep indicating that measurement is complete.
Read your temperature on the LCD display.

Cleaning and Disinfection

Clean the unit by wiping it with a dry cloth and sterilize the probe with ethyl alcohol.
Do not let the unit come into contact with any chemical thinner.
Do not soak the display in water.

Caution

Do not bend, drop, or twist the thermometer. It is not shockproof.
Do not boil the probe for disinfection.
Do not store the unit under direct sunlight, at high temperatures, in high humidity, or in dusty environments. Avoid sunlight and extreme temperatures or humidity.
Do not disassemble the unit. See the Battery Replacement section to replace the battery.
Avoid strong electromagnetic interference from devices like microwave ovens and cell phones.
Ensure the probe is dry before placing the thermometer into the carry case.
The thermometer contains small parts (battery, etc.) that can be swallowed by children. Never leave the thermometer unattended with children.
Clean the thermometer after every measurement, whether or not the probe cover was used.
Keep the battery away from children. It can be harmful if swallowed.
Do not charge or expose the battery to extreme heat, as it may explode.
This thermometer is intended for oral, axillary, and rectal use only; do not use it in the ear.
Using the probe cover may result in a 0.1ºC (0.2ºF) discrepancy from the actual temperature.
Remove the battery from the thermometer when not in use for a prolonged period.
If the unit was stored in an extreme environment before use, ensure it has acclimatized to room temperature before taking measurements.
This is a home healthcare product only and is not intended to substitute the advice of a physician or medical professional.
Do not use this device for diagnosis or treatment of any health problem or disease. Measurement results are for reference only. Consult your physician if you suspect any medical problems. Do not change your medications without your physician's advice.
This device may not meet its performance specifications if stored or used outside the specified temperature and humidity ranges.
If this device is used according to the operating instructions, periodic re-calibration is not required. If you have further questions, please send the device to the dealer.
Do not dispose of the product in household waste at the end of its useful life. Disposal can take place at your local retailer or appropriate collection points.
This device is for oral, axillary, and rectal use only.
High, prolonged fever requires medical attention, especially for young children. Please contact your physician.
For safety reasons, during children’s temperature measurement, keep them from crying, walking, talking, or engaging in any related dangerous activities.

NOTE UT is the a.c. mainsvoltage prior to application of the test level.

At 80 MHz and 800 MHz, the higher frequency range applies. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the TG250/TG380 is used exceeds the applicable RF compliance level above, the TG250/TG380 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the TG250/TG380.
Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.

Recommended separation distance between portable and mobile RF communications equipment and the TG250/TG380
The TG250/TG380 is intended for use in an electromagnetic environment in which radiated RF distur- bances arecontrolled. The customer or the userof the TG250/TG380 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the TG250/TG380 as recommended below, according to the maximum output power of the communications equipment.
